Wireless M-BUS OMS module for multi jet meters with inductive interface

IWM-TX3 has been designed to allow wireless remote reading in different types of applications from the residential sector to the commercial and industrial sectors.

The radio module thanks to the presence of the inductive target into the meter dial allows the reading of the volume consumption without any constraints of access to the site in walk-by mode or AMR (automatic meter reading), in respect of the WMBUS standard and complying with the OMS (Open metering system) specification.

Consumption analysis with reverse flow compensation that provides an always perfect alignment between the totaliser and the meter.

Fraud control (removal of the radio module, application of external magnetic field, reverse flow, identification of system loss). Magnetic tampering to the meter and removal are recorded and reported to the receiving system via radio transmission. The presence of reverse flow is recorded in an additional register that allows to calculate the amount of water passed in reverse. The loss function can be monitored at the time of reading or by the AMR system if a timely update is desired.

IP68 protection* allows the use of the module also for meters installed in difficult environments.

NFC interface allows configuration and commissioning of the device with the use of a simple smartphone app.
