Water Meter, District

uFlow 340 SERIES (DN50-600)

1. Introduction

The uFlow 340W series compact type ultrasonic water is an innovative flow meter with static flow sensor based on the ultrasonic measuring principle. It 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.

2. Features

  • Water temperature detection, low temperature alarm
  • Abnormal water usage 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
  • Ultra low power consumption, battery life of over 10 years (DN15-40) & 6 years (DN50-600); less then 0.0008W
  • Support optical, RS485 and M-BUS (wired & wireless) communication interface
  • Complies to MODBUS RTU and EN13575 communication protocol
  • IP68 design

3. Application

  • Residential water meter
  • Tenant billing
