TDR sensor for continuous level measurement 

Application area

The VEGAFLEX 66 is a level sensor for measurement of liquids and bulk solids at high pressures up to 400 bar and temperatures up to 400 C. The VEGAFLEX 66 delivers reliable and high precision measured values unaffected by ambient influences such as dust, steam, buildup and condensation. This sensor is the high-quality solution for sophisticated applications in the chemical and petrochemical industry as well as power generation.


  • 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
