CS Instruments VA 521 | Compact Inline Flow Meter for Air and Gases | 1/2in to 2in, 40 bar, 80 °C
The VA 521 is a compact inline flow meter from 1/2in to 2in that tracks the consumption of each machine and reveals leakage flows. It measures mass flow of compressed air and non-corrosive gases such as nitrogen, oxygen, argon and helium, and needs no inlet or outlet runs thanks to its integrated flow straightener. The sensor can be removed while the measuring section stays in the line.
