Air Flowmeter

Tekflow’s Air Flowmeter is based on thermal mass principle. It can measure the mass flow of single or mixed gases in both directions. Because it measures mass directly, there is no need to measure temperature or pressure for compensation. The accuracy can be up to ±0.5% full scale with USA NIST and international traceability.

TekFlow Thermal Mass Flowmeter

Air Flowmeter

    Description

    The main benefits of thermal mass flowmeters are its high turndown ratio and low pressure losses. Our air flowmeter is suitable for pipe sizes from  1/2” – 240” for the insertion type, and 1/2”–12″ for the in-line type. The in-line type has the benefit of easy installation and more accurate readings. For the insertion type, it is possible to measure gas flows in very large pipelines or in rectangular ducts at relatively low costs. 

    Our air flowmeters are typically used in many industries for measuring flow rates of gases, such as:

    • Compressed air
    • Carbon Dioxide
    • Nitrogen
    • Oxygen

    However, it is not recommended for explosive gases as its measuring principle relies on a heating element.
