Ultrasonic Meter Type

BTU Meter / Flow Meter, District

uFlow 230 SERIES

1. Introduction

The uFlow 230 series ultrasonic BTU meter can be used for measuring the energy consumption in heat / cooling application for billing purpose. The measurement principle is static and based on the measurement of transit time with pair of ultrasonic transducer propagating at each other upstream and downstream. All calculation and flow measurement circuits are designed on one circuit board, thus offering exceptional accuracy and reality.

2. Features

  • High capacity 3.6 lithium battery inside, above 8 till 10 years shelf life
  • Dynamic range of 250:1, 100:1, 50:1
  • Can be mounted in flow pipe or return pipe, and can be mounted horizontally or vertically
  • Support optical, RS485 and wired & wireless M-bus interface, convenient for user to manage data in different manners
  • Complies to Modbus RTU and EN13757 communication protocol
  • Certified by CMC and MID
  • Advanced calibrating device, adopt international advanced automatic heat meter calibration device, ensure the product accuracy
  • Can be used as cooling, heat or combined climatic meter
