Special features

  • Simple, robust and solid design, long service life
  • Bypass chamber and float from stainless steel 1.4571, 1.4404 or special materials 
  • Pressure- and gas-tight separation between measuring and display chamber
  • The functioning of the magnetic display is guaranteed even in the event of power failures
  • Continuous detection of levels, independent of physical and chemical changes of the media such as: Foaming, conductivity, dielectric, pressure, vacuum, temperature, vapours, condensation, bubble formation, boiling effects

Design and operating principle

  • In a communicating bypass chamber mounted to the side of a vessel a float moves with the level of the medium to be measured.
  • The magnetic field of the radial-symmetric magnetic system positioned in the float activates the magnetic display attached to the outside of the bypass chamber as well as the switching and measuring elements.

Magnetic bypass chamber can easily be extended with electrical level accessories to provide an electronic output signal in addition to the visual display:

  • BGU - Magnetic Level Switch
  • BLR - Reed Level transmitter
  • BLM - Magnetostrictive level Transmitter

Application areas

  • Water separator and water supply in Electrolysers
