Abstract
A processor is used to control a price display unit for a fluid-dispensing system. The amount of fluid dispensed by the system in measured and information responsive thereto is fed to the processor. The processor calculates the cost of the dispensed fluid and those costs are then displayed. The processor automatically cross-checks the validity of the displayed cost with the amount of fluid dispensed. A plurality of self-checking features insure proper system operation and also preserve signals stored in a memory if there is a power failure.
