Question can you tell me, how a pump of gas station works?
Answer A gas station pump has three main components:
The first is a pump that actually pumps the gasoline out of the tank. The second is the PD meter, or a positive Displacement Meter that the gasoline flows through. It works a bit like a revolving door in a way that every revolution of the revolving door a fixed very accurate volume of gasoline goes through it. The speed of the pump may vary but the PD meter will always measure an exact quantity of gasoline. The third part is the counter that takes the information from the PD meter and converts it into gallons and dollars and cents. When you have pumped an acceptable number of gallons, or dollars of gas, you stop the pump and pay. If you are filling up the tank of your car, another system works that detects when your tank is full. It works by sending small pulses of gasoline through the line. If there is still air in your tank, the pulses are dissipated in the tank, if your tank is full, the pulse is returned through the hose and detected. When the return pulse is detected it stops the pump. Next time you load gas, if you concentrate, you can feel the pulses of gasoline in the nozzle. They get stronger as the tank fills.
