No inlet section necessary - integrated flow straightener - sensor unit removable

The newly developed VA 521 combines modern digital interfaces for connection to energy monitoring systems with a small, compact design. The VA 521 is always used when many machines (compressed air consumers) are to be integrated into an energy monitoring network.

Readout values in the display can be rotated by 180º, e.g. for overhead installation

The sensor can be removed from the measuring section and cleaned.
