ABSTRACT:
A system for computing and displaying quantity and cost of a liquid flowing through a pipe, as gasoline delivered to a consumer. A detector responsive to the passing of a predetermined quantity of the liquid provides a pulse function to money and quantity set circuits. The money and quantity set circuits simultaneously provide signals representative of the units (i.e., gallons) and cost (i.e., dollars) each time a pulse function is received. The signals are accumulated in a memory and the totals are added to subsequently received signals to update the memory each time the predetermined quantity has passed. A nonvolatile totals memory provides a running total of cost and quantity and a sequentially operated display provides a visual display of cost, quantity and totals.
