Fuel dispenser

摘要

A fuel dispenser is disclosed. The fuel dispenser has a housing which contains two chambers, one contains a computer and the other the hydraulic parts of the dispenser. Fiber optic cables connect a fiber optic switch which detects the cradling of a nozzle to a computer, and other fiber optic cables connected to a pulser signal the flow of fuel in the meter of the dispenser to the computer. The computer controls a liquid crystal display which prompts the customer to actuate keys on a keyboard adjacent to the display. A pivotal boot supported by a horizontal shaft receives the nozzle. This boot pivots to permit better access to the hydraulic area of the housing. The shaft, itself, is rotatable to actuate a switch to indicate, through fiber optic cable, to the computer that the nozzle is stored and to shut down pumping. A fiber optic pulser feeds light signals to the computer for indicating the flow of fuel through the meter. A temperature probe adjacent to the display signals the temperature of the display to the computer so that the computer automatically controls the voltage bias, and thus the contrast, of the liquid crystal display. The computer provides selective screens which enables the parameters of operation of the dispenser to be changed and supplies diagnostic data on screens for repairs.
