In this tutorial we will discus the basic working principle of an orifice plate flow meter as the orifice creates a pressure drop across the orifice plate which varies with the flow rate, resulting in a differential pressure between the outlet and inlet segments. This pressure drop is measured and is used to calculate the flow rate of the fluid or gas.
