    Characteristics

    KARAT-Compact-223 is intended for energy measurement in almost all types of thermal installations where water is used as the energy-conveying medium.
    The heat meter employs the highly accurate ultrasonic technology. Every drop is measured due to the dynamic range of 250:1 reducing loss of distributed energy.
