For more on marking an answer as the "Best Answer", please visit our FAQ.A petrol pump pumps petrol. A petrol meter meters petrol. An old fashioned analogue petrol meter does not usually involve any calculations, whereas a digital one does. What exactly do you want to know? If you phrase your question carefully you will probably get the answer you want. I am not being difficult, I just don't want to waste my time giving the wrong answer ie. one that you don't want.
Flow sensors usually work by having a vane that rotates more or less in proportion to the rate of flow of the liquid that passes it. The vane is in a flow chamber has a small magnet attached to it that passes a coil or other sensor on the outside of the flow chamber. Every time the magnet passes the sensor it generate an electrical pulse. The pulses are counted electronically and calibration adjustments made to correct the volume reading.
Or according the the Wikipedia article (which I'd have no reason to doubt in this instance.) the flow metering is done by a four stroke piston meter (i.e. the pump itself)
