WMB-R

WMB-R is Advanced Wireless M-Bus / LoRaWAN Module for Smart Water Metering.

The WMB-R is a compact,high-performance RF module for wireless transmission of metering data over the Wireless M-Bus communication protocol or LoRaWAN standard protocol formulated by the LoRa Alliance.

WMB-R module scans the dedicated counter indicator of the water meter, using an induction system to detects and recognises its direction of rotation, which enables accurately reflect the actual reading of the water meter counter in pulse signals.

With real-time flow monitoring, instant leak detection, and automated alerts for abnormal usage, the WMB-R empowers utilities and building managers to prevent waste, optimize effciency, and reduce costs. Its ultra-compact design and tool-free replacement make maintenance effortless, while secure remote data access enables smarter, data-driven decision-making.

Simplify water management with the WMB-R
