Meet the new ADDRA ultrasonic water meter with an integrated shut-off valve — a smart, maintenance-free solution for advanced water control.
With an ultra-low starting flow of just 1 l/h, it detects even the smallest leaks. The IP68 housing ensures reliability in underground and flood-prone areas.
The meter automatically connects to the best available network, supporting NB-IoT, LoRaWAN, and Wireless M-Bus — all in one device. Local access via BLE and NFC simplifies installation and service.
It features built-in alarms for leaks, bursts, tampering, backflow, and dry pipes, and supports both credit and STS-based prepaid modes.
Accurate, future-ready, and easy to install — the ADDRA meter is built for smart cities and efficient utilities.
In case of emergencies, the meter reacts instantly: in the event of a leak or burst pipe, the valve automatically shuts off the water supply to prevent losses. In cases of tampering, reverse flow, or dry pipe — the system sends an alert to the operator and logs the event. Management is possible remotely or via BLE/NFC — simple, reliable, and secure.
