Orifice Meter definition

Orifice Meter means an inferential meter that consists of an orifice plate perpendicular to the gas flow in a pipe. When gas flows across the orifice, it creates a pressure differential. Transmitters and transducers measure the pressure differential, static pressure, and other variables to determine the flow rate. The flow rate is proportional to the square root of the differential pressure across the orifice plate.
