OVERVIEW
The orifice plate throttling device is tightly combined with a differential pressure transmitter through a three valve group to form an integrated orifice plate flowmeter.
Integrated orifice flowmeter can be widely used in industries such as petroleum, chemical, natural gas, metallurgy, power, and pharmaceuticals for continuous measurement of volume flow or mass flow of various liquids, gases, natural gas, and steam.
FEATURES
- Integrated structure, good completeness
- High measurement accuracy and wide range ratio
- The pressure difference can reach 30mmH2O
