RS-485 portable clamp-on type Wall-mounted ultrasonic flow meter

The ultrasonic flow meter is designed to measure the fluid velocity of liquid within a closed conduit. The transducers are a non-contacting, clamp-on type, which will provide benefits of non-fouling operation and easy installation.

RS-485 portable clamp-on type Wall-mounted ultrasonic flow meter

Working principle

Wall-mounted ultrasonic flowmeter utilizes the principle of low voltage and multi-pulse time difference. It adopts high-precision and ultra-stable double-balanced signal scoring and differential receiving digital detection technology to measure the sound wave transmission time in the forward and reverse flow directions. Calculate the flow rate. It has a very simple installation method, no need to break the pipe, no need to stop water, so that customers can easily realize flexible pipe flow measurement. The product can also be equipped with mounting fixtures that eliminate the need for routine maintenance and provide reliable, drift-free measurements over the long term. It uses advanced digital correlation technology and intelligent adaptive sound wave technology, which is more stable in its measurement stability. At the same time, it uses the sound focusing technology to significantly enhance the signal reception quality of the product during continuous measurement.

Wall-mounted ultrasonic flow meter product features:

  • Unique SMT automatic chip circuit to ensure high quality product performance and low maintenance rate
  • full menu software design, through the menu can easily set the pipe diameter, pipe material, wall thickness, output signal and other parameters or types
  • can automatically remember positive and negative net cumulative flow
  • electrically isolated 0-20MA or 4-20MA current loop output
  • isolated DC8-36V or AC85-264V multi-channel input and output.

Order notice: 

  • The measured medium should not contain more ferromagnetic substances and a lot of bubbles, otherwise it will affect the measurement accuracy;
  • The user shall clearly specify to our company the medium to be measured and its flow range, working pressure and fluid temperature, and select the appropriate flow meter according to these parameters;
  • If the user needs to install accessories, such as supporting flanges, gaskets, bolts, nuts, washers and other additional requirements, can ask when ordering.
