B-meters IWM-TX3 Wireless M-BUS radio module GMDM-I, GMB-I, GMB-RP-I and CPR-M3-I
The IWM-TX3 is a WMBUS radio module for the transmission of consumption data that is compatible with the GMDM-I, GMB-I, GMB-RP-I, and single jet mod series of multijet water meters. CPR-M3-I.
In addition to providing data on recent consumption and a history of up to 12 months, it also enables the detection of potential water leaks downstream of the meter, prolonged operation at maximum flow rate (Q4), and various sorts of attempted meter fraud.
