Abstract
Abstract A system for monitoring and controlling the operation of a plurality of fluid dispensers, such as gasoline pumps or the like in a self-service gasoline station is disclosed. The system includes an operating console that may be located in a station building and has electronic displays, dispenser selecting push buttons and a keyboard including numeric and functional switches, all of which an operator can use to control the operation of the system. A mode select switch permits operation of the system in various modes, selected ones of which permit an operator to obtain various period totals of both volume and cost, to control normal postpay or prepay dispensing transactions, check inventory as well as set or reset the cost per volumetric unit, among other operations. The system can include electronic displays at the gasoline pump and permit price setting of the fluid product from the console.
