HPF series integrated orifice flowmeterDetailed product description：

The HPF integrated orifice flowmeter is 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). It can measure the flow of gas, steam, liquid, and natural gas, and is widely used in process control and measurement in fields such as petroleum, chemical, metallurgical, power, heating, and water supply.

Scope of application
1. Nominal diameter: 15 mm ≤ DN ≤ 1200mm
