What is the function of a concentric orifice plate?

A concentric orifice plate is primarily designed to measure flow rate in a piping system. It creates a restriction in the flow path, which causes a pressure drop that can be correlated to the flow rate of the fluid passing through it. As the fluid flows through the orifice, the difference in pressure before and after the orifice can be measured. This differential pressure is directly related to the flow rate, allowing for accurate measurement when used in conjunction with flow rate equations.

While temperature, pressure, and signal conversion are important parameters in power engineering, they are not the primary functions of a concentric orifice plate. Instead, other devices and instruments are typically employed for measuring temperature (like thermocouples), monitoring pressure (such as pressure gauges), and converting signals (like transmitters and transducers). In the context of flow measurement, the concentric orifice plate is a specialized tool that effectively quantifies how much liquid or gas passes through a system.
