IWM-MB3

Wired M-BUS module for multi-jet water meters with inductive interface

The BMETERS IWM-MB3 is suitable for remote reading in residential, commercial and industrial applications. This M-BUS module allows the meter consumption data collecting by using the standard Wired M-BUS protocol, historically developed for remote meters reading.

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

The IWM-MB3 is compatible with all the pre-equipped multiple jet meters (wet, semi-dry and dry dial) and provides:

  • Consumption analysis with reverse flow compensation.
  • Fraud detection (removal of the module, external magnetic field tampering, reverse flow, water leakage). All the alarms are recorded and reported into the M-BUS telegram sent by the module.
  • IP68 protection* allows the installation of the module even in harsh environments.
  • NFC interface allows configuration and commissioning of the device with the use of a simple smartphone app.
