IZAR RADIO COMPACT ACM

IZAR RADIO COMPACT ACM

RADIO | RADIO MODULE

Radio compact module for diaphragm gas meters with Absolut-ENCODER AE2/AE3 interface. Usable for optimum reading with difficult access.

  • Simple installation with stand-by mode
  • Transmission of real meter data by radio to mobile or stationary receivers
  • Storage and transmission of one due date value (e.g. last of month)
  • Protocol according to OMS-S v3 / OMS-S v4
  • On-site-programming using IrDa interface
  • Battery powered with a lifetime of up to 12 years
  • Principle of operation

    The IZAR RADIO COMPACT ACM consists of an electronic unit, which receives and saves meter information in the form of real data. The radio module sends the meter number, meter reading and various items of operating information in a defined sending scheme. The data can be received by a mobile or static receiver.

    Mobile: The IZAR@MOBILE 2 TABLET collects the data in walk-by or drive-by mode in conjunction with the IZAR RECEIVER BT. The data for the reading route is sent directly to the central PC.

    Static: An IZAR RADIO DATA CONCENTRATOR (IZAR RDC) collects and saves the data and transfers it cyclically to a control centre.
