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.
Radio module available in a compact version with inductive sensor for direct mounting on the meter, or in a separate version with pulse input, ideal for making any meter equipped with a compatible pulse output smart. Data communication takes place via the wM-Bus network (EN 13757) and the LoRaWAN™ network, ensuring high interoperability with mobile and fixed reading systems and high transmission reliability.
The radio technologies used ensure long-range coverage and reduced energy consumption, making the module suitable for urban, suburban and rural environments. Power is supplied by a battery with a service life of up to 15 years (depending on the configuration type and the number of readings/transmissions). Activation and configuration are performed via local NFC interface and the related Android app.
The module is designed for direct installation on Maddalena MVM DN 15–DN 40 meters; it allows visual access to the totalizer and dial markings.
5-wire pulse input with option for installation on a bracket for pipe mounting, wall mounting or integral mounting on a Maddalena E-BULK meter.
