The new modules IZAR MBUS COMPACT i are the center of the modular inductive concept developed by Diehl Metering. They can be clipped onto all the meters of the Diehl Metering inductive (Ti) or mixed (Ha+Ti) modular range with grey ring, making them "communicative" in a very easy way.
IZAR MBUS COMPACT i provide informations using M-Bus protocol (EN 13757), enabling billing (index…), monitoring (flow rate, direction…) and the management/follow-up of the installation (tampering, cable cut-off and unclipping alarms ….).
It may be connected to different systems such as M-Bus or fixed networks, monitoring, or consumption-analysis systems.
IZAR MBUS COMPACT i feature a clamping ring for totally secured mounting (sealable cam) and easy reinstallation on another meter.
