Abstract
Abstract A system for dispensing of multiple grades of gasoline which utilizes electronic computational and control devices to meter selected grades of gasoline and accurately compute the money price of dispensed gasoline. The system utilizes meters controlling flow of regular and premium grade gasolines in such manner that controlled blending allows dispensing of any of a plurality of separate grades or octane ratings of gasoline, and computational equipment driven in response to such metering outputs accurately compute the gallonage delivered in ratio as well as the proportional unit price for the particular selected grade of gasolines dispensed. This equipment is utilized at a plurality of dispensing bays with all dispenser consoles under further control of a central console, and all quantities of premium gasoline, regular gasoline, selected grades of gasoline, and prices of dispensed gasoline are continually totalized at a central location to provide constant inventory readout for the particular station.
