Orifice flowmeter is a high range ratio differential pressure flow device composed of standard orifice plate and multi parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter and pressure transmitter). It can measure the flow of gas, steam, liquid and natural gas. It is widely used in the process control and measurement of petroleum, chemical, metallurgical, electric power, heating, water supply and other fields. Orifice flowmeter, also known as differential pressure flowmeter, is composed of primary detection parts (throttling parts) and secondary devices (differential pressure transmitter and flow indicator). It is widely used in gas, steam and liquid flow measurement. It has the characteristics of simple structure, convenient maintenance, stable performance and reliable use.
