Magnetic Level Gauge

Magnetic level gauge consists of a float, carrying a set of strong permanent magnets, riding in an external tube (Float Chamber) attached to the vessel by two nozzles.

As the float moves up and down along with liquid level, a magnetized shuttle or bar graph indication moves with it, indicating the position of the float and thus providing the level indication.

Auxiliary column and chamber walls are made of non-magnetic material, mostly exotic materials like Hastelloy C-276 or engineered plastics.

Advantages

  1. Float designs can be optimized for the specific gravity of the fluid being measured, whether butane, propane, oil, acid, water, or interfaces between two fluids, as well as a large selection of float materials.
  2. They can handle high temperatures, high pressures, and corrosive fluids.
  3. Oversized float chambers and high-buoyancy floats are available for applications where buildup is anticipated.
  4. Steam jacketing can be used for Liquid Asphalt.
  5. Oversizes chambers can be used for Flashing conditions.
  6. Cryogenic temperature designs can be used for liquid nitrogen and refrigerants.
  7. Titanium, Incoloy, and Monel are available for varying combinations of high-temperature, high-pressure, low-specific-gravity, and corrosive-fluid applications.
