The intelligent alternative for VA meters, rotameters or purgemeters:
thermal Mass Flow Meters for gases with flow display

The MASS-VIEW^® series operate on the principle of direct thermal mass flow measurement. A major advantage of using this type of sensor is that the instruments measure direct mass flow, without the need of temperature and pressure correction. The MASS-VIEW^® has compared to conventional meters high accuracy and rangeability (up to 1:100). Available full scale ranges are 0.2 up to 200 l_n/min (or SLM) relative Air (SLM equals l_n/min at 0°C and 1 atm) For your convenience, we also have our flow ranges in other flow units.

MV-102 meter pre-installed gases ranges Air, N2, O2 and CO2 0.2 .. 2 Ar 0.5 .. 4 CH4 and C3H8 0.1 .. 1 maximum full scale ranges expressed in ln/min (SLM)

MV-104 meter pre-installed gases ranges Air, N2, O2 and CO2 2 .. 20 Ar 5 .. 40 CH4 and C3H8 1 .. 10 maximum full scale ranges expressed in ln/min (SLM)

MV-106 meter pre-installed gases ranges Air, N2 , O2 , CO2 20 .. 200 Ar 50 .. 400 CH4 and C3H8 10 .. 100 maximum full scale ranges expressed in ln/min (SLM)

We also offer dedicated meters for Hydrogen (H2) or Helium (He)
(see our models MV-192-H2/He, MV-194-H2/He, MV-196-H2/He).
Available full scale ranges are 1 up to 100 l_n/min (or SLM)  H2/He.
