IZAR RDC BATTERY Light is a concentrator specifically designed for fixed network meters reading.
IZAR RDC BATTERY Light reads every communicating multi-energy meters (water, thermal energy, gas, electricity…) and sensors equipped with the IZAR radio technology. It then transmits the data to a data storage server at preset times. IZAR RDC BATTERY Light can manage up to 4,000 meters with the data directly processed using IZAR@NET 2 or IZAR PLUS PORTAL software.
IZAR RDC BATTERY Light is fully autonomous in energy thanks to a battery pack easily replaceable on site. An external connector enables the use of another source of energy, such as a solar one. Moreover, equipped with a SD memory card, it can operate in “data logger” mode for a more accurate analysis of the data (consumption profiles, leakage detection…).

  • Operating principle

    IZAR RDC BATTERY Light receives radio frames according to the EN 13757 standard and the OMS specification (Open Metering System), regardless of the type of fluid measured (water, thermal energy, gas, electricity, temperature, humidity…). Intelligent data filter options can be activated in order to precisely target the reading on defined meters, in particular by fluid type or manufacturer. The data transfer to an FTP or SFTP storage server is performed automatically through programming, either at regular intervals or at fixed date/time. The Diehl Metering software solutions IZAR@NET 2 or IZAR PLUS PORTAL enable the processing and exploitation of this data.
