INSTALLATION PROCEDURES FOR THE MAGNA-SITE
(THE MAGNETIC LEVEL GAUGE FROM KENCO)
OPERATING PRINCIPLE
The Kenco Magna-Site is a magnetic liquid level gauge used to determine
the volume of liquid within a vessel. Because the Magna-Site eliminates
the need for glass, high-pressure applications and hazardous locations are
protected from the danger of a chemical spill due to glass failure.
The Kenco Magna-Site utilizes 3 major components: the gauge housing
chamber, the magnetic float, and the magnetic flag assembly.
The Gauge Housing Chamber is mounted adjacent to the side of the tank
vessel. It is constructed to withstand the same temperatures and
pressures as the tank itself. It is equipped with the appropriate tank
mounting connections for easy installation and to allow equalization of
liquid level in tank and gauge.
Inside the Gauge Housing Chamber is the magnetic float, which contains
radially positioned magnets to provide a 360 degree magnetic flux field.
Each float is internally weighted based on the liquid’s specific gravity so
that the liquid level in the gauge coincides with the location of the magnets
inside the float.
Attached to the Gauge Housing Chamber is the magnetic flag assembly.
This is the visual means of liquid level indication for the Kenco Magna-Site.
The assembly is made up of a series of bi-colored fluorescent flags. As the
magnetic float rises and falls with the liquid level in the gauge housing
chamber, a magnet embedded in each flag reacts to the 360 degree
magnetic flux of the float. This repelling magnetic force causes each flag
to rotate 180 degrees. The flags below the magnetic flux of the float will flip
to fluorescent green, while those flags above the float level will remain
white.
