Magnetic Level Gauge

Sigma's Magnetic Level Gauge's operation is based on elementary principles of physics: Liquid attains the same level in communicating vessels, Unlike magnetic poles attract and like poles repel, Last but not the least, Archimedes principle. Sigma Magnetic level gauge consists of a vertical chamber consisting of a non magnetic tube of suitable diameter and thickness, float, where-in magnets are placed radially exactly on the liquid level line (floating point), Two horizontal stub pipes with specified end connection, An indicator outside the vertical chamber comprising of a set of flags that contain a set of permanent magnet encapsulated, which can rotate on their horizontal axis or a magnetic follower that moves along in a transparent tube, Optional shut off valves at the two stub pipes to isolate the level gauge, A non magnetic scale with graduations in mm/cm/inches. As the float moves up and down with changing level, the following action takes place:In case of the flag type, the flag indicator consists of bicolored flags that are contrasting dark and bright colors. The bright represents the liquid level and the dark color depicts the empty or interface fluid level. The float immerses only on the upper fluid and floats on the lower for which the specific gravity suitability is maintained. In case of the follower type, the indicator consists of a encapsulated magnetic follower that follows the rise and fall of the magnetic float.
