A Side Mounted Magnetic Level Indicator (MLI) is a highly reliable and maintenance-free level measurement device designed for continuous visual monitoring of liquid levels in tanks, vessels, reactors, boilers, and storage systems. It operates on the principle of magnetic coupling, where a float containing a permanent magnet moves within a chamber according to the liquid level. This movement is transmitted magnetically to an external indicator, providing accurate and clear level indication without direct contact between the process fluid and the display system.
Side Mounted Magnetic Level Indicators are widely used in industries such as oil & gas, petrochemicals, chemicals, pharmaceuticals, power generation, food processing, and water treatment. Their rugged construction and ability to operate under high-pressure, high-temperature, and corrosive conditions make them an ideal choice for demanding industrial applications.
The indicator provides a continuous visual display of liquid level through a magnetic flap or roller assembly that changes color as the float moves, ensuring easy level monitoring from a safe distance.
