Patent ID: 7954386

Claim:
A fuel dispenser for dispensing fuel from at least one storage tank to a vehicle, the dispenser comprising: a control system; a fuel flow path configured to receive fuel from the at least one fuel storage tank for dispensing to the vehicle; a meter operatively coupled inline to the fuel flow path and through which fuel passes, wherein the meter is operatively connected to the control system and adapted to transmit a meter signal to the control system in relation to the amount of fuel passing through the meter; and a first pressure sensor operatively coupled to the fuel flow path and configured to sense pressure in the fuel flow path, wherein the first pressure sensor is operatively connected to the control system and adapted to transmit a first signal representative of the pressure sensed by the first pressure sensor, wherein the control system is adapted to: calculate a volume or flow rate of the fuel delivered to the vehicle based on the meter signal; determine if a non-steady state condition exists in the fuel flow path during fueling based at least in part on data corresponding to the first signal; and compensate the calculated volume or flow rate of the fuel in response to the determination of the non-steady state condition.
