Fuel dispenser calibration
First Claim

1. A self-calibrating fuel dispenser comprising:
- a fuel controller comprising;
one or more pumps configured to deliver fuel from one or more fuel reservoirs to a fuel delivery line; and
one or more meters configured to measure an amount of fuel delivered to the fuel delivery line;
a fuel calibration reservoir separate from the one or more fuel reservoirs and fluidly coupled to the fuel delivery line and at least one of the one or more fuel reservoirs through at least one of the one or more meters, the fuel calibration reservoir sized to contain only a fraction of a fuel volume containable in one of the one or more fuel reservoirs, at least a portion of the fuel calibration reservoir in or adjacent a housing of the self-calibrating fuel dispenser; and
a dispenser manager configured to control fuel delivery by the fuel controller, wherein the dispenser manager is further configured to determine whether the fuel delivery measurement should be calibrated based at least in part on a deviation between a measured amount of fuel contained within the calibration reservoir and the amount of fuel delivered to the fuel delivery line measured by the one or more meters.

Abstract
Systems and processes may provide calibration of a fuel dispenser. In particular implementations, fuel dispenser systems and processes may include the ability to determine whether a fuel delivery measurement of a fuel dispenser should be calibrated and adjust the fuel dispenser in response to the calibration.

14. A method performed by a fuel dispenser comprising at least one processor, the method comprising:
-
delivering an amount of fuel to a calibration reservoir of the fuel dispenser through a fuel delivery line fluidly coupled to one or more fuel reservoirs, the calibration reservoir in or adjacent the fuel dispenser and sized to contain only a fraction of a fuel volume containable in one of the one or more fuel reservoirs; measuring the amount of fuel delivered through the fuel delivery line to the calibration reservoir using one or more meters in fluid communication with the fuel delivery line; measuring an amount of fuel contained in the calibration reservoir subsequent to the delivery of the fuel to the calibration reservoir; determining, by the processor, whether a fuel delivery measurement of the fuel dispenser should be calibrated based at least in part on a deviation between the amount of fuel delivered to the calibration reservoir by the fuel dispenser measured by the one or more meters and the measured amount of fuel contained in the calibration reservoir; and adjusting, by the processor, the fuel dispenser in response to the calibration. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A self-calibrating fueling facility comprising:
-
one or more fuel reservoirs; one or more calibration reservoirs, each comprising a tank and scale configured to measure an amount of fuel contained in the calibration reservoir, the tank sized to only contain a fraction of a fuel volume containable in one of the one or more fuel reservoirs; one or more fuel dispensers comprising; one or more pumps configured to deliver fuel from one or more of the fuel reservoirs to a fuel delivery line in fluid communication with the one or more calibration reservoirs; one or more meters configured to measure an amount of fuel delivered through the fuel delivery line to the one or more calibration reservoirs; a dispenser manager configured to control fuel delivery by the one or more pumps; and a housing configured to enclose at least a portion of the one or more pumps, one or more meters, the dispenser manager, and at least a portion of the tank; and a facility controller configured to determine whether a fuel delivery measurement should be calibrated based at least in part on a deviation between the amount of fuel delivered to the one or more calibration reservoirs measured by the one or more meters and the measured amount of fuel contained in the one or more calibration reservoirs, and send a command to the one or more fuel dispensers in response to the calibration. - View Dependent Claims (23, 24, 25, 26, 27, 28)
