Compact 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 is also suitable for difficult Utility installations (IP68). Activation and configuration of the multiprotocol radio are carried out locally using the NFC interface and a dedicated Android app.
wMBus and LoRaWAN™ radio module for the ISM 868 MHz band, featuring a built-in inductive pulse sensor. Compatible with Maddalena meters in the MVM range from DN 15 to DN 40. 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 systems. Battery powered, with a battery life of up to 15 years (depending on the type of configuration and the number of readings/transmissions).
Direct installation on the meter, including anti-tampering seals. The totalizer and the information on the face are accessible after opening a protection lid. Activation and configuration are carried out locally using the NFC interface and a compatible Android app.
