MLG Magnetic Level Gauges

Magna-Site^TM MAGNETIC LEVEL GAUGE

Operating Principle

The KENCO Magna-Site^TM is a magnetic liquid level indicator used to determine
the volume of liquid contained within a vessel. Because the Magna-Site^TM 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^TM utilizes three 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 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° magnetic-flux field. Each float is internally
weighted based on 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^TM. The assembly
is made up a 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° magnetic flux of the float. This magnetic interaction
causes each flag to rotate 180°. The flags below the magnetic flux of the float will
flip to fluorescent green, while those flags above the float level remain steel gray.

GAUGE FEATURES:

Maximum safety -- No glass is used in the construction.

Optimum visibility -- Fluorescent flags are visible from great distances

Float with 360° magnetic flux -- Maintains a strong magnetic field in all
directions; turbulent liquids will not cause flag assembly to give an inaccurate
level indication.

Double flag protection -- Flags are hermetically sealed inside a PTFE encapsulated
assembly which is shrouded by a 300 series stainless steel enclosure on three
sides with a UV stabilized high-impact clear polycarbonate shield

Adjustable viewing angles -- Flag assembly can be rotated to any angle to provide
maximum visibility.

Multiple mounting options -- Design allows for a variety of mounting configurations

Compatibility -- A broad range of materials can be used to withstand harsh chemicals

Remote level indication -- Explosion-proof magnetostrictive level sensor/transmitter
provides a 4-20mA signal output

Height scale -- 304 stainless steel with no. 3 finish and large etchedcharacters/lines
for easy reading

High/Low level switches -- Explosion proof switches can signal an alarm, operate a
pump/valve or act as an emergency shut down

Convenience -- Easy installation and very low maintenance

Warranty -- Three year guarantee against defects
