for measuring the rate of flow of fluid.
Orifice meter is a flow measuring device used for calculating the pressure drop,flow rate and behaviour of the fluid moving through the pipe.
orifice meter is used for measuring volume flow rate air.
The way a flow sensor works depends on the type of flow sensor. The simplest forms like mechanical flow meters use a pressure sensor to measure volume capacity and rate. Essentially a flow sensor measures the quantity of liquid by measuring force created by it's movement. They can do this either mechanically or electronically.
A device for measuring the flow of a liquid.
Orifice meter measures pressure by forcing fluid through a restriction (orifice plate) in the pipeline, causing a pressure drop. This pressure drop is proportional to the flow rate, which can be used to determine the pressure of the fluid. By measuring this pressure drop, the orifice meter can indirectly measure the pressure of the fluid in the pipeline.

A restriction orifice (RO) is used to limit the flow through the pipe to a set flow by choking the flow at its sonic velocity. A flow orifice (FO) is usually used to determine the flow through the pipe from the pressure drop over the plate. There a normally two pressure taps (one on each side of the plate) and a pressure transmitter which determines the pressure drop over the plate. A formula is then used to convert this pressure drop to a flowrate for the specific fluid passing through the orifice. A FO usually has a temperature element to determine the gas temperature for use is the formula.
An eccentric orifice plate is specifically designed for measuring the flow of liquids containing solids. Its off-center position helps prevent clogging or blockages by allowing debris to pass through more easily compared to a concentric orifice plate.
MAF....Mass Air Flow....and MAP....Manifold Absolute Pressure
Because it relies on the back pressure through a known orifice which its differential pressure across the plate relates to flow.
An orifice in fluid mechanics is a small opening or hole through which fluid flows. It is typically used in devices such as nozzles, Venturi meters, and orifice plates to measure or control the flow rate of a fluid. The size and shape of the orifice affect the flow characteristics of the fluid passing through it.
