IUWS B.One
Ultrasonic apartment / domestic water meter for cold water
The IUWS B.One ultrasonic water meter ensures precise consumption data recording in the residential and domestic water sector.
The water meter’s state-of-the-art ultrasonic technology provides
reliable, accurate measurements and enables individual consumption billing. 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 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).
