VA 500 - Flow meter for compressed air and gases
Thermal mass flow sensor for compressed air and gases
Recording and reducing energy costs and CO2 emissions while increasing the sustainability of any compressed air system. With our VA500 it is possible to monitor your consumption and analyze your leakage flows with just one measuring device. Due to its design, it is also ideal for mobile measurements.
Advantages of the VA 500 flow meter:
- 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.
