Applicable Industries

The vortex flowmeter is designed based on the Karman vortex principle, which can measure the flow, temperature, pressure and other parameters of the medium fluid of industrial pipelines according to different types, and has the functions of pulse frequency output, 4-20mA analog signal output, RS485 communication, Hart protocol and so on. It is widely used in heating, gas supply,textile, steel, medicine and other industries to measure and control gas, compressed air, steam, nitrogen, heat transfer oil and other media.

Note: Choose Temp And Pressure Compensation For Gas Measurement

Gases are highly susceptible to pressure and temperature, which requires accurate measurements, temperature 25ºC and standard atmospheric pressure.

However, field conditions often can not be satisfied, therefore, it is necessary to involve temperature and pressure compensation.
