FIELD OF THE INVENTION
The present invention relates to a water metering system with piggy backed e-commerce.
BACKGROUND TO THE INVENTION
In order to better control the use of fresh water, water meters have been installed in buildings and residences. One drawback is that such prior art water meters are mechanical and may only be read locally by via a dial or attaching an appropriate reader. Installation of new networked meters is expensive for both the utilities, who wish to have an accurate view of actual consumption to provide detailed, and users who better wish to understand their own consumption as well as the costs involved.
SUMMARY OF THE INVENTION
In order to address the above, there is provided a water metering system with piggy backed e-commerce. The system comprises a water utility comprising a water consumption data collection server comprising circuitry for communicating via a wide area network, an e-commerce system selling at least one product and comprising circuitry for communicating via the wide area network, a water utility infrastructure comprising a water mains supplying water under pressure to a plurality of locations of water consumption, a plurality water meters, one of the water meters attached along the water mains at each of the locations of water consumption, each of the water meters comprising a meter for measuring water consumption, circuitry for communicating via a near field network, circuitry for communicating via the wide area network, a controller and a memory for storing the measured water consumption, wherein the measured water consumption is transferred from time to time to the water consumption data collection server via the wide area network, and a plurality of hand held user devices each comprising circuitry for communicating via the wide area network and an application for communicating with an accessible one of the water meters using the wide area network. Using the wide area network, the application retrieves the measured water consumption of the accessible water meter and accesses the e-commerce system via the wide area network, the application displaying the retrieved water consumption together with the at least one product, and further wherein the at least one product may be purchased from the e-commerce system using the application.
There is also provided a water meter for metering water flowing from a water main to a water distribution system and communicating with a water consumption data collection server via a wide area network. The water meter comprises a solar powered power source, an inlet connected to the water mains, an outlet connected to the distribution system, an impeller positioned between the inlet and the outlet wherein a speed of rotation of the impellor varies as a function of a water flow rate between the inlet and the outlet, a sensor for measuring the speed of rotation, circuitry for communicating via the wide area network, and circuitry for converting the speed of rotation into a measured water consumption wherein the measured water consumption is transferred from time to time to the water consumption data collection server via the wide area network.

A water main 12 provides water under pressure to a plurality of water consumers 14 at a location of water consumption, such as a residence, building or business or the like (not shown) via a respective water meter 16. Each water meter may comprise network circuitry 18, for example a nearfield network such as RF or Bluetooth and/or WiFi, including an associated antenna 20 for communicating via an RF/Bluetooth/WiFi LAN 22 and wide area network circuitry 24 for communicating via a Wide Area Network (WAN) 26 such as the internet or like. In this regard, the wide area network circuitry can include for example a cellular modem (not shown) for accessing the wide area network 26 via a GSM/GPRS/GPS type connection. In an alternative embodiment, access to the WAN 26 is provided to a plurality of water meters (for example in multi-unit housing or the like) via the RF/Bluetooth/WiFi LAN 22 and a main gateway 28.
Still referring to FIG. 1, a water utility 30 comprises a water consumption data collection server and a data store 32 and wide area network circuitry 34 for communicating via the WAN 26 is interconnected to the water meters 16 via the WAN 26, to which are also attached at least one e-commerce system 36, also comprising wide area network circuitry 38 for communicating via the WAN 26, and selling products (not shown). A plurality of hand held devices 40, such as a smartphone or tablet or the like, each executing an application 42, communicate with an accessible one of the water meters 16 via the WAN 26.
Still referring to FIG. 1, the water utility 30 collects from time to time data on water consumption from the water meter 16 via the WAN 26. This data may be stored in the data store 32 for analysis purposes and billing and the like. Additionally, a user may access a local water meter 16 using a suitably equipped hand held device 40 including the application 42 and via the WAN 26 to retrieve information on local water consumption from the water meter 16.
Referring now to FIGS. 2A and 2B, the water meter 16 comprises a housing comprising a lower part 44 and an upper part 46 which is secured to the lower part 44 by a plurality of lock screws 48. The water meter 16 illustratively further comprises an inlet 50 for connection to a water supply under pressure (not shown), an outlet 52 for connection to the water distribution piping of a building or the like (also not shown), an antenna 54 and a power source such as a solar panel 56. In an alternative embodiment, and as will be discussed in more detail below, the water meter 16 can be powered by an external source such as mains current or the like and using a suitable adaptor.
Referring now to FIG. 3 in addition to FIGS. 2A and 2B, a hollow space 58 in the lower part 46 of the water meter 16 receives a water flow directing insert 60 and an impeller assembly 62 therein. The water flow directing insert 60 comprises a plurality of channels 64 which guide water flowing between the inlet 40 and outlet 52 over the impeller 62 and such that the impeller assembly 62 rotates. The impeller assembly 62 comprises a collar 66 which rotates about an impeller axis therewith and into which a magnet 68 is mounted of axis. The water flow directing insert 60 and impeller assembly 62 are sealed within the hollow space 58 by a gasket 70 and an intermediate cover 72. The intermediate cover 72 and gasket 70 are secured to the lower part 46 by a plurality of bolts 74 which are inserted through respective ones of a plurality of bores 76 in the intermediate cover 72 and engage receptive ones of a plurality of threaded bores 78 in the lower part 46. Illustratively a strainer 80 is inserted into the inlet 50 to capture dirt and the like which might otherwise for example foul the impeller 62 assembly. Additionally, a flow check valve 82 can be provided on the outlet to ensure that the water meter 16 will not operate if incorrectly attached between the water mains and distribution network (both not shown).
Still referring to FIG. 3, the upper part 48 of the water meter 16 covers a printed circuit board (PCB) 84 which is secured to the intermediate cover 72 by a plurality of screws or the like (not shown) and on which, as will be discussed in more detail below, electronics 86 are placed.
