CS Instruments VA 500 | Thermal Mass Flow Sensor for Compressed Air and Gases | 1/2in to 40in, 50 bar, IP 65
The VA 500 measures mass flow and outputs standard volume flow for compressed air and non-corrosive gases such as nitrogen, oxygen, argon and helium. It fits pipes from 1/2in up to 40in, larger on request, and goes in through a 1/2in ball valve under pressure. One device can monitor consumption and evaluate leakage flows, and its design also suits mobile measurement.
