The integrated radio interface for data transmission is pre-configured at the factory to either wireless M-Bus or LoRaWAN^®, depending on the customer’s requirements. This ensures the highest possible flexibility. The B.One Device Manager Basic App allows utilities to effortlessly switch wireless technology, depending on their infrastructure requirements.

The parallel wireless technology is a particular highlight, and enables the IUWS B.One to send measurement data via wireless M-Bus and LoRaWAN^® simultaneously. Regardless of the wireless technology used, this feature guarantees future-proof, seamless integration into existing and new data acquisition systems.

The IUWS B.One ultrasonic water meter can be installed in any installation position: Riser pipe, downpipe or even overhead installation are possible.

All materials used to produce IUWS B.One for the drinking water sector comply with the latest standards, guidelines, the strict requirements of Germany’s regulation for drinking water, and the assessment principles of Germany’s Federal Environment Agency (UBA).
