    KARAT-Compact-223 is intended for energy measurement in almost all types of thermal installations where water is used as the energy-conveying medium.

    Ultrasonic measuring method

    The turndown of 1:200, which is wider as compared to the velocity flowmeters turndown.
    Measurements stability during the whole operation lifetime.

    LoRaWAN or M-Bus ready

    KARAT-Compact-223 is comes with option of being read remotely using LoRaWAN or M-Bus.
    Wired M-Bus or wireless LoRaWAN is integrated in the meter for remote data reading.
