A Magnetic Level Indicator (MLI) is a reliable visual level measurement device used to indicate the liquid level inside tanks or vessels. It works based on buoyancy and magnetism—a float moves up and down with the liquid level inside a chamber, and magnets inside the float rotate the external indicator flaps to display the level accurately. Since it is non-invasive, the process fluid never touches the indicator.

Magnetic Level Gauges are widely used in:

chemical storage tanks
separators and pressure vessels
oil & gas process tanks
water and utility tanks
LPG / fuel tanks (based on suitability)
pharmaceutical and industrial liquid containers
They are best suited wherever continuous visual level monitoring is required.
