Nozzle snap flow compensation
First Claim
1. A fuel dispenser configured to compensate a total dispensed fuel volume for an event that occurs during a fueling process, the fuel dispenser comprising:
- a fuel delivery path configured to deliver fuel to a vehicle;
a display configured to display the total dispensed fuel volume;
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 volume compensation values corresponding to a plurality of fuel delivery rate values; and
a microprocessor configured to calculate a volume of fuel dispensed to the vehicle based on the fuel delivery rate and retrieve a fuel volume compensation value from the data set,wherein 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 volume of fuel dispensed as calculated by the microprocessor to obtain the total dispensed fuel volume.

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.

6. A method of compensating a volume of fuel measured by a fuel meter to obtain a total dispensed fuel volume for a fuel dispenser including a fuel flow path for dispensing fuel, comprising:
-
detecting an event that occurs during a fueling operation, the event being detected by a sensor; measuring a fuel delivery rate of the fuel within the fuel flow path at the time of the event; retrieving a fuel volume compensation value from a data set including a plurality of fuel volume compensation values that correspond to a plurality of fuel delivery rate values; and adding the retrieved fuel volume compensation value to the volume of fuel measured by the fuel meter to obtain a total dispensed fuel volume, wherein the retrieved fuel volume compensation value is selected by comparing the measured fuel delivery rate to the plurality of fuel delivery rate values in the data set. - View Dependent Claims (7, 8, 9, 10)
