Patent ID: 8042376

Claim:
A fuel dispenser configured to determine an actual fuel delivery rate at which fuel is being delivered to a vehicle during a fueling process, the fuel dispenser comprising: a fuel delivery path configured to deliver fuel to the vehicle; a fuel meter configured to measure a fuel delivery rate at which fuel is being dispensed through the fuel delivery path to the vehicle; a data set having a plurality of fuel pressure values corresponding to a plurality of actual fuel delivery rate values; a pressure sensor configured to measure a fuel pressure of the fuel in the fuel delivery path; and a controller configured to determine the actual fuel delivery rate at which fuel is being delivered to the vehicle based on the measured fuel pressure from the pressure sensor, wherein the fuel meter determines the measured fuel delivery rate at a given time, the pressure sensor determines the measured fuel pressure at the given time, the controller compares the measured fuel pressure to the plurality of fuel pressure values in the data set and determines which actual fuel delivery rate value from the data set corresponds to the measured fuel pressure and compares the measured fuel delivery rate from the fuel meter to the actual fuel delivery rate value from the data set to determine if the fuel meter is accurately measuring the actual fuel delivery rate at which fuel is being delivered to the vehicle.
