IWM-LR5: LoRaWAN module for water meters with INDUCTIVE predisposition

IWM-LR5 is a wM-BUS and LoRaWAN radio module suitable for transmitting consumption data and applicable to GSD8-I single-jet water meters.

In addition to current consumption information, it can detect different types of fraud attempts against the meter, prolonged operation at maximum flow rate (Q4), and the presence of a potential water leak downstream of the meter.

The IWM-LR5 has been designed to allow data reading without on-site intervention, in walk-by or AMR (automatic meter reading) mode, in compliance with the wM-Bus standard. It also supports reading via Long Range LoRa radio technology, in compliance with the LoRaWAN standard, making the device integrable into multi-service networks.
