Metaval’s Magnetic Level Gauges offer a safe, clear, and reliable solution for continuous liquid level monitoring across a wide range of industrial applications. These gauges are specifically designed to replace traditional glass level gauges, eliminating the risk of glass breakage and direct chemical exposure. The Magnetic Level Gauge consists of a float chamber, magnetic float, and external visual indicator, providing high-clarity level indication without direct contact with the fluid.

The Magnetic Level Gauge works on magnetic coupling. As the liquid level in the vessel changes, the float inside the chamber rises or falls accordingly. This float contains permanent magnets, which interact with the external visual indicator (either rotating bicolour rollers or moving capsule shuttle), accurately displaying the liquid level without physical contact.
