    RBBH DN15-40 Residential Ultrasonic Heat Meter (BTU meters), Thermal Energy Meters, HVAC Metering, smart meter

    RBBH DN15-40 Residential Ultrasonic Heat Meter (BTU meters) is an innovative heat meter with static flow sensor based on the ultrasonic measuring principle. RBBH Ultrasonic Heat Meter (BTU heat meter) is designed for measuring the use of heating in which water is the heat-bearing medium. RBBH Ultrasonic Heat Meter utilizes ultrasonic measuring methodology and microprocessor technology. All calculation and flow measuring circuits are designed on one single board, thus offering exceptional accuracy and reliability.

    Residential Ultrasonic Heat Meter (DN15 to DN40) Features:

    • Certificated by CMC and MID and conform to CJ128-2007 and EN-1434 norm.
    • High capacity 3.6V lithium battery inside, above 8/10 years shelf life
    • Dynamic range of 250:1, 100:1 & 50:1
    • Unique design for calculator can be adjusted within 0°~120°in vertical and can be rotated within 0°~350°in horizontal, convenient to read data from different direction(only for 12 series)
    • Can be mounted in flow pipe or in return pipe, and can be mounted in horizontal and vertical
    • No straight piping requirements for DN15-DN40 meter installation, support flow and return water installation, even if horizontal and vertical installation, can be mounted at any angle.
    • Complies to MODBUS RTU and EN13757 communication protocol
    • Support optical, RS485 and wired & wireless M-BUS interface, convenient for user to manage data in different manners.
    • Support multiple communication modes, 2 pulse in 1pulse out, 4-20mA, GPRS functions(Only for 2 series)
    • Advanced calibrating device, adopt international advanced automatic heat meter calibration device, ensure the product accuracy;
    • Can be used as cooling, heating or combined climatic meter;
    • The modular design, support and flange connections
