Wireless Ultrasonic Water Meter

Ultrasonic water meter with wireless WM-Bus or LoRaWAN communication

The remotely read, wireless ultrasonic water meter measures water consumption accurately from the very first drop. With no moving parts, it is highly reliable, long-lasting and retains its measurement accuracy year after year. The battery-powered meter runs for up to 16 years without maintenance and sends consumption data automatically to the cloud over a WM-Bus or LoRaWAN network. It makes water consumption easy to monitor and detects any leaks or anomalies quickly. This helps reduce water waste and keep costs under control.
