The working principle of the fuel dispenser

The working principle of the fuel dispenser involves multiple parts such as the oil tank, pump group, metering system, control system and display system.
1. Oil tank: The oil tank is a container for storing liquid fuel, which has corrosion resistance and good sealing performance. A liquid level sensor is installed inside the oil tank to monitor the changes in the amount of oil in the oil tank.
2. Pump group: The pump group is responsible for pumping the fuel in the oil tank to the refueling gun.
3. Metering system: The metering system is used to accurately measure the amount of fuel added, including components such as flow meters, metering controllers and metering sensors.
4. Control system: The control system is responsible for monitoring and controlling the working status of the fuel dispenser. It consists of an electronic control unit (ECU) and related sensors.
5. Display system: The display system is used to show users information such as the amount of fuel added and the amount of money
