Magnetic level indicator

Magnetic level indicators show the liquid level in tanks or boilers reliably and without contact. They are preferred in systems with aggressive chemicals and at high temperatures and pressures.

Operation

  • A float inside the chamber moves up and down with the liquid level.
  • Strong magnets in the float actuate the indicator elements on the outside of the tube.
  • The indicator usually consists of transparent or coloured flaps (flippers); as the magnetic float passes, they turn and the colour change shows the level.
  • Some models can be fitted with level switches and an analogue-output transmitter.

Advantages

  • Contact-free indication: the float works inside the chamber while the indicator is outside, keeping the process sealed.
  • High durability: materials resistant to pressure and corrosion (e.g. stainless steel, PP, PVDF).
  • Long service life: the mechanical design works for years with little attention.
  • Easy to read: the level is clearly visible even from a distance.

Applications

  • Chemical industry: level of acid, alkali and solvent tanks
  • Power plants: boiler and condensate tank monitoring
  • Food & beverage: control in liquid production lines
  • Water treatment: storage and reactor tank monitoring
  • Petrochemicals: oil and fuel tank level monitoring

Considerations

  • The float material must suit the density and chemistry of the liquid.
  • As it works magnetically, nearby electromagnetic equipment can affect its accuracy.
  • On tall tanks visual reading can be difficult; models with an output are recommended there.
