2-wire Guided Radar (TDR) Level Meter

OPTIFLEX 2200 C / F Guided Radar (TDR) Level Meter

The modular TDR solution

  • Modular design of housing and probe ensures suitability for a variety of mounting positions and applications
  • Universal measurement device for liquids and solids
  • SIL2-compliant according to IEC 61508 for safety-related systems

This device is a TDR Level Meter for measuring distance, level, volume and mass. Its modular design makes it an economical and reliable solution for common applications.


  • 2-wire loop-powered HART® TDR level meter for liquids and solids
  • DPR (Dynamic Parasite Rejection): the software dynamically eliminates false reflections caused by environmental disturbances and product build-up
  • Quick coupling system permits removal of the converter under process conditions and 360° rotation to make the display screen easier to read
  • Horizontal or vertical housing position to suit every installation
  • The remote converter can be installed up to 100 m / 328 ft from the probe
  • Display keypad is directly accessible without opening the cover
  • Measuring range up to 40 m / 131 ft
  • Converter backwards compatible with all flange systems of current (OPTIFLEX 1300 C) and previous (BM 100 A, BM 102) generation TDR meters from KROHNE
  • SIL2-compliant according to IEC 61508 for safety-related systems
