Quantitative flow meter microcomputer oil filling machine using advanced computer technology, electromechanical integration equipment. It is suitable for vehicles, oil depots, land farms, factories and other operations to add oil with an ignition point of less than 55 to vehicles or other equipment. This series of oil filling machines is a high accuracy, easy operation, convenient maintenance. Working Principle:Pick up the nozzle, press the start key. The mainboard sends a start signal to the power, and the motor drives the pump to run. The fuel enters the filter and pump, then the OGM gear quantitative flow meter pushes the gear to generate a pulse signal and send it to the mainboard. The mainboard calculates the received pulse signal, measures the fuel quantity and amount, and displays the fuel quantity and amount. The fuel passes through the flow meter and delivery pipe, and output from the nozzle. After refueling, press the STOP key, the mainboard sends a stop signal to the motor drive board, turn off the motor, put the nozzle back to the bracket.
