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.

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.
Eccentric type orifice is used for both gas-liquid mixture type flow application.
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.
measures the rate of fluid flow
The orifice meter is used with the orifice flow rate meter and measures things like the flow rate of natural gas. It can measure other things and companies use it for different things also. Some companies give lessons or classes in using the orifice meter.
