The newly developed VA 521 combines modern digital interfaces for connection to an energy monitoring system 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.
The high-contrast, integrated display also displays the current values rotated by 180° if desired (very useful for overhead installation). 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
- Temperature measurement
