ADR 32 is a compact ultrasonic water meter designed for installations where space efficiency and high accuracy are equally important. Despite its shorter body length, the meter delivers extremely high metrological performance across the entire measuring range, including very low flow rates. The ADR 32 integrates advanced communication capabilities with an intelligent adaptive power system, ensuring stable and reliable data transmission within smart metering infrastructures. The meter supports multiple communication technologies — NB-IoT, LoRa, and WM-Bus — integrated within a single device. These communication modes can be switched depending on project requirements, network availability, or operational conditions, providing maximum flexibility and reliability in diverse deployment environments. A key advantage of ADR 32 is its replaceable powerbank module. The battery unit can be changed independently, allowing the service life of the meter to be extended without replacing the entire device. This significantly reduces operational costs, minimizes maintenance efforts, and supports long-term sustainability strategies.
