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.
