This apparatus and the method of use relates to water supply systems. More particularly, the invention relates to a water meter and leak detection system for private and/or public property(ies) to monitor and provide water use and water leak information and to minimize water loss and related damage.
Water is increasingly becoming a precious resource. While fresh water supplies have been challenged due to climate (short rainy seasons and long droughts) and increased pollution, water demand has been rising due to the growing population along with increased development. The increasingly limited supply of fresh water is a humanitarian concern and water conservation is becoming a major issue for many communities. An apparatus for real-time monitoring of water use and real-time detection of leak conditions at private and/or public property(ies) (e.g., residential structures and yards, business/industrial/commercial facilities, and governmental/institutional sites) can be useful in assessing and controlling water resources and supporting water conservation.
Water losses to private and/or public properties caused by broken or compromised water pipes and by unobserved leaks are enormous. Broken or compromised water pipes are often underground and are undetected, or, for example, when the property owner is absent or sleeping, and the resulting water loss and property damage can be catastrophic. Property insurance agencies report that a significant portion of total insurance losses are water related. It has been found that losses due to water leaks in residential homes amount to a significant percentage of the total water use.
The water meter and leak detection System monitors real-time water use and provides real-time leak detection with notification for private and/or public property(ies) (e.g., residential structures and yards, business/industrial/commercial facilities, and/or governmental/institutional sites). The water meter and leak detection system connects in series to the water supply for one or more private and/or public properties. This invention comprises a water meter collection node and an optional communication hub or receiving station. The collection node is essentially a water meter which can include: one or more water flow rate sensors, one or more optional control valves, one or more optional temperature sensors, one or more optional pressures sensors, one or more optional acoustic sensors, and wireless radio technology. Use of the optional communication hub or receiving station provides longer wireless range capability. The water meter collection node with or without the optional communication hub or receiving station can utilize long range wireless technology [LoRa, Sigfox, WiMAX, Ultra Narrow Band (UNB), 6LoWPAN, standard WiFi and WiFi3 (with Wi-Fi extenders)], limited range technology [Bluetooth, Bluetooth low energy (BLE), Zigbee and Z-wave], other wireless technology, wired and wired technology [X10, universal powerline bus (UPB), HART Communications Protocol], established cellular technology [3GPP, LTE-M, NB-IoT, and 5G], and any combinations thereof.
In one embodiment, the water meter collection node utilizes a LoRa, WIMAX, 6LoWPAN, ultra narrow band (UNB), or NB-IoT radio that communications with the optional communication hub or receiving station that has a corresponding LoRa, WiMAX, 6LoWPAN, ultra narrow band (UNB), or NB-IoT radio that communications with the collection node, and the optional communication hub has a second radio with a Wi-Fi or Wi-Fi3 technology that communicates with a wireless router. In addition, the communication hub can be hard-wired to a wireless router using the ethernet ports. Bluetooth, Bluetooth low energy {BLE), Zigbee or Z-Wave can also be used for shorter range communications. The wireless communication technology can utilize and communicate with an application programming interface (API) protocol, a simple object access protocol (SOAP), a representational state transfer (REST} protocol, or another API technology. The API interface is software code that allows two programs to efficiently communicate with each other for website presentation. The wireless technology is in duplex format as water use monitoring transmits water use data to a remote server while the leak detection capability needs to send a signal to control the water control valve. The long range wireless technology (LoRa, Sigfox, WiMAX, UNB, 6LoWPAN, NB-IoT, standard Wi-Fi and Wi-Fi3 (with Wi-Fi extenders), limited range technology (Bluetooth, BLE, Zigbee and Z-wave), wired technology (X10, UPS, HART Communications Protocol), established cellular technology (3GPP, NB-IoT, LTE-M), and any combinations thereof transfers data through a private or corporate network system or through a router connected to the internet. These methods of transfer communicate water use, water leaks, and/or water quality data to remote server(s) with database(es) The water meter and leak detection system is connected to the water supply piping using a continuous, water flow event use (basis), or on a demand basis for monitoring water use from the main water supply line used within a private and/or public property{ies}. The present invention can be used with private and/or public water sources such as public municipalities and/or private wells and other non-municipal related water sources. The remote server and database can be used to support a computer portal that designated or registered users or owners can access water use data and/or leak detection information on a cell or smart phones, computers, or similar apparatuses can use to access and observe water use, leak conditions, and/or water quality parameters for relevant private and/or public property(ies).
The housing of the water meter and leak detection system collection node and optional communication hub or receiving station can be fabricated from materials and can use technologies that provide protection for moist and wet conditions, hot environments and cold/freezing situations. The water meter and leak detection system includes a central processing unit (CPU), microprocessor and/or microcontroller, data storage, timing and wireless circuitry, water flow rate sensors, optional water quality sensors, optional pressure sensors, optional acoustic sensors, and a power generation means. The types of water flow rate sensor(s) can be invasive (i.e. within water pipe; e.g. turbine sensor), non-invasive (i.e. outside water pipe; e.g. ultrasonic sensor), and/or sensitive water flow sensors (e.g. pressure sensor). The water meter and leak detection system has the capability to utilize several different sensors to accomplish the goals of real-time monitoring water use and detecting leaks. Furthermore, the water meter and leak detection system can monitor separately indoor and outdoor water use or can monitor one or more designated areas of one or more sites. Optionally, a temperature sensor can be incorporated into the water meter collection node to determine, communicate, and address temperature conditions, e.g. assess freezing conditions (water temperature is approaching 32 degrees Fahrenheit or 0 degrees Celsius) and communicate with the property structure's thermostat or heating system to maintain a specified temperature within the structure, drain water from pipes, and/or perform other damage protection techniques. The optional pressure sensor, with associated use of the control valve, can be used for detecting [very] extremely small leaks. This is accomplished by shutting off the water supply with the control valve and monitor pressure over time. The resulting loss of pressure can generate graphical curves or charts that demonstrate that type of small leak, e.g. leaking faucet, leaking toilet flapper valve. The pressure sensor can also be used to detect pressure fluctuations during standard flow conditions.
The water meter and leak detection system with control valve(s) can be shut-off/on manually or be programmed to automatically turn off the water control mechanism. when a leak is detected, or program for a schedule using a cell or smart phone, computer, or other electronic apparatus. The water meter and leak detection system can be programmed to follow a work, vacation, leak monitoring or other schedule. The water meter and leak detection system can be set to automatically shut-off when the private and/or public property{ies) is unoccupied or vacant. The occupancy of the private and/or public property(ies) can be determined by feedback from electronic lock{s), passive infrared sensor(s) (PIRs), alarm(s), security system(s), or other security devices. Furthermore, the water meter and leak detection system is designed with electrical and communication circuitry to send a signal to the cell or smart phone, computer, or other electronic apparatus that the water supply line is on or off.
The water meter and leak detection system provides wireless remote leak detection notification using water event or water event basis monitoring and software analysis. Alternately, continuous data monitoring can be stored in a data module in the water meter collection node and periodically transferred wirelessly to a remote computer or server as described herein. The water meter and leak detection system monitors water use and detects non-typical, abnormal, or continuous water use and alerts, signals, or messages via a cell or smart phone, computer, or other electronic apparatus to one or more property owners, users, or responsible individuals of any water leak condition(s). Thus, leak notification can be provided when the property(ies) is vacated or unsupervised.
The water meter and leak detection system's collection node communicates through a private or commercial network system or communicates with the optional communication hub or receiving station and through a router to the internet.
The water meter and leak detection system's collection node with water shut-off/on mechanism can be battery operated and can utilize re-chargeable batteries or super capacitators. The re-chargeable components can be connected to electricity generation means such as a water turbine generator(s), solar cell(s), or wind generation means to supplement electrical energy. The Water Meter and Leak Detection System with shut-off/on mechanism can also be AC or DC powered.

Water Use refers to the total volume or volume of water used over a period of time.
Water flow event or water flow event basis is defined as monitoring and sensing the initiation of water flow until the water flow is stopped, whereby the water flow rate, the duration of water flow, and the total water volume can be calculated and recorded. The water flow event will inherently save CPU and wireless transmission energy by not recording or transmitting no water use data and allowing the CPU or microprocessor to go into a sleep mode between each water event use thereby providing a superior method for analyzing water signatures and patterns for reliable discernment of leak and leak locations.
Private and/or public property(ies) refers to the structure(s), site(s), area(s), land(s), and/or location(s) whether indoor, outdoor, or a combination thereof that is/are owned, controlled, used by or designated for use by any type of entity(ies) (i.e. personal, residential, commercial, corporate, business, industrial, establishment, government, administrative, institutional, organizational, etc.). Examples include but are not limited to homes and yards, office buildings, commercial structures and grounds, farming lands, government or institutional facilities, multi-unit apartments, condominiums or townhomes, hospitals, dormitories, university or corporate campuses, water or irrigation system defined areas, water wells, sports fields, exercise facilities, parks, golf courses, home owner association (HOA) areas, and military bases.
Authentication refers to the technology that confirms or ensures that a message(s), control/command signal(s), data, and/or information that is downloaded and/or transferred from one person or device to another that is received only by the intended person or device. One example of an authentication method is the Challenge Handshake Authentication Protocol (CHAP) which provided authentication technology to a user communication with a network entity, which may be any remote private or corporate server and/or the Internet using a service provider (e.g. ATT U-verse, Xfinity/Comcast) CHAP provides users authenticated passwords when accessing remote servers, which also are authenticated prior to allowing the user access. For example, short distance wireless technology Bluetooth, Bluetooth low energy, Zigbee, Z-wave and Wi-Fi short range wireless technologies can be used for an authentication pairing procedure to initially establish remote wireless communications. Such authentication pairing procedure can be inputting a Service Set Identifier (SSID) and password which can include two factor authentication.
In the water meter environment, encryption refers to a privacy technology that uses a process of encoding which prevents any individual mobile communication device or water meter but the intended recipient mobile communication device or water meter to access, download, read, or review a message(s), control/command signal(s), data, and/or information by providing a confidential transfer between the individual, mobile communication device or water meter one or more sensors transferring data or information to a remote computer or server.
In the water meter context, integrity refers to technology that ensures that a message(s), control/command signal(s), data, and/or information transferred from a water meter to another meshing water meter, or to a remote computer or mobile communication device (cell phone), is not altered, compromised, or corrupted, completely lost or having partially lost segments, during transmission or when accessed or downloaded.
In the water meter environment, non-repudiation refers to the technology that confirms or ensure and prevents a sender or receiver from denying that a message(s), control/command signal(s), data, and/or information was sent or received. Block chain technology is an upcoming technology that will ensure non-repudiation compliance.
Cellular format technology refers to all current and future variants, revisions and generations [e.g. third generation (3G), fourth generation (4G) and 3GPP (and enhancement revisions), fifth generation (5G), 3GPP cellular technology, all future generations of Global System for Mobile Communication (GSM), General Packet Radio Service (GPSR), Code Division Multiple Access (CDMA), Evolution-Data Optimized (EV-DO), Enhanced Data Rates for GSM Evolution (EDGE), 3GSM, Digital Enhanced Cordless Telecommunications (DECT), Digital AMPS (IS-136/TDMA, Integrated Digital Enhance Network (iDEN), HSPA+, WiNAX, LTE, Flash-OFDM, HIPERMAN, WiFi, IBurst, UMTS, W-CDMA, BSPDA+HSUPA, UNTS-TDD, other formats for utilizing cell or smart phone technology, telephony antenna distributions, and/or any combinations thereof] and includes the use of satellite, microwave technology, the internet, cell tower, telephony, and/or public switched telephone network lines.

LoRa, also known as LoRaWan (and referred to as “LoRa” herein) comprises a low-power wide area and long-range network protocol based on Semtech or HopeRF LoRa technology for IoT devices, and LoRa networks and machine-to-machine (M2M) applications. LoRa uses chirp spread spectrum (CSS) technology developed by the company Semtech. Chirp spread spectrum modulation, which is like Frequency Shifting Keying (FSK) modulation, but it increases the communication range significantly. Chirp spectrum uses its entire allocated bandwidth to broadcast a signal. Because the chirp spectrum utilize a broad band of the spectrum, chirp spread spectrum is also resistant to multi-path fading even when operating at very low power. Also, chirp spread spectrum is resistance to Doppler effect, which is typical in radio applications. LoRa focuses on secure bi-directional communications in an asynchronous protocol that is designed for long wireless range with extended battery life. LoRa manufacturers use the entire allocated bandwidth to broadcast a communication or signal, making the LoRa protocol robust to minimize channel noise and excellent at handling interference and overlapping networks. The LoRa protocol provides interoperability among smart devices without the need of complex local installations. LoRa network architecture is based on a star-of-stars topology with gateways as a transparent bridge relaying messages between end-devices and a central network server in the backend. Existing gateways are connected to the network server via standard internet protocol connections while end-devices use single-hop wireless communication to one or many gateways. All communication is generally bi-directional or duplex format, but also supports multicast operations for enabling software upgrades or mass distribution messages to reduce the on-air communication time. Communication between end-devices and gateways is spread out on different frequency channels and data rates. The selection of the data rate is a trade-off between communication range and message duration. Due to the spread spectrum technology, communications with different data rates do not interfere with each other and create a set of “virtual” channels increasing the capacity of the gateway. LoRa data rates range from 0.3 kbps to 50 kbps. To maximize both battery life of the end-devices and overall network capacity, the LoRa network server can manage the data rate and radio frequency output for each end-device individually by means of an adaptive data rate (ADR) scheme. The LoRa technology offers high penetration, low bandwidth, low energy, long range wide area, and secure data that is gaining significant traction penetration into the IoT networks.
The LoRa wireless system makes use of the unlicensed frequencies below 1 GHz that are available worldwide:
Using lower frequencies than those of the 2.4 or 5.8 GHz ISM bands enables much better coverage to be achieved especially when the nodes are within buildings enabling superior penetration of large buildings and penetrate solid walls.
Lora's main and upcoming competitor is Sigfox which employs the differential binary phase-shift keying (DBPSK) and the Gaussian frequency shift keying (GFSK) that enables communication using ISM radio bands 868 MHz in Europe and 902 MHz in the United States. Sigfox utilizes a wide-reaching signal that passes freely through solid objects and is considered to be a “Low-power Wide-area network” or LPWAN. The Sigfox signal can also be used to easily cover large areas and to reach underground objects. Presently Sigfox technology is being installed and utilized throughout the world as a wireless platform for IoT communications.
With traditional Wi-Fi, most networks were designed on the ranges delivered by 802.11 standard operating frequencies 2.4 and 5.8 GHz and protocol for distance and performance. Newer Wi-Fi technology being developed is known as WiFi3. In the foreseen near future, companies like Edgewater Wireless will develop and market Wi-Fi3 powered technology that will deliver reliable, high-capacity indoor and outdoor Wi-Fi wireless communication and protocols for high-density environments. The high channel density will enable multiple channels of a single chip meaning aggregate output on a single Wi-Fi3 enabled device will outperform traditional, single channel Wi-Fi technology. Thus, the fewer access points will deliver higher quality of service that can considerably lower the cost of deployment of IoT devices. Remote and rural infrastructure installations are easily achievable due to the extended network coverage and performance capabilities of Wi-Fi3.
WiMAX refers to interoperable implementations of the IEEE 802.16 family of wireless-networks standards ratified by the WiMAX Forum. Wireless WiMAX suffers like most other wireless technology that the further away from the source the slower their connection becomes. The WiMAX Forum has proposed an architecture that defines how a WiMAX network can be connected with an IP based network. WiMAX Forum published three licensed spectrum profiles: 2.3 GHz, 2.5 GHz and 3.5 GHz, to establish standardization.
Ultra Narrow Band (UNB) refers to technology that transmits over a very narrow spectrum (for example less less than 1 KHz) to achieve ultra-long range for data communication between a sensor collection node transmitter or a communication between a sensor collection node transmitter and a communication receiving hub. By transmitting in a UNB channel, little power is required to transmit data over a considerable distance. UNB systems are frequently used in one-way, half duplex e.g. from collection node sensor(s) to an optional communication hub but can mimic two-way full duplex communication when the receiver/sensor is sleeping most of the time and must open once a few times each hour to listen for signal commands or messages.
The goal of the NB-IoT is another wireless technology designed to address the needs for very low data rate devices that need to connect to mobile networks, and often powered by battery power. Because NB-IoT is a cellular-based wireless technology that uses orthogonal frequency division multiplexing (OFDM) modulation, the chips are more complex to manufacture. Using typical cellular technology to obtain a high level of performance is penalized with an increase cost associated with involved tower installations and greater power consumption. NB-IoT is similar to Sigfox and LoRa but has a much faster modulation rate that can handle a lot more data than those Sigfox and LoRa technologies. However, NB-IoT is not an IP-based communication protocol A user can usually not communicate or access an IP network with NB-IoT or expect to use it with an APP running on a cell phone or smartphone. It was made for simple IoT applications and is more power efficiency.
6LoWPAN is an acronym that combines the new Internet Protocol (IPv6) with a sub 1 GHz frequency and low power wireless personal area networks. The 6LoWPAN supports hundreds of hops for developing wireless mesh networks with high self-healing (node failure) and self-maintenance of mesh routes. The 6LoWPAN architecture consists of a local network with routers/servers which utilizes a one or more edge router(s) to connect to the access network. The one or more edge router(s), communicating with the internal servers, then provides the IoT sensor and applications to access to the internet. IPv6 is also in use on the smart grid network enabling smart meters (water meter and leak detection systems) and other devices to build a micro mesh network before sending the data back to the main remote servers with database for monitoring and billing operations.
Bluetooth Low Energy (BLE) refers to a newer version of standard Bluetooth. Standard Bluetooth was originally designed for continuous streaming of data applications. Both standard Bluetooth and BLE low energy operate in the 2.4 GHz ISM band. However, the BLE remains in a sleep mode constantly except for when a connection is initiated. The actual connection times are on a few milliseconds, unlike standard Bluetooth's continuous streaming. BLE short time connection allows for higher data transfer rates of approximately 1 Mb/s.
Cellular (3GPP) refers to refers to a 3rd Generation. Partnership that formulated the original release 8 and the associated enhancements (9-14). The original LTE 4G release 8 included high peak data rates, up to 300 Mbps in downlink and 75 Mbps in uplink when using a 20 MHz bandwidth that includes high spectral efficiency and flexible bandwidths (1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz and 20 MHz), 5 millisecond latency for IP packets in ideal radio conditions, simplified Architecture, orthogonal frequency-division multiple access (OFDMA) in downlink and Single-carrier frequency-division multiple access scheme (SCFDMA) in uplink, all IP network, and using the multiple in and multiple out (MIMO) multiple antenna pattern.
The LTE Cat-MI (also known as LTE-M} technology is designed for Internet of Things (IoT) devices. The LTE-M has different data speeds, frequency spectrum, power usage and signal range. LTE-M trades in data rate for better power efficiency and longer signal range and is therefore considered an “Internet of Things” (IoT) cellular technology. The 5G connects directly to a network, without the typical node/computer network that passes traffic from a local network to other networks or the Internet router (a gateway). Devices can connect to 5G networks with microchips that are less expensive to fabricate because these microchips are half-duplex and have a narrower bandwidth. Such designed devices can enter a “deep sleep” mode called Power Savings Mode (PSM) and only wake up periodically while connected. Because the maximum data rate of LTE-Cat-Ml (LTE-M) and 5G devices is only about 100 kbits/s, these cellular protocols do not burden the typical cellular network. Cellular 5G version uses a system of cell sites that divide their territory into various sectors and send encoded data through radio waves. Each cell site must be connected to a network backbone, whether through a wired or wireless connection. 5G networks will use a type of encoding called orthogonal frequency-division multiplexing (OFDM), which includes an interface that will be designed for much lower latency and greater flexibility than LTE-M. The 5G networks differ from 4G networks by managing significantly more, smaller cells that can dynamically change their size and shape so 5G networks need to be more intelligent than previous systems like 4G. But with existing macro cells, 5G is expected to boost capacity by over current 4G systems by utilizing wider bandwidths and advanced antenna technologies.
Wired communication can be standard wired technology, such as X10, UPB and the HART Communication Protocol (Highway Addressable Remote Transducer). X10 is a protocol for communication among electronic devices primarily used in the home automation industry. It primarily uses the power line wiring for signaling and control, where the signals involve brief radio frequency bursts representing digital information that transmits along the previously installed home electrical wiring. Universal Powerline Bus is a proprietary software protocol for power line communications between devices and again used for primarily in the home automation industry. Household electrical wiring is used to send digital data between UPB devices using pulse position modulation. The newer UPB protocol is more reliable that the older X10 technology, which allowed the UPB protocol to significantly penetrate the wired market. Communication can be peer to peer with no central controller necessary. The HART Communication Protocol (Highway Addressable Remote Transducer) is a hybrid analog+digital industrial automation open protocol. Its most notable advantage is that it can communicate over legacy 4-20 mA analog instrumentation current loops, sharing the pair of wires used by the analog only systems. HART is widely used in process and instrumentation systems ranging from small automation applications through highly sophisticated industrial applications. Due to the huge installed base of 4-20 mA systems throughout the world, the HART Protocol is very popular for industrial protocols.
The terms wired (e.g. X10, UPB, HART Communication Protocol) and wireless electronic communication (e.g. Wi-Fi, Wi-Fi version 3 or WiFi3, 6LoWPAN, ZigBee, Z-wave, Bluetooth, Bluetooth low energy (BLE), WiMAX, long range low power technology such as LoRa, Ultra Narrow Band (UNB), and cellular technology 3GPP and LTE-M and 5G) correspond to the concept of “internet of things” or “IoT”. The internet of things is defined herein as a network of physical objects or things that is comprised of electronic apparatuses (collect node and communication hub), programmable software, various sensor technology (flow, temperature and water quality and leak detectors), and local routers/servers and/or remote network and internet connectivity, which enable apparatuses to collect and exchange data. The internet of things allows devices to be sensed and controlled remotely across existing network infrastructure, creating opportunities for more direct integration between the physical world and computer-based systems and resulting in improved efficiency, monitoring accuracy and economic benefit. The internet of things encompasses technologies such as smart grids, smart homes, and intelligent wire and wireless electronic communications.

The electronic communication(s) comprises, in part, a segment of the internet of things (IoT) concept. The wireless communication 54 or wireless communication 46 can also electronically communicate with a local router/server which uses the internet to communicate with remote computers (cloud) to allow remote access of the water use data. Such remote cloud-based computers can be provided by a large commercial cloud computer company.

TCP/IP technology has become a common communication and management platform for sensor to device applications, so software developers can utilize multiple communication systems while using TCP/IP technology. TCP/IP is a combination of two technologies where TCP comprise the fourth layer, and IP comprises the third layer, of the network and transport sections of the Open Systems Interconnect model (OSI model). Wireless technology such as LoRa, WIMAX, 6LoWPAN, UNB, Wi-Fi/Wi-Fi3 (with WiFi extenders), Cellular 3GPP, and/or LTE-M, NB-IoT and 5G, Bluetooth and BLE, ZigBee, Z-wave or similar wireless protocols or other communication technologies using the TCP/IP technology to transfer or download water data from a private or public property(ies) or used to upload data, information or software updates to the water mater and leak detection system 10 (126 shown in
Calibration of the sensors with the water meter and leak detection system 10 (126 shown in
In another embodiment, the multiple independent flow sensors 105 can be engaged to the main water supply, irrigation system, or water use devices such as washing machine, water heater, dishwasher, kitchen faucets, bathroom faucets, shower, and/or toilets, and any combinations thereof. Each independent flow sensor 105 sends a unique code to the CPU, microprocessor or microcontroller 84 for identification associated with the water use device. Each independent flow sensor 105 can communicate the water usage by wired or wireless communicating with a unique code to the water meter and leak detection system 10 (126 shown in
In another embodiment, which does not utilize an independent flow sensor at each water use device but rather a single flow sensor, can allow an owner/user to enter into a programmed “Device Calibration Mode” by pressing a specific hard or soft button (126 shown in
It is anticipated by the Applicant that an “Automatic Sensor Learning Mode”, where the software learns about the users water use at a private or public property (ies), can be completed without the calibration steps. The Automatic Learning Mode utilizes artificial intelligence (AI), software algorithms and other software to perform this operation. In this embodiment, a single sensor (e.g. flow rate sensor) 150, with optional pressure sensor(s) 65, optional acoustic se or(s), and/or temperature sensor(s) 93 can be located within or near the water meter and leak detection system 10 (126 shown in
For example, after a period of time (historical analysis), Automatic Sensor Leaning Mode using AI, software algorithms and other software can monitor a washing machine's range of water flow used and records the water use duration periods, water flow rate patterns (water flow rates for washing machine cycles and variations of water flow rates over time). The Automatic Sensor Learning Mode can use optional pressure sensor(s) for determining variations in pressure patterns and can use optional acoustic sensor(s) for identifying water valve movement and sounds when opening and closing and any vibrations during fully open valve with water flowing through the valve. In another example, when a toilet is flushed, the Automatic Sensor Leaning Mode software recognizes the toilet water use pattern. If a bathroom faucet is turned on for hand washing, the software can identify the combination pattern of the toilet filling and the faucet water use. In this case an optional acoustic sensor can identify and differentiate the toilet and bathroom faucet water valves to more accurately monitor the water used by these different waters use devices at the public or private property or structure. The Automatic Sensor Leaning Mode software can analyze, record, and store actual independent flow rates, variation of flow rate over time, duration periods, temporal activities, optionally variations in pressure patterns (e.g. rate of flow at onset of water flow and rate of flow when turned off, and any variations during water flow duration, and optional acoustic sensor observing water valve characteristics to assign the signature or pattern of water use for the toilet and bathroom faucet.
The water meter and leak detection system's water leak detection and monitoring capability can use wireless technology such as LoRa, WIMAX, 6LoWPAN, UNB, Wi-Fi/Wi-Fi3 (with WiFi extenders), Cellular 3GPP, and/or LTE-M and 5G, Bluetooth and BLE, ZigBee, Z-wave or similar wireless protocols or other communication technologies using the TCP/IP or other OSI technology to transmit an alarm or message to notify of leak condition(s) at a private or public property(ies). Leak notification can be provided via call to a registered or designated cell or smart phone, computer, or similar apparatus or the water meter and leak detection system can send an alarm(s) or message(s) to a governing utility or municipality.
Analog sensors with analog data can be amplified by a circuit and connected to the CPU, microprocessor and/or microcontroller 84 through the use of an analog-to-digital module(s). Digital sensors can communicate with the CPU, microprocessor and/or microcontroller 84 directly.
The remote display devices 46, 52, 54 and 400 can communicate wirelessly are located remotely from the water sensor(s), CPU, microprocessor and/or microcontroller 84, electrical circuitry, and data transfer technology 83. The water meter and leak detection system 10, 126, 200 uses various wireless technologies. Examples include Bluetooth modules (using the 2.4 GHz band as Wi-Fi) such as the RN-41 Bluetooth modules available from Roving Networks in Los Gatos, Calif.; the KC-41, KC 11.4, KC-5100, KC-216 or KC-225 data serial modules from KC Wireless in Tempe Ariz.; and the BT-21 module from Amp'ed RF wireless solutions in San Jose, Calif. Wi-Fi examples include the Photon manufactured by Particle, Inc. and numerous other Wi-Fi products. Cellular technology examples include the Electron manufactured by Particle, Inc. numerous other cellular products. Wireless protocols that can be utilized with the water meter and leak detection system include, but are not limited to IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and IEEE 802.11n modulation techniques. An example of the North America 915 MHz frequency is the wireless long range and low power technology known as “LoRa”, which is marketed by many manufactures such as HopeRF (RFM95 W-915S2) and Semetech (SX1276). LoRa can be used with the collection node and the communication hub of the water meter and leak detection system 10, 126, 200. LoRa is a low power wide area network specification intended for wireless battery operation. LoRa includes key requirements of Internet of Things (IoT) such as secure bi-directional communication, mobility, and localization services. Texas Instruments manufactures a competing technology known as the sub-1 GHz with 15.4-star networks (CC1125 or CC1310 device). NB-IoT chipsets and being developed by manufactures such as Snapdragon and Intel, just name a few. Other wireless protocols that can be utilized with the water meter and leak detection system are ZigBee, Z-Wave and IEE 802.15.4 modulation technology. Examples of cellular technology and protocols include CDMA and GSM and numerous other cellular protocols. The Applicant recognizes there are numerous wireless protocols and technologies that have been developed and, although not specifically listed herein, could be utilized with the present invention for data transfer purposes.
To increase wireless range and provide compatibility with wireless routers or corporate networks, the water meter and leak detection system 10 (126 shown in
The water meter collection node's electric circuitry includes a generally low power long-range wireless radio and the water meter collection node's power source can be AC or DC voltage, battery, and/or super capacitors. The battery and/or super capacitors can be supplemented with a water turbine electric generator. The water meter collection node communicates wirelessly with the communication hub which can extend the range of wireless technology. The communication hub has a CPU/microprocessor, electrical circuitry with a generally a first long-range wireless radio and a second Wi-Fi radio, and a power source (battery or AC or DC voltage). In one embodiment, the communication hub has a first wireless long-range LoRa, Sigfox, UNB, NB-IoT, 6LoWPAN, or WiMAX radio 103 that communicates with the water meter collection node (that has a corresponding LoRa, Sigfox, UNB, NB-IoT, 6LoWPAN or WiMAX radio). The communication hub, which has programmed instructions for processing the water flow data from the first long-range radio into a second wireless radio that communicates with a wireless router, or RF technology) and cellular radio that communicates with a private or public corporate network. The communication hub can alternately be hard wired to the router and then the Wi-Fi radio is not a necessary component of the electrical circuitry. The water meter collection node can communicate with one or more water meters collection nodes and/or with one or more communication hubs (using mesh technology and/or point-to-point technology). The communication hub can wireless communicate with one or more water meter collection nodes and/or with one or more communication hubs (using mesh technology and/or point-to-point technology).
The wireless or wire data transfer can be connected to the Internet using the IP or DHCP protocols whereby the water parameter data can be monitored remotely over the Internet using a software program(s) designed to record, display, analyze and/or audit the data. Data access would likely require server log on to perform query and obtain response.
Some wireless routers support a form of point-to-point or bridging operation which could be used to transfer water parameter data from the water meter collection node to a communication hub. Other proprietary protocols can be used with the Water meter and leak detection system 10 (126 shown in
While currently the 430 MHz and 900M1 Hz frequencies are commonly used in the United States, it is anticipated by the Applicants that other frequencies could be used for water use and water quality information or data communication transfers.
Cell phones receive and transmit electromagnetic waves that exist between 800 and 2400 megahertz and the most popular protocols are CDMA and W-CDMA, GSM, 3GPP, LTE-M and 5G, EDGE, HSPA and other generations.
Many newer internet protocols have been developed commonly known as an application programming interface (API). An A.PI for website usage is a code that allows two software programs to efficiently communicate with each other. The API defines a well organized and resourceful way for a programmer or developer to write software instructions in the program separate from an operating system or other application. One such API is the RestAPI system which aims for fast performance, standardization, reliability, and with the ability to grow, by re-using components that can be managed and updated without affecting the commercial system. A RestAPI uses HTTP requests to GET, PUT, POST and/or DELETE data or send control signals. A RestAPI, also referred to as a RESTful web service, is based on the representational state transfer (REST) technology, an architectural style and approach that has communications often used in web service development and communications between mobile device APPs and computer servers. REST technology is generally preferred API protocol because it utilizes less bandwidth, making it more suitable for internet and IoT usage. With cloud-company services on the rise, APIs are being developed to facilitate communication with web services mobile APPs. REST is a logical choice for building APIs that allow users to connect and interact with Cloud services.
RestAPI has a uniform interface, which serves as the interface between water meter data generated and transferred to remote computers, cell phones and computers with mobile APPs or stations with computer programs and remotely located computer servers. The uniform interface simplifies and decouples the REST architecture, which enables the device APPs or station computer programs and remotely located computer servers to evolve independently. The main guiding principles of the uniform interface are described below.
First by using resources for identified using Uniform Resource Identifiers (URIs) as resource identifiers. The identifiers are separated from the representations that are returned to the client. The commercial or private server does not transfer data directly from the database, but rather, utilizes HTML, XML or JSON code that is designed to represent database records expressed in variable width character encoding, depending on the details of the structured query language (SQL) request and the server implementation.
Second, a representation of a resource, including any metadata attached, and the software will verify that it has enough security information to modify or delete the resource on the server only under proper server permissions.
Then, a third process includes that each message includes enough information to describe how to process the message invoking specified content by an Internet media type. Responses also explicitly indicate their cache-ability.
On the fourth process the delivery of data or information utilizes SQL or non-SQL parameters, body content or headers, and requested URI for transmission communications. Computer or servers respond via body content, response codes, and response headers to the request. Hypermedia as the Engine of Application State (HATEOAS) links are contained in the returned body (or headers) to supply the URI for retrieval of the database objects from a remote computer server(s) with database(s).
Stateless of the REST architectural style and associated RestAPI protocol handles any sent requests, whether as part of the URI, query-string SQL or non-SQL parameters, body content, or headers. The URI uniquely identifies the resource and the body content contains the state (or state change) of the resource. After server/computer processes the request, the appropriate state (or the piece(s) of state that matter) is communicated back to the requesting mobile APP or computer program via headers, status, and response body.
The RestAPI protocol includes a properly managed caching that facilitates client-server transfers o water meter data, and communication with cell phone APPs, station programs and remotely located server interactions, further improving scalability and performance. Since remote computers and servers are not directly concerned with the water meter, computer and servers can be scalable. Computers and servers may be replaced, process operating system or software updates, and/or developed independently and whereby the RestAPI interface is maintained and unaltered.
The LoRa open specification create a low power, wide area LoRa technology network that is designed to wirelessly connect battery operated devices and sensors to the internet. The LoRa protocol utilizes the unlicensed radio spectrum in the Industrial, Scientific and Medical (ISM) band. The specification defined the device/sensor to infrastructure of the LoRa physical layer (OSI) and provides seamless interoperability between devices, sensors APPs and computers.

The water meter and leak detection system 10 (126 shown in
There are several important security techniques that taken as a whole, or in part, function to meet the objectives to, including authentication, integrity, encryption and non-repudiation that provide secure communications.
Several current security techniques that utilize public key cryptography are the Public Key Infrastructure (PKI), the Public Key Encryption (PKE) and the Digital Signature protocols. PKI enables digital certificates to be used to electronically identify an individual or an organization. A PKI requires a certificate authority (CA) that issues and verifies digital certificates and can utilize a registration authority (RA) that acts as the verifier of the CA when a new digital certificate is issued. PKE is a message or command signal that is encrypted with a recipient's public key. The message cannot be decrypted by any individual or machine that does not possess the matching private key. PKE is a security protocol that is used to maintain confidentiality, Similarly, Digital signatures are also utilized with key pair technology, in association with authentication, integrity and non-repudiation confidentiality techniques. In practice, when a user transmits a message or signal or data with a digital signature, the message or signal includes a one-way hash prior to transmission, and the recipient uses the sender's public key to decrypt the hash and verify the digital signature. PKI, PKE, and digital signers are currently being supplemented with two factor authentication that utilizes a confirmation protocol after password input with a follow up email, phone call, or utilizing a authenticator number scheme. Furthermore the PKI, PKE and digital signature techniques might become archaic when block chain technology becomes more generally adopted.
Various encryption algorithms such as include the original RSA algorithm, Advanced Encryption Standard (AES), Data Encryption Standard (DES) and Triple DES.
Secure technologies include the Secure Sockets Layer (“SSL”) which creates a secure connection between two communicating programs or applications. SSL is a standard security technology for establishing an encrypted link between a server and a client-typically a web server and a mail server or a mail client (e.g., Gmail). The SSL protocol are commonly utilized by web browsers and web servers in conjunction with HTTP protocol to perform cryptographically secure web transactions.
Another security technology is the Internet Protocol Security (“IPSec”) which protects internet protocol traffic across the Internet and is particularly useful for implementing VPNs that utilized tunnel and encryption techniques. IPSec originally utilized an IP authentication header. IP encapsulating security payload was an optional packed header that can provide superior confidentiality through encryption of the packet. Point-to-Point Tunneling Protocol (“PPTP”) is another secure protocol that allows entities to extend their local network through private “tunnels” over the Internet. Layer Two Tunneling Protocol (“L2TP) is an extension of the PPTP protocol.
A Media Access Control Address (“MAC Address”) is a unique number assigned to a network interface controller for communications with the data link layer of the Open Systems Interconnection Model (OSI Model.) The MAC address is appended to a digital message and provides authentication and integrity for the message.
A further security protocol, the extensible Markup Language (XML) Signature associates a cryptographic signature value with Web resources using XML markup, XML signature also provides for the signing of XML data. Javascript object notation (JSON} has become more popular alternative to XML for various reasons, for example, JSON is less verbose than XML which uses more words than necessary and JSON is faster processing whereas XML software is generally slow and cumbersome.

In an alternate embodiment, the encrypted data is transmitted optionally to a local router/server and then across the Internet or cell tower technology, or via directly to a public or private network as it has been described herein.

In the LoRa or WiMAX (or Ultra Narrow Band (UNB), 6LoWPAN, standard WiFi and WiFi3 with Wi-Fi extenders) 103 wireless communication, the current marketed routers would have to be modified to receive the LoRa, WiMAX (UNB, 6LoWPAN) wireless duplex transmission.

A preset alarm might include visual reference, for example, an in-operative condition, broken sensor, low power source, backward water flow, and some default limits.

Because the water meter and leak detection system (126 shown in
Not shown but could be included with the water meter and leak detection system (126 shown in
As illustrated in
In general, a sensor is type of transducer that is generally paired with an indicator display. Most sensors are electrical or electronic, although other types exist (e.g. mechanical).
Technological progress allows for more and more to be manufactured on the microscopic scale as micro-sensors using MEMS technology. In most cases a micro-sensor reaches a significantly higher speed and sensitivity compared with macroscopic approaches.
There are many types of sensors that can be used with the present invention. Since a significant small change involves an exchange of energy, sensors can be classified according to the type of energy transfer that they detect. For measuring or monitoring the temperature of the water flowing through the water meter and leak detection system 10, 126, the use of various thermocouples or thermistor sensors 70 as depicted in
A thermistor is a type of resistor used to measure temperature changes, relying on the change in its resistance with changing temperature. Thermistors can be classified into two types depending on the sign of k. If k is positive, the resistance increases with increasing temperature. If is negative, the resistance decreases with in decreasing temperature, and the device is called a negative temperature coefficient (NTC) thermistor.
It is anticipated by the Applicant that various types of thermocouples or thermistors can be used for the present invention. It is not important what type of thermocouple or thermistor is utilized for monitoring the water supply lines except that it is accurate for the appropriate temperature range monitored or measured.
To monitor or measure the flow rate of the water being delivered by the water supply line various flow measuring technologies are applicable to the present invention water meter.
The flow sensor 105 can be fabricated from pressure sensor technology. There are three general types of pressure sensors and each offers advantages and disadvantages for applied pressure monitoring operations. The three types are 1) absolute, pressure, 2) differential pressure measurement and 3) gauge pressure measurement. Absolute pressure references pressure in in a perfect vacuum. Differential pressure measurement compares the difference between two applied pressures. Gauge pressure measurement is a subtype of differential pressure measurement and compares the ambient atmospheric to the applied pressure. Pressure sensors can be utilized with the present invention for accurate monitoring or small leaks. Examples of pressure sensors are the pressure transducer (sensor) TI2C marketed by Anfield and for a differential sensor the Motorola MPX5700 series. Pressure sensors can be particularly useful in measuring small leaks by shutting of the water supply line and then monitoring the pressure loss over time.
There is also a category of pressure sensors that are designed to measure in a dynamic mode for capturing very high-speed changes in pressure. These sensors are commonly manufactured out of piezoelectric materials like quartz. Pressure sensors can perform as a flow rate sensor (e.g. the differential pressure gauges Motorola MPX5700) or be sensitive types that can sense pressure waves and pressure changes for water pattern analysis. One particular use would be to use the pressure sensor (e.g. ceramic capacitive pressure sensor) to monitor the pressure of a private or public property(ies) after a water control valve has turned off the water supply. The pressure sensor can then measure the decay in pressure reads to observe and indicate small leaks (dripping faucet).
Acoustic sensors are advancing to the point where they can monitor water flow and pressure readings that are approaching accurate quantifiable results. But acoustic sensor original function is to listen and record water valve noises and vibration frequencies. It is anticipated that all water devices have a valve with a unique “open” and “close” noise and vibration frequency. An acoustic sensor can therefore be significantly useful for identifying various water devices such as showers, washing machines, toilets, irrigation valves, bathroom and kitchen faucets, and other water fixtures and appliances. As each of the water use devices is used, the acoustic sensor can specifically identify the particular water use device. This is useful to characterizing water use as shown n
In addition, various flow measuring technologies can be utilized as the flow sensor 105. In general, a flow sensor is a device for sensing the rate of fluid flow. Typically, a flow sensor is the sensing element used in a flow meter. There are various kinds of flow meters, including invasive (sensor movement within the tube or pipe) that have a vane, wheel, or turbine structure that is pushed by the fluid, and can drive a rotary potentiometer, or other similar device to monitor the flow rate. Flow meters can use a displacement piston, pushing it against a calibrated spring is a qualitative method and can only be used to show if the flow is on or off. Non-invasive flow rate sensors (sensor outside of the pipe) can be time-based or Doppler-based ultrasonic technology, or magnetic type flow sensors for measuring and recording water flowing through a tube or pipe.
The Pelton wheel turbine, paddle wheel and axial turbine translates the mechanical action of the specifically shaped objects rotating in the liquid flow around an axis that is translated into a user-readable rate of flow magnetic or optical monitoring technology. To function adequately, the specifically shaped object or paddle must be at least partially inserted into the water flow.
In addition, non-invasive (outside the water flow pathway) magnetic and ultrasound flow meters can be utilized with the present invention to function as the flow sensor 105. Modern innovations in the measurement of flow rate incorporate electronic circuitry to correct for varying pressure and temperature. The magnetic flow meter, utilizes a magnetic field is applied to a tubular structure that has electrical insulating properties.
The ultrasonic flow meters can measure water flow using two methods; transit time and 2) doppler shift. Both methods are possible by use of modern electronics. The transit time method measures the difference of the transit time of ultrasonic pulses propagating in and against flow direction. This time difference is a measured for the average velocity of the water flowing through a specified path by the ultrasonic beam. The Doppler shift method monitors water flow rate by passing an ultrasonic beam through the water pipe, bouncing the beam off a reflective plate that reverses the direction of the beam, such that the flow rate of water flow can be estimated. The speed of transmission is affected by the movement of water in the pipe and by comparing the time taken to complete the cycle upstream versus downstream the flow of water through the pipe can be measured. The difference between the two speeds is a measure of true flow rate.
Fluid flow rate can be measured using monochromatic laser diode. The laser probe is inserted into a water stream and turned on, whereby the laser light scatters, and, a portion is reflected back to the probe. The signal is then electronically processed to calculate flow rate within the water pipe. The laser diode flow meter is more useful for relative rather than absolute measurements.
Multi-jet meters, positive displacement meter, single jet meters, pressure sensors, magnetic, ultrasound and Coriolis flow meters can be utilized with the present invention to function as the flow sensor 105.
In addition, as shown in

The display means 114, 116, and 118 can be programmed to display one or more parameters in a visual means that can utilize analog, character or digital display technology, or combination of the different display technology. Information obtained from the appropriate sensor monitoring or measuring the water parameters such as temperature, date/time, total volume over time, and flow rate can be displayed in an appropriate format on the display means. For example, when a sensor is monitoring or measuring the rate of water flowing from a water source and through the water meter and leak detection system 10, 126, the display means could show any flow between 0.1 gal/min (0.1 liters/min) to many thousands of gals/day.

This protects the more expensive water meter and leak detection system 10, 126, 200 and private and public building water distribution piping by sacrificing the less expensive and easy to install frost/freeze plug. The optional frost/freeze plug technology is typically used in outside underground pits or poorly heated garages or utility rooms. In some extraordinary freezing situations, the optional frost/freeze plug can be incorporated with a draining mechanism or system (not shown) that allows the water to passively drain from the private or public property(ies) water pipes or forcefully removes the water from the water pipes with a power system. Another method to protect from freezing conditions is to use a three-way control valve whereby the third port drains water from the private or public property(ies). Software will be designed to position the three-way control valve in all three positions. And it is anticipated that in these extraordinary freezing situations, the draining mechanism or system can also replace the water in the water pipes with air, nitrogen or other gas/liquid that have low freezing points and non-toxic conditions, that can withstand the freezing conditions to minimize damage to the water pipes. Furthermore, be communicating with a home router, the water meter and leak detection system 10, 126, 200 can communicate with intelligent thermostats sending a signal to turn on the residential or corporation heat to a temperature that will inhibit freezing water in the residential and corporation interior water pipes.

A display means 211 can display calendar information, such as the date and current time (12 hr. or 24 hr. format). The water meter collection node 200 can be programmed using a wire or wireless technology such as an alarm system or use touch screen button technology on the display. The display and display housing must be able to sustain capability in outdoor wet and/or hot/freezing conditions. The display 211 can have a background light that is used for various purposes, for example, for providing better lighting conditions or changing color e.g. from green to red, to display an alarming condition. The display can utilize touch screen technology.
One of the key features of the water meter and leak detection system 10, 126, 200 is that it has a convenient means that facilitates activation and/or deactivation of the water flow from the main water supply when a private or public property(ies) facility or building when it becomes vacated or unsupervised. An vacated or unsupervised private or public property(ies) facility or building can utilized a passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared light radiating from objects in its field of view. The PIR sensor can communicate wired or wirelessly with a router that sends a signal to the water meter and leak detection system 10, 126, 200. Shown in
For leak detection capability is would be, preferred that the water meter and leak detection system 10, 126, 200 with a water shut-off/on mechanism 310 include programming instructions with a timing circuit to allow a user to program a defined time schedule. In this manner, the private or public property(ies) owner may simply establish that the water supply will be shut, off or blocked during non-working hours, during a vacation, and/or during sleeping hours. The scheduling could be a daily, weekly, monthly or annual or on a water use basis. The Programming of the timing schedule could be input into the CPU of the water meter collection node or the communication huh (or receiving station) via various methods, e.g. wireless or wired communication with a computer with appropriate software, using the remote controller using touch screen technology on the display means, or cell phone, smart phones, or similar electronic mobile apparatus 400. The vacation schedule can even be programmed, to turn on for the irrigation schedule to water the home or corporate plants, shrubbery or ground cover. This modified programming will turn off the supply water during a vacation and automatically turn on the supply water when the irrigation controlling is programmed to water the yard or area, e.g. 6-8 a.m. on Monday, Wednesday and Friday.

There are large cloud-computing companies with several computer server farms around the world that supplant the independent comprehensive internet infrastructure and communication network. Companies like Amazon®, Microsoft®, Oracle® and Google® have all built a significant quantity of computing infrastructure. Their data centers are vastly bigger, and significantly more efficient, than those operated by or could be built by most other independent companies. The cloud-computing companies with their worldwide server farms allow for scalable and redundant data storage capabilities (Redundant Array of Independent Disks or RAID technology). The large cloud-computer companies can temporarily extend or customize the functionality for a client by transferring logic to it that it can execute. Examples of this may include compiled components such as Java applets and client-side scripts such as JavaScript. Complying with these constraints, and thus conforming to the REST architectural style (REST an acronym for REpresentational State Transfer), which will enable any kind of distributed hypermedia system to have desirable emergent properties, such as performance, scalability, simplicity, modifiability, visibility, portability and reliability (RestAPI). These large companies are presently marketing and rented out their computing capacity to developers and companies around the world. The developer or company doesn't have to incur the capital expense associated with designing network connectivity system, employing various Information technology (IT) professionals, purchasing the necessary computers and servers, developing the custom and non-custom software and conducting the significant maintenance procedures.
A programmer/developer or a company simply pays for the cloud-computing services. Using the cloud-computing services provide the developer and company access to fundamentally unlimited computing power marketed by the cloud computing companies without must incur the expenses for developing and maintaining a private or corporate computer infrastructure.
There are various services, divided into certain categories, that are provided by the cloud computing companies. Infrastructure as a Service, or “IaaS,” is the most basic layer of cloud computing. It provides customers with virtual servers and database storage and Internet of Things (IoT) sensor communication and access. Platform as a Service, or “PaaS,” which is the set of application tools and services that make it easier for developers and IT professionals to build applications without the capital expense of purchasing software for application development. Software as a Service, or SaaS, which refers to applications that run in the cloud like Microsoft's Office 365, Google's G Suite and Salesforce's products for sales and marketing.
The plan for a cloud-computing companies is to make their services indispensable to both independent software developers and small, medium and large companies. Customers might venture into cloud computing with a single software application (APP) but as their businesses grow, their cloud-computer needs increase and the cloud-computing service companies are expecting that their cloud usage and revenue will increase. Amazons has increased their presence in the cloud industry, by sacrificing short term profits to enhance the customer experience and maximize long-term gain. The more customers a cloud platform provider contracts with, the more servers and serving farms under their control can be developed. And the more servers the cloud-computing companies have, the better they can take advantage of economies of scale and offer customers lower prices for more robust features, including appeal to large enterprises. The efforts to market cloud-computing services supports that the near future of internet infrastructures and communication networks will increasing be controlled and maintained by the large cloud-computing companies.
Specific communication protocols are becoming important to interface between the cloud-computing companies and the company's local or cloud database for computer, cell phone, smart phone and similar apparatus, smart internet TVs, smart central hub listening and speaker devices, and home control systems, access to acquire requested data (e.g. SQL database requests) and perform instructional activities (turn on/off water). Of these protocols, the Representational state transfer or RestAPI (or REST API), SOAP API, Java API or XML API seem to be appropriate.
Once a user sets up a service, an activation application 494 delivers a first display to the user on either a display means of a remote computer, cell phone, smart phone, mobile phone or other electronic apparatus 400, smart Internet TVs, smart central hub listening and speaker devices, and home control systems, on the water meter and leak detection system 200 and/or on a display means on the remote devices 480. This pairing technology or other application secure means associates a new user with a purchased or installed remote device and the water meter and leak detection system 10, 126, 200.
