METHOD AND SYSTEM FOR DISPENSING E AMOUNT OF FLUID WITH AUTOMATIC SET RESET A method and an automatic control system for dispensing a desired precise amount of a fluid from a reservoir by automatic control of a pump. The fluid is discharged through an operator actuable dispensing mechanism which is operated by a user. More particularly, but not exclusively, the system is associated with a gas pump apparatus. The system detects a slow-down or a stoppage in the discharge of the fluid by sensing a signal at the output of a counter which is provided with the gas pump. These signals actuate the controls circuit to sense parameters of the counter whereby to initiate a slow rate of discharge of the fluid from the pump during a predetermined time period before a preset integral amount and after the slow-down or after the reactivation of the actuable dispensing mechanism if a stoppage of the mechanism was detected. After the integral amount is reached, the pump is shut off during a shut off period of time after which shut off period of time, the pump is re-activatable by actuation of the actuable dispensing mechanism. Accordingly, this system greatly facilitates the dispensing of a precise volumeric or cost amount of a fluid, such as gasoline.
