Measurement Principle Principles of heat transfer are utilized by thermal mass flow sensors to determine the flow velocity of a fluid. Heat is carried from the sensor to the medium when the fluid ...

This temperature differential is directly proportional to the mass flow measurement. All thermal mass flowmeters work by measuring the cooling effect of a moving gas along a cylinder. The cooling ...

If the mass airflow sensor does not glow red within a couple of minutes of the engine being shut off check to see if the relays are applying voltage to the mass air flow sensor.

Flow meter sensors work in different ways, but with the same end goal: Provide the most accurate and repeatable flow measurements for a specific application, whether for process control, general ...
