Separate wMBus and LoRaWAN™ radio module, ensuring a high level of interoperability with a range of mobile and fixed network reading systems, including third-party ones. Arrow WAN 2 split is also suitable for difficult Utility installations (IP68). Compatible with all Maddalena pulse emitter modules.
Separate wMBus and LoRaWAN™ radio module for the ISM 868 MHz band for water meters equipped with pulse sensor. Compatible with all Maddalena meters from DN 15 to DN 300. Data communication protocol compliant with the OMS wMBus (EN 13757) and LoRaWAN™ standards. The multiprotocol radio guarantees a high level of interoperability with a range of mobile and fixed reading systems, including third-party ones.
Battery powered, with a battery life of up to 15 years (depending on the type of configuration and the number of readings/transmissions). Activation and configuration are carried out locally using the NFC interface and a dedicated Android app.
