PUMP OR VALVE CONTROL
WIDE 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.
The minimum differential band is approximately 6 in.
(152 mm) in water and varies somewhat with liquid spe-
cific gravity. The maximum differential is determined by
the length of the displacer suspension cable.
SERIES A15
LEVEL ALARM APPLICATIONS
NARROW DIFFERENTIAL TYPE
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 operating level is fully adjustable simply by
repositioning the displacer along its suspension cable.
The differential band varies slightly with liquid
specific gravity.

WIDE DIFFERENTIAL TYPE
These wide differential tandem units are factory calibrated
with a choice of several operating sequences designed to
meet virtually any application.
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.
SERIES B15
NARROW DIFFERENTIAL TYPE
These instruments utilize two switches — each actuated
at a different level and each calibrated with a narrow
differential band.

WIDE 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 units come factory-calibrated with a choice
of several operating sequences combining wide and
narrow level differential.
SERIES C15
NARROW DIFFERENTIAL TYPE
These instruments are factory-calibrated to operate over
a narrow level band while providing three electrically
separate control signals as liquid level varies.
