Magnetic float level gauge involves the use of a permanent magnet sealed inside a float whose rise and fall causes a change in the color of its external indicator. For both magnetic and mechanical float level sensors, chemical compatibility, temperature, specific gravity (density), buoyancy, and viscosity affect the selection of the stem and the float. Larger floats may be used with liquids with specific gravities as low as 0.5 while still maintaining buoyancy. The choice of float material is also influenced by temperature-induced changes in specific gravity and viscosity – changes that directly affect buoyancy.
The chief benefit of using an MLG is isolation from process liquid. Separation allows for easy access to the level gauge for cleaning and eliminates contact with difficult media.
