Thermal Mass Flow meter

How does a Thermal Mass Flow Meter work?

Whenever a fluid of a certain temperature is passed over any substance hotter than the fluid, the heat of the hot substance is taken away because of forced convection by the fluid, and the temperature of that substance drops. This fall in temperature is related to the mass flow of the fluid passing over the substance. If one can measure the amount of heat taken away by the flowing fluid one can calculate the mass flow rate.

Where are Thermal Mass Flow Meters used?

Some of the applications of Thermal Mass Flow Meters include Compressed Air in various industries, Oxygen Generators, and other compressed gases, flow measurement of gases like CNG, PNG, LNG, LPG, Biogas, Nitrogen, etc.

Being a direct mass flow meter, it does not require any pressure and temperature compensation.

Thermal Mass Flow Meter- Theory Of Operation

A Thermal Mass Flow Meter contains two Platinum RTD temperature sensors for this purpose. One sensor measures the fluid temperature as a reference. The second sensor is heated and has a constant temperature differential relative to the first sensor. When the flow of air/gas starts heat is taken away from the warmer sensor. The amount of heat taken away is having a direct relation with the mass velocity of the fluid. That is how it is a direct mass flow meter.

Being a direct mass flow meter, it does not require any pressure and temperature compensation.
