Radio | Radio Module

Application

IZAR Radio Compact Inductive R4 is designed for mobile reading and long-range fixed network remote reading of Diehl Metering water meters. IZAR RC i R4 radio module can be clipped onto all the meters of the Diehl Metering inductive modular range (Ha+Ti or Ti) with a grey or red ring. It comprises a tamper proof sensor operating on inductive principle.
Easy to fit, IZAR RC i R4 is field or factory programmable with the serial number of the associated meter. IZAR RC i R4 radio module transmits the meter reading via a unidirectional link every 8 seconds in R3 mode and every 15 minutes in long-range fixed network R4 mode, enabling an efficient drive-by reading at 50 km/h and an accurate fixed network.
IZAR RC i R4 offers multiple functions (historical index value, remaining battery lifetime...) and alarms (leaks detection, meter stopped, backflow...).

  • Insensitive to magnetic fraud
  • Principle of operation

    IZAR RC i R4 includes an electronic circuit that collects the data coming from a Diehl Metering water meter and transmits in real time the index and other operating information every 8 seconds in R3 mode and every 15 minutes in long-range fixed network R4 mode.

    Mobile reading in Walk-by / Drive-by / Passive Drive-by:
    The data sent by IZAR RC i R4 is collected using either a handheld computer or a tablet equipped with an IZAR RECEIVER BT for Walk-by/Drive-by or an IZAR RDC VEHICLE for passive Drive-by. Data is then transferred directly to a centralized monitoring system.

    Fixed network:
    A fixed receiver IZAR RDC STANDARD/IZAR RDC BATTERY (fixed network R3) or IZAR RDC PREMIUM (long-range fixed network R4) installed in a building will collect the data and send it at predefined intervals via GPRS or LAN, to a centralized server.
