Thermal mass flowmeter
A flowmeter that measures gas mass flow from the way moving gas carries heat away.
IN ONE SENTENCE
A heated sensor and temperature measurement reveal how much gas is passing.
In normal English
It can measure mass flow directly without separate pressure and temperature compensation in many gas applications.
Why would I use it?
Use it for compressed air, gases and low-flow applications suited to the calibration.
THINK OF IT LIKE…
Measuring flow by seeing how quickly the gas cools a tiny heater.
