Compact wM-Bus radio module for drive-by and fixed network remote data reading. Also available in a standalone version for connection to compatible pulse emitting meters. Arrow EVO is also suitable for difficult Utility installations (IP68). The configuration of the radio module can be changed using a dedicated configuration kit (optional) and Android app.
Compact radio module with built-in bidirectional inductive sensor, designed for Maddalena MVM, MVM PLUS C and WMAP EVO water meters. Add-on version also available. It mounts on compatible pulsed meters. Designed for reading remotely consumption data and alarms, ensuring ease and efficiency. It is ready for use and the factory settings enable both mobile (walk-by) and fixed (AMR) reading. The factory settings can be changed locally via radio with the configuration kit (optional).
Based on the inductive principle, which ensures insensitivity to magnetic interference fields, the internal sensor of ArrowEVO detects the revolutions of the meter’s pointer, calculates the volume (in both directions) and manages the alerts. The module manages the following alarms: overflow (the threshold must be activated and can be configured), backflow (threshold set, can be configured), leak, meter blocked or non-used (days threshold set, configurable), magnetic and mechanical tampering (removal). ArrowEVO complies with the wM-Bus data communication protocol regulated at European level by the standard EN 13757. This ensures interoperability with different reading systems, as well as by third parties.
