Orifice flowmeter, also known as differential pressure flowmeter, is composed of a primary detection part (throttling part) and a secondary device (differential pressure transmitter and flow display instrument). A high range ratio differential pressure flow device composed of a standard orifice plate and a multi-parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter and pressure transmitter), which can measure gas, steam, liquid and natural gas, It is widely used in process control and measurement in petroleum, chemical industry, metallurgy, electric power, heat supply, water supply and other fields.
