Flow Measurement, Flowphant T DTT31/35


  • Flow switch for monitoring and displaying relative mass flow rates of liquid media in the range from 0.03 to 3 m/s (0.1 to 9.84 ft/s).
  • Flowphant T DTT31 − with thread connections or coupling.
  • Flowphant T DTT35 − with process connections for hygienic applications.


Flow switch for the measurement and monitoring of mass flow.

The Flowphant T liquid flow switch measures the mass flow of liquid. Using the thermal principle, it measures liquid flow rates in the range of 0.03 and 3m/s with exceptional accuracy. Complete with a robust stainless steel housing, Flowphant is suitable for even the most harsh environments. In addition, the legend plate is laser printed directly on the device, making the important information such as the serial number, order code and tag number easily accessed and secure. The rotatable housing and illuminated display ensures data is simple to view and monitor and in the event of an error, the display changes colour from white to red, so you can immediately recognise switch-point errors.
