Patent ID: 7681460

Claim:
A fuel dispenser for dispensing fuel from fuel storage tanks into a vehicle, comprising: a control system; a fuel flow path to receive fuel from the fuel storage tanks for dispensing to the vehicle; a meter coupled inline to the fuel flow path and through which fuel passes and adapted to generate a meter signal in relation to the amount of fuel passing through the meter to the control system; and a pressure sensor positioned in the fuel flow path that senses pressure in the fuel flow path and communicates a pressure signal associated with the pressure sensed to the control system; the control system adapted to: receive the meter signal from the meter; calculate a volume or flow rate of the fuel delivered to the vehicle based on the meter signal; detect if a non-steady state condition exists in the fuel flow path based on the pressure signal received from the pressure sensor; and compensate the calculated volume or flow rate of the fuel in response to detection of the non-steady state condition, wherein the non-steady state condition is due to a nozzle snap.
