Abstract
Abstract A system for dispensing a quantity of gasoline having a selling price equal to a predetermined denomination of paper currency, such as a one dollar bill. A computing pump is provided including a driving motor, a flow meter which measures the volume of gasoline delivered by the pump, and a selling price computer operated by the flowmeter. A bill reader is provided which receives and inspects the bill to determine its validity and denomination and provides an output signal when the bill has been determined to be valid and of the correct denomination. The motor is started to initiate the pumping operation in response to the output signal from the bill reader and the motor is stopped to terminate the pumping operation by the selling price computer when the selling price of the gasoline dispensed equals the denomination of the bill. A coin-actuated device is provided into which a coin, such as a quarter, must be deposited before the dispensing nozzle can be removed from the holder. Upon properly returning the nozzle to the holder, the coin is returned. Operation of the system is inhibited until the nozzle has been properly positioned and locked into the fill pipe.
