Compact inline flow sensor for air and nitrogen


No inlet section necessary – integrated flow straightener – optional pressure sensor
The newly developed VA 525 combines modern digital interfaces for connection to an energy monitoring system with a small, compact design. The VA 525 is always used when many machines (compressed air consumers) are to be integrated into an energy monitoring network.
