  • Principle of operation

    The IZAR RECEIVER M-BUS receives radio telegrams from IZAR RADIO or Open Metering meters and stores them into its internal memory. Each time a new radio telegram is received, the IZAR RECEIVER M-BUS deletes the old one from that meter. The IZAR RECEIVER M-BUS can only be used in combination with an IZAR CENTER M-Bus master and IZAR@NET 2 software. Here it is possible to do an interval reading like it is done with a normal M-Bus meter. The data stored in the IZAR CENTER memory must be transferred to IZAR@NET software.
