IWM-LR3 is a LoRaWAN radio module for the transmission of consumption data, applicable to the series of multi jet water meters mod. GMDM-I, GMB-I, GMB-RP-I and single jet mod. CPR-M3-I.

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

IWM-LR3 thanks to the Long Range LoRa radio technology and the compliance to the LoRaWAN standard can be integrated into multi-service networks.
