Cable remote ultrasonic water-meter

Cable remote ultrasonic Water Meter

Models:LXCN-15/20/25/32/40       

Usage:Figuring out the water flow speed by measuring the ultrasonic wave velocity of change that caused by water flow in the pipe, then, obtain the volume of water passed by. Ultrasonic water meter is a credible instrument for trade settlement.


  • Features

  1. Low start flow, long range of measurement

  2. Counting forward and reverse flow, pinpoint accuracy and stability

  3. Low power design & long battery longevity

  4. Equipped with leaky detection & burst detection

  5. Varieties of communication model, wired M-bus network, radio Ad-Hoc network, Bluetooth with smartphone APP can be selected as need, easy to access the meter’s data for monitoring

  6. Large-capacity data storage, recording meter’s running information including 36 months of time-slicing information for the district metering monitoring

  7. No wear & no moving parts, low head loss

  8. Strengthen design for waterproof, IP68 type tested, suitable for installation in meter pits

  9. Can be fixed in almost any direction, not must to be vertical or horizontal
