Abstract
Automated fluid dispensing apparatus operative under stored program control includes an attended console for controlling an array of dispensing pumps or the like, e.g., a pump island in a self service filling station. An array of data input fields, display and status signalling fields and control keys are disposed on the console. Input signalling from the console may illustratively comprise data from price-per-gallon and transaction limit registers, pump enabling keys, and display controls. Console presentations are for such as pump identity and status, and dispensed fuel value or volume. A microprocessor is connected to the console equipment, and to individual pump controllers, sensors and the like. Fluid flow at each pump is thus readily monitored and controlled by an attendant at the console via the microprocessor.
