Thermal Mass Flow Meter

Working on the principle of heat transfer, this meter measures the mass flow of gases directly with high accuracy and minimal maintenance.

  • Digital transmitter for low-noise, highly accurate signal output
  • Direct mass flow measurement—no pressure or temperature compensation needed
  • Also provides gas temperature and totalized flow as outputs
  • Handles a wide range of clean or slightly moist gases, including air, nitrogen, natural gas, and process gases

FAQs

1. What is a Thermal Mass Flow Meter?
A Thermal Mass Flow Meter measures the mass flow rate of gases by detecting how much heat is carried away from a heated sensor by the moving gas.
2. How does a Thermal Mass Flow Meter work?
The Thermal Mass Flow Meter uses a small heater and temperature sensors. As gas flows past, it cools the heater, and the meter calculates mass flow from the change in temperature.
3. What are the advantages of a Thermal Mass Flow Meter?
> Direct mass flow measurement without separate pressure or temperature compensation
> Fast response and stable, repeatable output
> No moving parts, so maintenance is minimal
> Can also provide gas temperature and totalized flow as outputs
4. Which gases can a Thermal Mass Flow Meter measure?
A Thermal Mass Flow Meter can measure most clean or slightly moist gases, such as air, nitrogen, natural gas, and many industrial process gases.
5. How accurate is a Thermal Mass Flow Meter?
Depending on the model, a Thermal Mass Flow Meter typically achieves ±0.5 % of reading or better, ensuring precise and reliable gas flow measurement.
