SITRANS FUH1010 Interface Detection (Oil)


The SITRANS FUH1010 clamp-on non-intrusive ultrasonic interface detector  is ideal for oil applications that require differentiation between various liquids in a pipeline and determination of liquid quality.

The interface detector is available in single and dual channel/path configurations. There are two enclosures to choose from: wall mount and wall mount explosionproof.

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

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
