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 28, 2024 · As the fluid flows through an orifice, the pressure drops across the pipe. This phenomenon is also used to measure fluid characteristics. Mathematically, the orifice flow equation gives the mass …

WebWhen this Orifice Plate is placed in a line, a differential pressure is developed across the Orifice Plate. This pressure drop is linear and is in direct proportion to the flow-rate of the liquid or gas. Since there is a drop in pressure, just like Turbine Flow meter, hence it is used where a drop in pressure or head loss is permissible.

WebWith orifice flow meters the pressure difference over an orifice in the flow is measured. Measured pressure difference is proportional with flow velocity squared.
