138 K55 for Aggressive Liquids

K55 is designed for use in continuous level detection of aggressive liquid preferably for corrosive media, acidic applications with moderate fumes. It has range of 10m and is available in a plastic sealed antenna for protection from aggressive media.
  • No moving parts: High Reliability, Maintenance Free.
  • Graphical display.
  • High sensitivity for detection of weak echoes from turbulent surfaces.
  • False echo storage function to select only true echoes for accurate level measurement.
  • Antenna material suitable for corrosive media.
  • Dual chamber construction helps isolation of electronics from gland terminals.
  • Narrow beam angle, Max. Measuring range up to 10 m.
  • Conventional 4-20 mA or HART output options.
  • Level to Volume conversion through HARTMATE configuration software (With 64 points conversion table)
