Thermal Mass Flowmeter The thermal mass flow meter is a precision device designed to directly measure the mass flow rate of gases using heat transfer principles. By detecting the heat carried away from a heated sensor as gas flows past, it delivers accurate, real-time measurements with no moving parts and minimal maintenance. Ideal for industrial applications, this meter ensures reliable performance and high sensitivity, even at low flow rates.
