FMD-PH Orifice Plate Differential Pressure Flowmeter

Differential Pressure Flow Meter is also called DP flow meter. Differential pressure flow meters use the principle of differential pressure to measure the flow of liquid, gas and steam. It can measure the flow of gas, steam, liquid and natural gas. It is widely used in petroleum, chemical industry, metallurgy, electric power, heating, water supply and other fields. process control and measurement.

The differential pressure flow meter is measured by the working principle that there is a certain relationship between the pressure difference and the flow rate when the medium fluid flows through the throttling device. Differential pressure (DP) flow meters are the most widely used form of flow measurement products today. Differential pressure flow meters have their own characteristics in different fields of use.

FMD-PH orifice plate flowmeter: standard orifice plate can be used to measure the flow of liquid, gas and steam in the pipeline. It is the most widely used flowmeter in fluid measurement, and its disadvantage is the large pressure loss.
