Chapter III Electric control system of fuel dispenser Article I Main functions of electric control system for fuel dispenser Fuel dispenser is operated under electric control, realizing refueling process. Its main function brief as followed: calculation of volume and sales: measuring CPU collect flow data from pulse sensor, and count volume and sales according to certain calculating method fuel dispenser . Finally these data display on screen. Pulse sensor inspection: lock fuel dispenser as sensor occur trouble. Starting motor, stop control, switch on and off solenoid valve. Display function: show various filling information on screen Dialogue function: filing staff realize general operation thro fuel dispenser ugh keyboard, display screen and nozzle switch. Network communication function: all fuel dispenses in network are managed and controlled by centre-control computer. Article II Electric control system configuration of fuel dispenser 1. General structure Diagram 3-1 illustrated single nozzle fuel dispenser, mechanical section showed in broken line ---- also called hydraulic components, yet real line is showing the electric section (system) of fuel dispenser, including measuring main board, keyboard, display screen, control circuit of motor and solenoid valve, motor, solenoid valve, pulse sensor, nozzle switch, power supply board, junction box of AC current and communication box. Diagram 3-1: Structural sketch map of fuel dispenser mounted single nozzle There is little difference between double and single fuel dispenser in electric control system, the former having two sets of display screen, keyboard, a control of fuel dispenser
