Features

  • Wide selection range for temperature and pressure.
  • Variety of material selection for displacer, spring and chambers for suitable anticorrosive capability.
  • Perfect isolation between pressurized part and electric compartment by magnetic coupling for high reliability and safety.
  • In addition to watertight construction, pressure tight and intrinsically safe versions are ready to meet hazardous application.
    Especially, pressure tight flameproof suitable for Hydrogen atmospher (Ex dIIC T6) is available which eliminates the necessity of safety barriers.

 

Applications

  • Fuel oil tank level control
  • Process control for petrochemical plants
  • Water treatment plants
  • Other liquid level control
