Which Flow Meter Measures Mass Flow Rate Without Being Affected by Temperature or Pressure Changes?
A thermal mass flow meter is the ideal solution. A flow meter that accurately measures mass flow rate without being influenced by temperature or pressure changes. Unlike traditional volumetric flow meters, thermal mass flow meters directly measure the mass of gases, providing precise results under varying process conditions.
First to understand the difference between mass flow and volume flow?
You can watch the video below or read the following short blog: What is the difference between mass flow and volume flow?
Volumetric measuring devices, like variable area meters or turbine flow meters, are unable to distinguish temperature or pressure changes.
Mass flow measurement would require additional sensors for these parameters and a flow computer to compensate for the variations in these process conditions. Thermal mass flow meters are virtually insensitive to variations in temperature or pressure.
At Mass Flow ONLINE, we offer two high-quality product series that excel in this area:
MASS-VIEW®: Digital Mass Flow Meters with OLED Display
The MASS-VIEW series is a digital alternative to conventional VA meters. It uses thermal mass flow technology to measure gas flow independently of pressure and temperature. Thanks to the integrated OLED display, users can easily monitor flow rates, totalized values, gas type, and units. Ideal for lab and OEM applications.
- Direct thermal mass flow measurement
- Different models with flow ranges up to 200 mln/min and up to 500 ln/min
- High accuracy
- 10 pre-installed gases (Air, N2, O2, CO2, CO, N2O, Ar, CH4, C3H8 and C4H10)
- Bright, graphical OLED display
