  • Principle of operation

    The IZAR RDC Premium 2 receives radio telegrams according to EN13757 and the Open Metering System Specification (OMS-S) independent of the measured medium. These are saved on the basis of a filter function (e.g. according to medium or manufacturer). The collected and processed data are exported in flexibly settable intervals or time points in a fully automatic and secure way to IZAR@NET or other systems which can upload the files for further processing. All this happens automatically upon schedules configured in every gateway.
