TDR sensor for continuous interface measurement 

Application area

The VEGAFLEX 67 is a level sensor for continuous interface measurement. Typical applications are oil/water interface measurements in separators. Due to the software optimized on interface applications, the sensor is the ideal solution for use in all industries. The VEGAFLEX 67 works independent of ambient influences such as steam, buildup and condensation as well as the density of the liquid.


  • Minimum time and cost expenditure thanks to simple setup without medium
  • Simple instrument selection, because independent of product features
  • Low maintenance costs, because wear and maintenance-free
