WebDec 14, 2024 · Facts About Orifice Flow Meters. by Editorial Staff. The orifice plate is for flow measurement : an inexpensive yet effective primary sensing element. The concept is disarmingly simple. Place a restriction in a pipe, then measure the resulting pressure drop (ΔP) across that restriction to infer flow rate. WebMar 22, 2024 · The pressure at the entrance to the orifice is thus 50 torr, and the pressure after the orifice is 0.01 torr, so the gas velocity through the orifice is about 320 m/sec. The flow area is the orifice flow area times the orifice coefficient of about 0.6. Velocity times area times density gives you mass flow rate. WebThe pressure drop or flow rate through a valve or orifice plate is typically calculated using the a flow coefficient, Cv or orifice diameter.
