    Residential Ultrasonic Water Meter (DN15 to DN40) is designed for residential smart water metering. It is operated by battery.
    Residential Ultrasonic Water Meter (DN15 to DN40) Features:
    • Ultrasonic signal quality detection
    • Low initial flow rate and min. flow velocity measured is 0.002m/s;
    • No mechanical moving parts, long service life
    • Water temperature detection, low temperature alarm
    • Abnormal water usage alarm
    • High-precision machining centers, initiating action to prevent the occurrence of product non-conformity, stable and reliable
    • IP68 of the whole meter, for each unit of the meter is IP68 designed; mounting, immune to any impact on measuring and pressure dropping to a minimum meanwhile
    • Complies to MODBUS RTU and EN13757 communication protocol
    • Adaptable to inferior water quality, low in maintenance cost
    • Ultralow power consumption, battery with over 10-years(DN15-40, less than 0.0008W
    • Support optical, RS485 and M-BUS (wired & wireless) communication interface; available in remote reading(AMR), and easy for central control and management
    • Approved according to GB/T 778-2007 and MID certification
    • Advanced calibrating device, adopt international advanced automatic heat meter calibration device, ensure the product accuracy
    • Comply to drinkable water standard requirement
