Flow sensor with integrated flow straightener / no inlet sections necessaryInquire now
The newly developed VA 521 combines modern digital interfaces for connection to an energy monitoring system with a small, compact design. The high-contrast, integrated display also displays the current values rotated by 180° if desired (very useful for overhead installation).
The VA 521 is always used when many machines (compressed air consumers) are to be integrated into an energy monitoring network.
Depending on the configuration, two of the following values can be displayed:
Current consumption in m³/h, l / min, ...
Total consumption (meter reading) in m³, l, kg
|The advantages at a glance:|
Screw thread for easy installation in existing piping through integrated measuring block
Compact, small design - for use in machines, behind maintenance unit at the end user
All interfaces are programmable via the display
Modbus RTU output
4...20mA analog output for actual flow
Pulse output total flow (counter reading), galvanically isolated. Optionally M-Bus, Ethernet-Interface, or PoE
