Thermal Mass Flowmeters

A common challenge for companies is to meet the demands of industrial and test-rig applications where quick, precise gas measurement is critical. Measurement of biogas and activation air is becoming increasingly more common, but difficult to achieve in low flow and low-pressure applications. Many customers prefer their measurements displayed in mass units which adds to the challenge. The flowmeters are highly accurate with short response times and a wide flow range with little or no loss of accuracy. Thermal mass flow meters provide a mass flow output without pressure or temperature compensation and use the hot film anemometer measuring principle which can measure all technical gases and gas mixtures directly, including compressed air and biogas.
