VA 550 - Thermal mass flow sensor for flow measurement
Flow meters for compressed air and other technical gases
Reduce your energy costs and increase your sustainability with the VA 550. 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 at a glance:
- All wetted parts are made of stainless steel, especially for applications with high demands on cleanliness and surface quality
- Rough industrial applications can be realized due to robust aluminum housing
- Recommended for flammable gases such as natural gas, hydrogen, biogas, etc. due to ATEX or DVGW approval
- Measurement of mass flow rate, direct output of standard volume flow rate
- Highly accurate at small as well as large flows
- Pressure and temperature compensated by the thermal mass flow principle
- Quick and easy installation via a standard ½'' ball valve
- No moving parts, therefore low maintenance
- Vanishingly low pressure loss due to vanishingly low blockage of the diameter
