Features

Building Ultrasonic Water Meter(DN50 to DN1000) Features: 

  • Approved according to GB/T 778-2007 and MID certification(DN15 to DN600)
  • 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
  • Abnormal water usage alarm
  • Water temperature detection, low temperature alarm
  • Low starting flow rate, minimum flow rate is 1/3 traditional water meter
  • High-precision machining centers, initiating action to prevent the occurrence of product non-conformity, stable and reliable
  • Adaptable to inferior water quality, low in maintenance cost
  • Ultrasonic signal quality detection
  • Low initial flow rate and min. flow velocity measured is 0.002m/s;
  • No mechanical moving parts, long service life
  • Ultralow power consumption, battery with over 10-years(DN15-40) & 6-year life time(DN50-600 Flanged type); 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
  • Complies to MODBUS RTU and EN13757 communication protocol
