Thermal Mass Flowmeters

Thermal Mass Flowmeters are suitable for all industrial and test rig applications that demand quick and precise gas measurement. It directly indicate the mass flow or normalized volume flow of gases without any additional pressure and temperature compensation. The flowmeters 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

principle

Thermal sensor consists of two sensing elements - a velocity sensor and a temperature sensor that automatically corrects for changes in gas

temperature(figure1). The transducer electronics heats the velocity sensor to a constant temperature differential above the gas temperature and measures the cooling effect of the gas flow. The electrical power required to maintain a constant temperature differential is directly proportional to the gas mass flow rate.
