BioProTT™ Clamp-On SL

The BioProTT™ Clamp-On SL in combination with a corresponding evaluation device (BioProTT™ FlowTrack SL or a BioProTT™ FlowMCP variant) ensures a reliable and precise measurement and monitoring of flow rates on liquid-bearing tubing systems in industrial applications.

With its simple click-fasting, the sensor can be quickly and easily attached to flexible tubes. The lack of movable parts and functional design, paired with the non-invasive measurement method, prevents additional shear stress for the medium. When it comes to handling shear-sensitive organisms or biomolecules, this is an essential advantage.

The ultrasonic transit time method - combined with a customer-specific calibration regarding the respective process parameters allow for a highly accurate measurement an represents a flexible solution for your application.

As an additional tool, the new BioProTT™ Clamp-On Bracket enables more convenience and flexibility for an easy mounting of large, multi-use sensors on complex skids.

For the flow measurement on flexible tubes on upstream and downstream applications such as:

  • Chromatographies
  • Adding media to bioreactors
  • Filtration
  • Fillings
  • Process evaluation
  • Upscaling
  • Research

Key Facts

  • Easy installation
  • Non-invasive flow measurement
  • Different sensor sizes for all commonly used tube sizes ranging from
    1/4'' to 1-5/8'' outer diameter
  • No additional shear stress on cells through the non-invasive design
  • Re-usable and long-lasting
  • Customer-specific calibration to tube, medium, temperature, and maximum flow rate
  • Up to seven calibration tables storable on one sensor - for maximum flexibility
  • Easily cleaned with commonly available disinfectants
  • Easy mounting of large, multi-use sensors (with the BioProTT™ Clamp‑On Bracket).


When installing large multi-use sensors directly onto complex skids, the exchange of the sensor can be cumbersome and time-consuming.

Simplify this step with the new BioProTT™ Clamp-On Bracket. The advantages are obvious:

Simple Mounting

  • Just 4 screws to fix the bracket
  • Flexible mounting options

Easy Exchange

  • Quick click mechanism for the sensor setup & exchange

Clear Arrangement

  • Less assembly effort after sensor exchange
  • More order for a clear layout to the skid
