The IWM-MB4 is an integrated module, for the transmission of consumption data via cable M-BUS network, applicable to the series of water meters mod. WDE-K50 woltmann.

Easy to install and configure, 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.

The use of an inductive target in the dial of the meter excludes the possibility of magnetic fraud and makes the application insensitive to the vibrations of the pipes.
