IZAR PASSIVE DRIVE-BY BOX 2 Light is a radio data concentrator pre-equipped with antennas and embedded in a rugged box specifically designed for passive drive-by meter reading.
IZAR PASSIVE DRIVE-BY BOX 2 Light is easy to install on any type of maintenance or waste truck vehicle. Powered by the vehicle electrical circuit it enables autonomous reading of every communicating multi-energy meters and sensors (water, thermal energy, gas, electricity...) based on OMS specifications, with automatic data export via a mobile network.


  • Available in 868 MHz or 434 MHz
  • Automatic reading of meters
  • Multi-energy solution (water, thermal energy, gas, electricity...)
  • Data transfer to a FTP or SFTP server
  • Data sending via 2G/3G
  • Local or remote configuration
  • Principle of operation

    IZAR PASSIVE DRIVE-BY BOX 2 Light receives radio telegrams according to the EN 13757 standard and OMS (Open Metering System) specification, regardless of the type of meters or sensors (water, thermal energy, gas electricity, temperature, humidity…).
    Data is then transferred automatically via the mobile network (2G/3G) to a FTP or SFTP data storage server to be processed by the Diehl Metering software solutions IZAR@NET 2 or IZAR PLUS PORTAL.
