Steam Flowmeter

Steam is arguably the most difficult fluid to measure. Other than having to deal with its high temperatures and pressures, it also tends to come in two phases (water and steam) which most flowmeters can’t handle.

The ideal steam flowmeter is a vortex type flowmeter. It uses a highly reactive piezoelectric sensor which measures the frequency of vortices. There are no moving parts, making it highly durable. Our flowmeter is able to take high temperatures of up to 350ºC, making it suitable for measurement of both saturated and superheated steam. In addition, accuracies of up to ±1.5% can be achieved.

TekFlow Vortex Flowmeter

Steam Flowmeter


    Once installed, the flowmeters are virtually zero maintenance and fuss free as no calibration is needed.

    TekFlow’s steam flowmeter is able to measure:
    – Volumetric Flow
    – Temperature
    – Mass Flow
    – Pressure 

    Our flowmeters are calibrated against a gas flow primary standard and traceable to USA National Institute of Standards and Technology (NIST).

    The flowmeter can be integrated into other systems such as a recorder to analyse data and help the user optimise steam flow.
