Ultrasonic Flow Measuring System
Flowrate measurement for standard applications with drinking water and process water

Your benefits
The Prosonic Flow ultrasonic clamp-on system allows accurate and cost-effective flow measurement from outside the pipe and without the need to interrupt the process. The flow measurement is bidirectional and causes no pressure loss.

  • Easy, safe and menu-guided sensor mounting ensures precise measuring results
  • Long-term system integrity thanks to robust sensor and industrial mounting kit design
  • Automatic frequency scan for optimized installation and maximum measuring performance
  • IP 68 for pipes under water

  • Can be used with all metal and plastic pipes lined or unlined
  • Ideal solution for applications with water, e.g. drinking water, industrial water, saltwater, deionized water, cooling water and heating water
  • Perfectly suitable for
    • subsequent mounting
    • flow monitoring
    • improving measuring points
