IMPORTANT
MOUNTING
GUIDELINES:
1)
Never
mount
the
sensor
at
an
angle.
2)
Liquid
should
never
enter
the
dead
band.
3)
Mount
at
least
3”
from
the
side
wall.
4)
Never
mount
in
a
vacuum.
5)
Do
not
obstruct
the
sensor’s
beam
width.
Mounting
with
a
Stand
‐
Pipe
:
A
stand
‐
pipe
may
be
used
to
dampen
turbulence,
separate
surface
foam
from
the
point
of
measurement
or
increase
performance
in
heavy
vapor.
When
mounting
the
sensor
in
a
stand
‐
pipe,
the
minimum
diameter
of
the
pipe
is
2”.
Larger
diameter
pipes
can
be
used.
The
pipe
should
be
attached
with
a
coupling
or
tank
adapter
and
reducer
bushing.
Avoid
the
use
of
multiple
pipe
fittings
when
possible.
An
ideal
mount
would
be
to
select
a
2”
coupling
(S
x
T
or
S
x
S)
and
connect
the
pipe
to
the
inside
slip
and
use
a
reducer
bushing
to
attach
the
sensor
(see
example
below).
The
pipe
length
should
run
the
measurement
span
and
the
bottom
of
the
pipe
should
remain
submerged
at
all
times
to
prevent
foam
from
entering
the
pipe.
Cut
the
bottom
end
of
the
pipe
at
45°
and
drill
a
1/4”pressure
equalization
hole
high
in
the
dead
band.
The
pumps
should
not
drive
liquid
past
the
open
end
of
the
standpipe
which
causes
the
liquid
in
the
pipe
to
oscillate.
