Buoyancy Level Controls
A Time-Tested Solution
Vertical Float
he application of buoyancy principles to the
challenges of liquid level measurement and control
is one of the oldest and most reliable solutions available
in the process control industry. The key to the success
of buoyancy instruments is the means by which the
motion of the liquid and, therefore, the float or
displacer is converted into the desired level control
action. Magnetrol® incorporates the optimal features
into its level switches while providing repeatable,
dependable performance. The result of completely
isolating the process environment from the switching
mechanism and keeping all magnetic components out
of the process environment, is a robust, versatile instrument suitable for a wide variety of control applications.
The float orientation utilized for top mounted
switches and as the primary sensing method for external cage switches is the vertical float. The principle of
operation is simple and provides a practical solution to
narrow level differential requirements.
A rigid stem and attraction sleeve assembly is
affixed to the top of a spherical or oblong float. The
size of the float determines the buoyancy force of the
process liquid against the float, stem and sleeve assembly. This buoyancy force must be greater than the
weight of the assembly and is increased by enlarging
the float. Because the buoyancy force is greater, the
float assembly rises directly with the liquid level. As it
does so, the attraction sleeve moves within a static
pressure boundary, the enclosing tube. A permanent
magnet is attached to the switch assembly outside of
the enclosing tube. When the attraction sleeve enters
the field of the switch magnet, the magnet is pulled
toward the sleeve, snapping against the enclosing tube
and causing the switch to change state. As the liquid
level falls, the float/stem/sleeve assembly follows it.
When the attraction sleeve moves out of the field of the
switch magnet, a return spring on the switch mechanism pulls the magnet away from the enclosing tube,
returning the switch to its original state.

Displacer Switches
While taking advantage of the same buoyancy and
unit, operates much like a vertical float. It utilizes the
same components, float, stem, sleeve, enclosing tube,
magnetic coupling principles as float switches, displacer
level switches utilize a precision range spring to con-
slightly different manner. The lower float stem pivots
vert the change in buoyancy force to movement of an
attraction sleeve. Because the displacer is weighted,
on a fulcrum. This means that as the float rises, the
it hangs into the liquid rather than floating on top. As
attraction sleeve is pulled down out of the field of the
the liquid level moves changing the volume of liquid
switch magnet causing the magnet to be pulled away
displaced by the displacers, the buoyancy force on the
from the enclosing tube. Conversely, as the float falls,
displacers changes. This causes elongation or compres-
the sleeve moves upward causing the switch magnet to
sion of the range spring which, in turn, moves the
pull in. Side mounted controls may be used for wide
attraction sleeve into or out of the field of the switch
magnet, changing the state of the switch.
switch magnet and mechanism, but functions in a
level differential. By lengthening the float stem, the
liquid level and float must move through a greater distance in order to change the state of the switch. Side
mounted units offer the option of mounting toward
the bottom of a vessel for use in low level service,
something that may not be done with a top mounted
vertical float.
