B-meters IWM-MB3 Wired M-BUS module GMDM-I, GMB-I, GMB-RP-I and CPR-M3-I

The IWM-MB3, which is suitable to the series of water meters models GMDM-I, GMB-I, GMB-RP-I multi jet, and mod. CPR-M3-I single jet, is an integrated module for the transmission of consumption data via cable M-BUS network.

It is simple to install and set, and in addition to providing data on current consumption, it enables the detection of potential water leaks downstream of the meter, prolonged operation at maximum flow rate (Q4), and many sorts of attempted meter fraud.

The application is immune to the vibrations of the pipes thanks to the employment of an inductive target in the meter dial, which also eliminates the potential of magnetic fraud.
