- Measurement of mass flow direct output of standard volume flow
- Highly accurate at small as well as higher flow rates
- Pressure and temperature compensated by the thermal mass flow principle
- Quick and easy installation via a ½" ball valve
- No moving parts, thus low maintenance
- Vanishingly low pressure drop due to vanishingly low blockage of the diameter
- Can be used for compressed air and non-corrosive gases such as nitrogen, oxygen, argon, helium, etc.
