The Babbitt LG-Series magnetic level gauge consists
of a float chamber, a float, and an external indication device.
The float chamber is basically a column of 2 1/2 inch pipe with
process connections to match those of the storage tank, reactor,
drum, column or other equipment where level is to be measured. These
connections may be side couplings or flanges, or top and bottom
flanges. The float moves up and down inside the chamber as
the process level changes. The float type is determined by the
process fluid specific gravity, pressure and temperature. Also,
the materials of construction must be compatible with the process
fluid. The float must be light enough to maintain buoyancy and
have properties that allow it to withstand the pressure and temperature
combination. The each float is engineered for proper buoyancy
for each particular application for level or interface measurement.
Contained
inside the sealed float is a very strong magnet assembly. The indicator
tube and scale assembly is attached to the outside of the float
chamber. Inside the transparent, hermetically-sealed indicator tube
is a light-weight magnetized indicator. This indicator is magnetically
coupled with to the float and moves up and down inside the indicator
tube as the float moves up and down with the rising and falling
of the liquid level in the vessel. The indicator is brightly colored
and allows the operator to read the level from 100 feet away. The
only moving parts are the float and the indicator. An optional Flipper/Roller
style indicator is also offered.
The basic Babbitt
magnetic level gauge offers simple visual indication. By using the LT1 transmitter, a 4-20mA
signal can be sent to a remote location for indication or control
functions. Additionally, level switches can be added, external to the float chamber, for alarm or control.
These switches can easily be moved up or down the chamber while
not disturbing the process. |
