Endress+Hauser Liquipoint FTW32 Conductive Point level detection

The Liquipoint FTW32 offers simple and safe point level detection in conductive liquids. It offers numerous measuring possibilities due to multipoint detection (up to 5 rods).

  • Cost-effective probe for conductive liquids with detection of up to five point levels with one probe
  • No calibration required
  • Standard setting for the most common conductive liquids
  • No moving parts in the tank – long service life, reliable operation with no wear or blockages

For use in conductive liquids (as of 10μS/cm). For overfill prevention, dry running protection, two-point control of pumps or multiple point detection.
