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
