Abstract:
A system and method of detecting fuel theft at a fuel dispenser. The system has a fluid flow meter, a pulser operatively coupled to said fluid flow meter, and a control system in electrical communication with the pulser. The control system is configured to calculate a flow rate of fuel being dispensed from a gasoline dispenser during a single dispensing transaction. The flow rate is sampled at predetermined time intervals during the single dispensing transaction. The system then compares the sampled flow rates to a predetermined flow rate pattern indicative of potential fraud. A shutoff signal is then provided to the dispenser to stop fuel flow through the dispenser if the sampled flow rates are substantially similar to the predetermined pattern.
Abstract:
A fuel dispenser including a fuel delivery path configured to deliver fuel to a vehicle, a display configured to display the total dispensed fuel volume, and a fuel meter configured to measure a fuel delivery rate. A data set having a plurality of fuel volume compensation values corresponding to a plurality of fuel delivery rate values, and a microprocessor configured to calculate a volume of fuel dispensed and retrieve a fuel volume compensation value. The fuel meter measures the fuel delivery rate at the time of the event, the microprocessor determines which fuel delivery rate value corresponds to the fuel delivery rate, retrieves the corresponding fuel volume compensation value, and adds the retrieved fuel volume compensation value to the calculated volume of fuel dispensed to obtain the total dispensed fuel volume.

Abstract:
A method of determining whether a measured fuel delivery rate determined by a fuel meter of a fuel dispenser corresponds to an actual fuel delivery rate at which fuel is being dispensed to a vehicle through a fuel flow path. The method includes measuring a fuel delivery rate at a given time during a fueling operation, measuring a fuel pressure of the fuel within the fuel flow path at the given time, comparing the measured fuel pressure to a plurality of fuel pressure values from a data set including a plurality of actual fuel delivery rate values that correspond to the plurality of fuel pressure values, retrieving one of the plurality of actual fuel delivery rate values from the data set that corresponds to the measured fuel pressure value; and comparing the measured fuel delivery rate from the fuel meter to the one actual fuel delivery rate value to determine if the measured fuel delivery rate corresponds to the actual fuel delivery rate at which fuel is being dispensed to the vehicle.
Abstract:
A system for assisting handicapped individuals in operating gasoline dispensers which includes a transponder in which data is stored according to the specific gasoline requirements of the individual. A transceiver is located proximate the gasoline dispenser and interrogates the transponder to obtain such stored data, and generates a signal which is a function of the stored data that is transmitted to a computer which receives the signal and generates predetermined control signals for operating the gasoline dispenser. The system may also include a warning signal device activated by the transponder to notify an attendant that the handicapped individual is approaching and this device may include a read-out device which displays predetermined personal information relating to the handicapped individual.
