The KOF200 series orifice flowmeter is a scale-free flow measuring device that is used with a pneumatic, electric differential pressure transmitter or double bellows differential pressure transmitter. The pressure difference generated by liquid, gas and steam flow of metallurgy, chemical, petroleum and power industry ℃ through the orifice plate transforms the pressure signal into a proportional output signal, with a secondary instrument or regulator, recording the measured flow rate, indicating or adjusting.

Application industry: widely used in metallurgy, chemical industry, petroleum

, electric power industry and other industries.
