Liquid Level Switches
D E S C R I P T I O N
Magnetrol® displacement type level switches offer the
industrial user a wide choice of alarm and control
configurations. Every unit utilizes a simple buoyancy
principle and is well suited for simple or complex
applications, such as foaming or surging liquids or
agitated fluids, and usually costs less than other types of
level switches.
F E A T U R E S
• Narrow or wide level ranges achieved through
multiple switch mechanism capability.
• Up to 4 set points and 3 switches.
• Displacers adjustable at any point along the
suspension cable.
• 10 feet (3 meters) suspension cable standard.
• Anti-surge design eliminates the possibility of switch
shortcycling.
• Flanged or threaded mounting available.
• Easy installation.

T E C H N O L O G Y
Operation is based upon simple buoyancy, whereby a
spring is loaded with weighted displacers which are
heavier than the liquid. Immersion of the displacers in
the liquid results in buoyancy force change, which
moves the spring upward.
Pivot

Since the spring moves only when the level moves on a
displacer, spring movement ¿ is always a small fraction
of the level travel between displacers ¡.
5
A magnetic sleeve ¬ is connected to the spring and
operates within a non-magnetic barrier tube √. Spring
movement causes the magnetic sleeve to attract a pivoted magnet ƒ, actuating a switch mechanism ≈ located
outside the barrier tube. Built-in limit stops prevent over
stroking of the spring, under level surge conditions.

The purpose of the PROOF-ER is to check the operation
of a displacer control without having to raise the level in
the tank. This is accomplished by pulling downward on
the PROOF-ER chain. A spring-loaded lever arm then lifts

The floating rooftop control is designed for installation on

condition. When the chain is released, the PROOF-ER
returns the actuator to its previous position to resume normal operation.
C O N T R O L S
A hollow brass displacer is required if the control is to
actuate in liquid as well as by the barrier. Consult factory
for other options.

LEVEL ALARM APPLICATIONS
NARROW DIFFERENTIAL TYPE
These wide differential units are factory calibrated to
actuate as a liquid level reaches a given displacer and
to deactuate when the level reaches a second
displacer.
These instruments are factory calibrated to operate over
a narrow level differential band and are ideally suited
for liquid level alarm applications on either high or
low level.
The minimum differential band is approximately 6 in.
(152 mm) in water and varies somewhat with liquid specific gravity. The maximum differential is determined by
the length of the displacer suspension cable.
The operating level is fully adjustable simply by
repositioning the displacer along its suspension cable.
The differential band varies slightly with liquid
specific gravity.

NARROW DIFFERENTIAL TYPE
These wide differential tandem units are factory calibrated
with a choice of several operating sequences designed to
meet virtually any application.
These instruments utilize two switches — each actuated
at a different level and each calibrated with a narrow
differential band.
OPERATING SEQUENCES
Model B10 units are available with a choice of switch
operating sequence. Five of the most popular
sequences are described on page 8. When ordering,
specify operating sequence number and specific gravity
of the liquid.

NARROW DIFFERENTIAL TYPE
These wide differential type switches are designed to
provide three electrically separate control signals in a
selected sequence as liquid level varies.
These instruments are factory-calibrated to operate over
a narrow level band while providing three electrically
separate control signals as liquid level varies.
These units come factory-calibrated with a choice
of several operating sequences combining wide and
narrow level differential.
