Mounting
the
EchoSwitch®
The
sensor
should
always
be
mounted
perpendicular
to
the
liquid
surface
using
the
provided
Viton®
mounting
gasket.
Make
sure
that
there
are
no
restrictions
or
obstacles
in
the
path
of
the
acoustic
signal.
For
further
mounting
information,
please
refer
to
the
EchoPod®
manual
and
instruction
video
located
at
www.flowline.com.
EchoSwitch®
has
1”
NPT
or
G
threads
and
requires
care
in
fitting
selection
and
mounting
to
reduce
any
coupling
of
the
ultrasonic
signal
to
the
mounting
structure.
The
below
fittings
are
recommended.
Installation
in
existing
2”
fittings:
1)
Use
a
LM52
‐
1400
2”
thread
x
1”
thread
adapter
or
a
LM52
‐
1410
2”
slip
x
1”
thread
adapter.
Adapters
with
an
air
gap
around
the
1
inch
threads
are
recommended.
Installation
in
plastic
tanks
(use
one
of
the
following)
:
1)
Use
a
1”
bulkhead
fitting,
such
as
the
LM52
‐
1890
bulkhead
fitting.
2)
Use
a
larger
bulkhead
fitting,
such
as
the
LM52
‐
2890
with
a
reducer
bushing
such
as
the
LM52
‐
1400.
3)
Weld
a
plastic
1”
half
coupling
to
the
tank
top.
Installation
in
metal
tanks
(use
one
of
the
following):
1)
Use
the
LM52
‐
1890
bulkhead
fittings.
2)
Use
a
flange
with
a
1”
riser,
such
as
the
LM52
‐
1850
(where
the
thread
is
above
the
plane
of
the
flange).
Do
not
use
a
blind
flange
with
a
tapped
1”
thread.
3)
Use
a
larger
flange
with
a
2”
thread
and
add
a
reducer
bushing
such
as
the
LM52
‐
1400.
Note:
While
installations
directly
into
a
1”metal
fitting
are
not
recommended,
acceptable
results
may
be
obtained
if
the
1”
fitting
is
a
half
coupling
in
form
and
the
outer
diameter
of
the
coupler
is
tightly
wrapped
with
vinyl
tape.
Installation
in
open
tanks
and
sumps:
1)
Use
Flowline's
