IZAR RC IoT LRW WMB

RADIO MODULE

Application

The IZAR RC IoT LRW wMB radio module integrates LoRaWAN® technology for fixed network and wireless M-Bus for mobile reading. IZAR RC IoT can be easily clipped onto all modular Diehl Metering meters in the inductive range (Ha+Ti or Ti) equipped with a grey or red ring*. IZAR RC IoT has a built-in inductive sensor that makes it insensitive to magnetic fraud. Furthermore, it can be used with a pulse-emitting meter when combined with our IZAR BE PULSE interface for billing. IZAR RC IoT is integrated into IZAR LoRaWAN® solution with software and accessories.

  • Operating principle

    IZAR RC IoT LRW wMB includes an electronic circuit that collects the data coming from a Diehl Metering modular water meter. It transmits the index and other operating information in fixed network and via mobile reading. Fixed network:IZAR RC IoT LRW wMB operates in LoRaWAN® fixed network. The radio module complies with the LoRaWAN® Specification 1.0.4 in Class A, supporting Adaptive Data Rate (ADR) and Over The Air Activation (OTAA). The radio module data are sent via a proprietary protocol over LoRaWAN® with meter data redundancy. A profile allows the radio module to send the current index and alarms according to the TR06 OMS Over LoRaWAN®.Mobile reading:IZAR RC IoT LRW wMB sends wireless M-Bus frames for mobile reading. The radio module data are sent via wM-Bus C-Mode. The radio module can be configured locally via C2.The modules logs can be retrieved on-demand:- 1/4-hourly consumption values- Hourly consumption values- Midnight index values- Monthly index values (midnight index of the last day of the month)

  • Technical data
    Communication Protocol for Fixed NetworkOMS over LoRaWAN® (TR06) for current Index and Alarms. Proprietary protocol for extended data over LoRAWAN®
    Sending interval in Fixed NetworkLast midnight index sent every 12 hours - Last 16 hourly consumption values sent every 8 hours - Last nightline consumption values sent every 12 hours - Event frame triggered by one of the four major events immediately sent with 3 repetitions
