CM Series Clamp-on Ultrasonic Flow Sensor

 

CM series clamp-on ultrasonic flow sensors are compact in size, and can measure flow and output results without external circuitry. 

The sensors can be directly clamped on flexible plastic tubing to accurately measure the liquid flow rate and detect air bubbles. The sensors are not in direct contact with the liquid in the tubing and will not contaminate the liquid. They are especially suitable for applications where strict hygiene is required, such as biopharmaceutical processes, medical equipment, and semiconductor manufacturing.

 

 

Features

  • High precision and high stability
  • Non-invasive measurement, no direct contact with liquid, hygienic safety
  • Bi-directional measurement, can calculate fluid volume and detect air bubble
  • Circuit embedded in the sensor and no external circuit is required
  • No blockage, no dead area, low fluid pressure loss
  • Provide standard output methods to seamlessly integrate with customer systems
  • Customized calibration of plastic tubing material, size, temperature, and liquid type

 

 

Applications

  • Medical devices such as hemodialysis machines, organ transplantation systems, heart-lung machines, blood pump
  • Biopharmaceutical processes and equipment, such as single-use systems, fermenters, cell culture equipment, vaccine production, tangential flow filtration systems, liquid chromatographs
  • Fluid monitoring during semiconductor manufacturing, such as high-purity water and corrosive chemicals
  • Food & beverage processing, such as milk, juice, and beer production
  • Filling equipment, spraying equipment, cooling system, lubrication system
  • Scientific experiment system
  • Water treatment and wastewater treatment system
