Orifice flow meters are high-range differential pressure flow devices consisting of a standard orifice plate paired with a multi-parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter, and pressure transmitter). They are capable of measuring gases and steam and are widely used in process control and measurement in the oil, chemical, metallurgical, power, heating, and water supply industries. Orifice flow meters, also known as differential pressure flow meters, are composed of a primary measuring element (throttle piece) and a secondary device (differential pressure transmitter and flow indicator), and are extensively applied in the measurement of flow rates for gases, steam, and liquids. They are characterized by simple structure, easy maintenance, stable performance, and reliable operation.
