Magnetic Level Gauge

Sigma magnetic level gauges provide clear level indication across a wide range of operating conditions. They are maintenance free, guard against leakage and protect the environment, which makes them a safe choice for corrosive, toxic, flammable, explosive or polluting fluids and for liquids that look alike at an interface.

How it works

The gauge has a float chamber, a float and an external indicator. An engineered float carrying an internal magnet travels inside the chamber and follows the level in the vessel. As it moves, the magnet flips the indicator flags, which stay flipped until the float passes back the other way. Because the flags are magnetically coupled to the float, nothing leaks even if the indicator is struck.

Each float is engineered for the right buoyancy in its application, based on the specific gravity, pressure and temperature of the process fluid, and every material of construction is chosen to suit that fluid.
