ABSTRACT:
A vapor recovery system used with a fuel dispenser and having capabilities incorporated therein for controlling the rate at which vapor is recovered. The vapor recovery system includes a fuel delivery line connected to a fuel nozzle, a vapor return line connected to the fuel nozzle, a vapor pump in the vapor return line, and a processor connected to the vapor pump. The processor controls the speed of the vapor pump and the vapor recovery rate by generating and directing vapor pump control signals to the vapor pump. The vapor pump control signals are generated by solving a vapor control function stored in a memory operatively connected to the processor. The vapor control function includes a dependent sub-function dependent on independent variables that affect the rate of vapor volume generated during a fueling operation. To solve the control function, the processor accesses solutions to the dependent sub-function via a look-up table containing pre-computed dependent values.
