DMTFB Clamp-on Series Ultrasonic Flowmeter

  • The DMTFB Ultrasonic flowmeters provide abundant capabilities for accurate liquid flow measurement from outside of a pipeline
  • It utilizes state-of-art technologies on ultrasonic transmission / receiving digital processing and transit-time measurement
  • The proprietary signal quality tracking and self-adapting technologies allow system to adapt to different pipe materials automatically
  • Clamp-on design makes the transducer installation easy and no special skills or tools required
