The interface detector is available in single and dual channel/path configurations. There are three enclosures to choose from:  wall mount, wall mount explosion proof and compact explosion proof.


Application examples include interface detection, product identification, density indication and "pig" detection.


Pair the SITRANS FUH1010 interface detector with the SITRANS F US Thickness Gauge to ensure precise flow measurement.


  • Allows direct replacement of intrusive densitometers with liquid density and API number outputs
  • Maintains exceptional repeatability independent of changes in temperature, density or viscosity
  • Eliminates straight run piping requirements
  • Reduces capital cost by inferring density, alleviating need for additional equipment
