ABSTRACT:
A refuel control system is disclosed which may be utilized in a gasoline or other fluid refuelling operation. This system effectively prevents differences in refuelled volume and accurately determines the amount of fluid dispensed. Differences in refuelling operations for a particular dispenser may be due to pressure variations inside a refuel pipe during the initial stages of refuelling and before gasoline is actually flowing through a discharge nozzle. This system involves the use of sub-CPU which reads initialization time data from a host CPU. A motor is then activated to pump fluid to the nozzle after which pulses are generated in response to the flow of gasoline. The sub-CPU receives these pulses and then inhibits counting of these pulses until the time period for that particular pumping operation corresponds to the initialization data. After this period, pulses are then monitored in order to correctly determine the actual amount of gasoline dispensed. The initialization time data may be varied such that this sytem may be made specific to a particular dispenser.
