Pumps can be used to transfer liquid from a source to a target delivery location, such as transferring fuel from a storage vessel to a target vehicle. Often, when transferring fluids, such as fuels, from a storage vessel to a receiving vehicle or container, a metering apparatus is used to identify the amount of liquid transferred in order to maintain appropriate records. Typical meters measure the amount (e.g., volume, weight, etc.) of liquid passing through a transfer component (e.g., hose, pipe, etc.), and display the measured amount for an operator to record.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key factors or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
One or more techniques and/or systems are disclosed for providing for improved fluid transfer information (e.g., transactional and/or metering information) collection and management. As an example, a system may utilize scannable codes to collect fluid transfer information, mitigating the use of printable tickets, radio wave or cellular data communication, or manual collection, while improving security. A metering register device can be connected to a fluid flow meter to collect flow, fluidic volume or mass information from the meter, for example, as well as collecting information associated with fluid transfer, such as data input by a user or captured from connected hardware. Upon completion of a fluid transfer event, such as aircraft refueling or other fluid transfer applications, data associated with the transfer event, such as customer, sale number, quantity, product type, conditions, operator, time, price, and product characteristics such as fuel quality, density, additives, inventory levels, system pressures, etc., can be converted into a scannable code, such as a QR code and displayed on a display screen. The scannable code can be captured by a portable device, stored, and later transferred to a back end data management system.
In one implementation of a system for collecting and transferring fluid transfer data can comprise a fluid flow register that receives fluid flow information from a fluid flow meter for a fluid transfer event, and collects data associated with the fluid transfer event. Further, the example system can comprise a scannable code generator that generates a scannable code comprising data indicative of the fluid flow information and the collected data. Additionally, a display screen can be used to display the generated, scannable code. A portable scanning device can be used to scan or capture the scannable code that is displayed on the display screen. The captured code or the data indicative of the fluid flow information and the collected data can be stored, viewed, and analyzed locally. The portable scanning device can transfer the scannable code or the data indicative of the fluid flow information and the collected data to a remote fluid transfer data management system or accounting system.
To the accomplishment of the foregoing and related ends, the following description and annexed drawings set forth certain illustrative aspects and implementations. These are indicative of but a few of the various ways in which one or more aspects may be employed. Other aspects, advantages and novel features of the disclosure will become apparent from the following detailed description when considered in conjunction with the annexed drawings.
The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are generally used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the claimed subject matter. It may be evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, structures and devices are shown in block diagram form in order to facilitate describing the claimed subject matter.
A system can be devised for metering, recording and managing liquid transfer data, such as fueling of aircraft, for example. As an example, aircraft fueling (e.g., and other vehicle fueling) may be performed in a commercial setting (e.g., not a consumer point of sale), where the amount of fuel transferred is metered, records of fuel transfers are maintained, and invoicing and/or inventories can be managed. At times, for example, the data associated with the vehicle fueling (e.g., amount, type, timing, quality, etc.) may be sensitive to the users, such that it may be desirable to keep the information from third parties while also mitigating translational errors, or manipulation by reporting operator or any third party, whether intentional or otherwise.
In one aspect, a system may be devised that allows for increased data security, while also allowing for improved data collection accuracy, along with improved data storage and management. In one implementation, in this aspect, the liquid transfer data may be transferred from a liquid metering apparatus to a data collection device using an optical scanning operation. As one example, upon completion of liquid transfer, the metering apparatus can generate an optical code that is indicative of the data associated with the liquid transfer event, and display that code on a display screen. Further, in this example, an operator can use a portable device to scan the displayed code, to transfer the code to the handheld device. In this way, for example, the displayed code comprising information indicative of the liquid transfer data can be merely transferred though direct optical scanning.
As one illustrative example, aircraft fueling involves transferring aviation fuel from a storage tank (e.g., mobile or fixed) to the fuel tank(s) of the target aircraft. Typical fuel transfer operations can involve open nozzle refueling, such as over-the-wing refueling, or pressure refueling, such as using a sealed, pressurized fueling line. Either way, for example, the fuel is pumped from the storage vessel to the aircraft tank(s), and is typically metered to determine how much fuel is transferred. Over-the-wing refueling involves placing a fueling nozzle in a fueling opening (e.g., typically on top of the wing), much like typical automobile fueling, and operating the pump to fill the tank(s) through gravity. Pressure refueling involves securing the fueling line to a fueling opening (e.g., typically under the wing), and sealing it in place. The pump is operated and fuel is forced into the tank(s) under pressure. It should be noted that the techniques and systems, described herein, may be utilized with other fluid transfer operations, in other industries, such as liquefied petroleum gas (LPG) in a variety of industries and settings, ground vehicle fueling, fleet vehicle fueling, and others.
Typically, for aircraft refueling, a fuel meter (e.g., flow meter) is disposed in-line between the storage vessel and the aircraft fuel tank. Often, a pumping vehicle (e.g., dispenser unit or other apparatus) is used to transfer fuel from a stationary tank, from an underground hydrant system, or from fuel stored on-board the vehicle. In one example, the refueling vehicle may comprise a pumping unit and a metering unit, amongst other systems. As an example, an aviation fuel measuring device may comprise a positive displacement meter; and other examples may include amplified turbine, electromagnetic, and mass flowmeters. A positive displacement flow meter measures a flow rate of a volume, or volumetric flow rate, of a fluid moving through known, metered volumes. A number of known volumes that pass through a chamber in the meter identifies the fluid volume; and the rate of revolution of gears or reciprocating parts identifies the flow rate. As one example, a meter may comprise a housing in which a plurality (e.g., three) synchronized rotors turn as a result of fluid flow.
In one implementation, the meter may comprise a Weights and Measures-approved (e.g., approved by a governmental or industry agencies for targeted use, accuracy, etc.) mechanical or electronic register, along with ticket printer, and/or control systems, which may be used for truck-mounted or fixed-site meter applications. That is, for example, a site that is without electrical power may utilize a mechanical system that relies on the movement of the fluid through the system to operate the register, and/or control systems. As another example, at a site powered with electricity, an electronic register may be used, along with ticket printing, and/or control systems. As an example, both technologies can provide recording functions for totalizing, inventory control, billing, batching, and ticketing.
In one implementation, a mechanical register may be used in a variety of mobile and fixed-site applications, such as applications without electrical power. In another implementation, an electronic register coupled with the flow meter can provide highly accurate metering over various ranges of flow rates. Further, such a register can provide enhanced functions including: automated data collection (e.g., date, time, product selection, delivery quantity, and more), on-site ticket generation, meter linearization (e.g., error correction), electronic temperature volume compensation, and/or improved security. As an example, security may be of special concern in applications where data concerning the liquid transfer is proprietary and/or of special importance as a valued secret (e.g., government, military, trade secrets, etc.). For example, it may be desirable to keep secret the type and amount (e.g., and other data) of fuel transferred to a military aircraft during refueling.
In one implementation, an electronic flow meter may comprise a microprocessor-based electronic meter register that is configured to the properties of the metered liquid, and interfaces with the electronic components of the meter system (e.g., and external components such as pumps, injectors, and shutdown devices), and also performs Weights & Measures approved custody transfer actions. Some electronic flow meters can comprise a display screen used for data output and user input.
In one implementation, the flow meter may comprise, or be comprised in, a system for data capture and data management. As an example, such as system may be able to capture transaction data at the fueling point, and send the data to a back end portion (e.g., such as in an office or other third party), to prepare the data for further use, such as inventory, invoicing, etc. As an example, fueling data can be automatically captured, and the data can be transferred to a back end system for processing. As an example, upon fueling completion, a user/operator may print out a ticket that comprises information indicative of the fueling operation. Further, in this example, the fueling data may be transferred (e.g., wired or wirelessly) to a data management system, such as in the back end of a fueling management system.
In one implementation, the flow meter may comprise programming, such as an application, that converts the liquid transfer data (e.g., fueling data) into a scannable code, such as a bar code of quick response (QR) code, or some other type of scannable data matrix or image matrix code. In this implementation, the scannable code can be displayed on a display screen that is viewable and/or scannable, such as by a user. As an example, the scannable code may comprise data indicative of information associated with the liquid transfer, such as amount of liquid transferred, type of liquid, time of and for transfer, date, location, user/operator ID, transfer target (e.g., aircraft), storage vessel (e.g., tanker truck or stationary tank), flow rate, errors, environmental conditions, and other information that is used for liquid transfer management.
In one implementation, the flow meter may be able to store and provide historical liquid transfer data, such as for transfer operations that have already taken place. For example, such data may comprise shift data (e.g., transfer during a specified time period), various types of fuel transfer, historical error data, and transfer operational data. In this implementation, selected historical liquid transfer data may be converted into a scannable code, and displayed on the display screen.
In one implementation, the data comprised in the scannable code may be encrypted. As an example, an algorithm, such as the Encrypted key—Encrypted QR (EK-EQR) algorithm, may be used. In this example, a user/operator may use an appropriate encryption key to access the data in the code.
In one implementation, a user/operator may use a portable device (e.g., handheld smart device with a scanner) to scan the displayed code. As an example, the portable device may comprise a code scanner or image capture component that scan or capture the code, and store it locally on the device. As one example, the stored code indicative of the fueling data may take the place of a printable ticket. In this implementation, for example, the ability to scan or capture the code displayed on the display screen may be performed without a wireless or wired connection, such as to a network (e.g., PAN, WAN, Internet, or wireless connection), between the meter and the device, or the device and another network. This may provide for additional security, such as from a third party intercepting the data via the network connection, for example.
In one implementation, the stored scannable code, or data associated with the code, can be to a liquid transfer management system, such as a back end system in an office or server, by a variety of means. For example, the code or the data can be sent to the management system by a short message service (SMS) or email, or by some other wireless transfer means. As another example, the portable device may be communicatively coupled (e.g., physically connected via wire) with a component that can download the code or data to the management system. In this way, for example, the data indicative of the liquid transfer operation may be collected in a more secure manner, which mitigates access by unwanted third parties. Further, transfer of the data may not be subjected to inoperable wireless network situations, such as outages or interruptions.
