The ADD Grup ADR is an ultrasonic water meter available in DN15, DN20, and DN25 sizes. It is wear-free, highly accurate (Class 2), and capable of measuring flow rates as low as 1 L/h. It offers IP68 protection, is suitable for indoor and outdoor installation, and records volume, flow rate, and temperature, as well as triggering alarms in the event of leaks, pipe breaks, dry running, backflow, or tampering. Communication is via LoRaWAN, NB-IoT, Wireless M-Bus, and locally via NFC and BLE. Flexible power supply via internal or external batteries and a super pulse capacitor enables reliable remote monitoring and smart water applications.
The sensor is factory-configured for LoRaWAN. If you prefer a different connectivity option, you can configure the parameters yourself. The sensor ships with the following default configurations:
ADR15, 110 mm, Q3 2.5, R800, T50
ADR20, 190 mm, Q3 4, R800, T50
ADR25, 260 mm, Q3 10, R800, T50
Other flow rates and temperature class T30 are available upon request. In this case, please contact our back office.
