摘要:
A fuel dispenser containing electronic/electrical components controlled by a computer is disclosed. The computer and all electronic components, including a touch screen display, are mounted in a module or rack provided with a pair of slides. A recess in the fuel dispenser receives the module on mating slides. At least one connector or plug on the back of the electronics module engages a mating plug mounted in the recess so that when a replacement electronics module is installed, connections to all electronic components is automatically made. As one feature of the invention, configuration data for the fuel dispenser is stored in a flash memory either permanently mounted to the computer or in removable relation therewith. After replacing an electronics module, the configuration data may be uploaded to the permanently mounted flash memory or the flash memory may be removed from the defective module and installed in the operating module. This eliminates the need to manually re-enter configuration data after repair of the fuel dispenser.

Disclosed are methods, systems, and computer program products to prevent a delivery vehicle from making an unauthorized delivery of liquid product to a liquid product storage tank at a retail store facility. A retail system and/or a centralized inventory management system can monitor one or more tanks at the retail facility for liquid product delivery from the carrier. The retail system and/or the centralized inventory management system can automatically interrupt delivery of liquid product when the delivery vehicle begins to delivery the liquid product to an unauthorized tank.

Disclosed is a virtual real-time liquid product book to physical reconciliation process within a dynamic environment. The method can include receiving a request to perform a liquid product book to physical reconciliation process for one or more storage tanks at a retail facility. Once received, the status of one or more liquid product dispensers corresponding to the one or more storage tanks can be identified. A plurality of measurements can be made while the one or more liquid product dispensers are in an active state and dispensing the liquid product. With the data indicative of the plurality of measurements, the method can automatically perform the liquid product book to physical reconciliation process.

Disclosed are methods, systems, and computer program products for balancing net inventory using a dynamic expansion coefficient of liquid product relative to the temperature changes with density. The method can include receiving an API gravity report that includes a measurement of a specific gravity and a temperature of the product reported at a rack. Utilizing the API gravity report, the method can include maintaining correct densities of the liquid product by utilizing a plurality of expansion coefficients to dynamically convert a gross volume measurement to a net volume measurement for transactions of liquid product in a tank and at a dispenser in order to maintain a net perpetual book balance.

A fuel dispenser with a flow meter prevents fraud in the form of flow meter replacement by storing a unique identifier in the memory associated with the flow meter. The unique identifier is stored in the memory of the fuel dispenser as well. Prior to each fueling transaction, the unique identifiers in the respective memories are compared. In the event that a match is not found, an alarm may be generated. A calibration factor may likewise be stored in both memories and compared concurrently with the unique identifiers. In an alternate embodiment, each element of the flow meter has a unique identifier which is compared prior to a fueling transaction.

摘要:
An electronic refueling transaction receipt is generated at a fuel dispenser position. The electronic receipt can be wirelessly communicated to a user device associated with the refueling customer. The electronic receipt can also be communicated to a remote location such as a network address or e-mail account. For this purpose, the user device communicates to the fuel dispenser a destination address specifying the location where the dispenser should transmit the virtual receipt, such as an e-mail address. The user device can direct the execution of remote management functions involving the fuel dispenser. The communication exchange to facilitate the management operations includes the use of a wireless link between the dispenser and user device. The remote management tasks include diagnostics and calibration.
摘要:
A method and apparatus for storing test data in a fuel dispenser. The test data is generated for the fuel dispenser. The test data is then stored to a nonvolatile memory within the fuel dispenser.
摘要:
The present invention relates to a system and a method for compensating for predicted meter drift is a positive displacement meter comprising a pulser connected to the meter for generating a pulse stream indicative of a current volume delivered through the meter; and a pulse processor in electronic communication with the pulse generator. The pulse processor adds or subtracts pulses indicative of the inverse of the predicted meter drift to or from the pulse stream to create a corrected pulse stream. The amount of inverse applied is determined by the value of the current cumulative volume passed by the meter.
摘要:
The invention relates to a calibration apparatus for control of propellant pumps, especially in the traffic sector, which apparatus is placed on a vehicle, especially a trailer. The apparatus (1) has at least one standard (10) for measuring a determined amount of propellant, and the standard is placed in a cardan suspension (49-52) which is elastically yielding (48) and may be locked during operation and during transport by means of supporting rods (53-59). A standard (10) is divided into a lower measuring compartment (11) and an upper foam top (14) which is connected tot he measuring compartment (11) through a neck (12) with a measuring glass (13) and reading lines (22). The foam top (14) is ventilated (35-37) to reception tank (5) placed at the bottom of the apparatus (1), and the standard (10) may be connected via a remote controlled discharge valve (20) to the reception tank (5) from which propellant may be pumped up into a buffer tank (64) at the top of the apparatus (1). From here the propellant may be returned to the storage tank of the tank station through a hose (72) either by the aid of gravity or by means of a pump. An electric generator (78) which may be driven by a belt drive (79-84) connected to one of the road wheels (2), may charge an accumulator (87), and a pressure container (88, 89) with a non-flammable pressurized gaz, e.g. carbondioxide, is provided for remote control of the discharge valve (20). A control device for time control of the functions of the apparatus is further provided.
