ABB Thermal Mass Flowmeters

FMT200 and FMT400

Sensy Master FMT200 and FMT400

ABB’s thermal mass flowmeters are suitable for all industrial and test rig applications that demand quick and precise gas measurement. The flowmeters directly indicate the mass flow or normalized volume flow of gases without any additional pressure and temperature compensation. They have an impressively high accuracy, short response time and a very wide flow range with virtually no loss of accuracy even at the lowest flow rates.
