Gateway V4 + Pegelsonde

Gateway V4 + level probe

The functionality of the Wireless M-Bus Gateway V4 extends this bundle with a high-precision level probe in a compact housing. The measuring probe has a 15 m supply cable and covers a corresponding measuring range.

The measured values are reliably transmitted to the internet via LoRaWAN or mobile radio. An integrated mathematical model in the microcontroller automatically compensates for temperature dependencies and non-linearities - for maximum measurement accuracy.

This bundle is particularly suitable for monitoring levels and gauges, for example in tanks or at groundwater measuring points.
