BioProTT Flow SU System

Our innovative plug & play solution to simplify flow measurement processes in biopharma single-use applications.

  • Seamless Integration & Smart Connection
  • Easy Spec-in & Easy Order Handling
  • High Level of Features & Low Level of Maintenance

Easy to Integrate

Our innovative BioProTT FlowSU can be easily integrated into your bioprocess as the sensor can be exchanged from the system without any complicated tools.

Advanced Technology

Our BioProTT FlowSU features ultrasonic technology allowing for flow measurement and air-in-line detection in one single-use flow sensor.


The BioProTT Flow SU consists of a disposable single-use flow sensor and a mounted reusable holder to make up the BioProTT FlowSU System. The combination of these two parts allows for easy integration into single-use manifolds. The BioProTT Flow SU features the first single-use exchange sensor with no need for calibration. Featuring smart connection, once connected to the holder, only one cable is needed to get accurate measurments.

Once the system is powered and the Modbus TCP interface is set up, the sensor can be attached to the holder. Integrated electronics automatically detect the sensor size and select the correct parameter set stored in the multi-use part. The digital interface indicates when the flow path has been primed. After zeroing, the measurement can be started. As with priming, the sensor can be used as an indicator when the path is running dry. Removing the sensor at the end of the process is as easy as attaching it and requires no additional tools.
