2About Thermal Mass Flow Meter
- It is used to calculate the total mass flow rate
of fluid, mainly gases, flowing through closed
conduits. - It is a direct mass flow meter with no moving
parts - Works effectively for large pipelines.
- Doesnt require any pressure and temperature
compensation
3Theory of Operation
- Thermal Mass Flow Meter contains two Platinum RTD
temperature sensors - 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 works.
4Features of Thermal Mass Flow meter
- Simple for installation.
- There are no moving parts.
- Pressure and Temperature compensation is not
required. - Almost unobstructed straight flow path.
- Very negligible pressure loss and pressure
requirement, unlike differential pressure flow
meters. - Straight pipe runs can be reduced by using flow
conditioners or flow straighteners. - Very good repeat accuracy.
5Applications of Thermal Mass Flow Meter
- Compressed air/ Gas Consumption measurement
- Gas measurement at very low-pressure flowing
conditions - Fuel Gas like CNG consumption measurement and
control - Automobile gas engine testing
- Industrial oxygen flow measurement and control
- Furnace and burner control
- Biogas measurement in digester biogas digester
systems
