Item # 0695 5250 A4, VA 521 G 1-1/4 Inch (in) Thread Size Compact Inline Flowmeter

Web Price QUOTE


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.

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