ABSTRACT:
Method and apparatus suitable for the retail sale of gasoline (as well as for other fluid delivery systems) in terms of standard quantities (e.g., gallons) at a standard temperature, such as 60.degree. F. The apparatus for retail gasoline sale provides a pressure differential for moving the gasoline from a storage tank to a hose, and it includes a metering device preferably having a rotating shaft and a shaft-angle encoder for generating a positive angle continuous, electrical signal as a function of the shaft angle output. The instantaneous temperature of the gasoline in the nozzle is sensed and a thermal value signal generated from it several times per second. A rapid electronic computer computes from the continuous gallonage signal and the thermal value signal, at intervals of several times per second, the gallonage corrected to standard gallons at 60.degree. F. and actuates a display of the computed dispensed gallons in terms of standard gallons at 60.degree. F., and the money price thereof in terms of standard gallons at 60.degree. F. The electronic computer has sufficient capacity to provide calculations for two similar or different gasoline products being simultaneously dispensed through a "twin hose" type of dispenser. Parallel display, front and back, is also a simultaneous attribute for the single hose dispenser as well as the twin hose dispenser.
