Meter Installation
After the meter tting is installed in the pipeline, the
meter can be installed in the tting. Press the meter into
the tting as far as it will go. Retain the meter in place by
inserting the U-clip. The clip can be installed from either
side. It may be necessary to rotate the probe back and
forth slightly to start the clip into the slots on the probe.
Slide the clip in as far as it will go.
Horizontal (3 o’clock or 9 o’clock position) is the preferred
installation orientation, since it improves low-ow
performance and avoids problems with trapped air and
sediment. (See Orienting the Meter diagram below.)
Bottom (6 o’clock), top (12 o’clock), and vertical pipe
installations are all acceptable if required by the piping
layout.
Orienting the Meter
Caution: These ow sensors are not
recommended for installation downstream
of the boiler feedwater pump where
installation fault may expose the ow
sensor to boiler pressure and temperature.
Maximum recommended temperature is
130°F (Plastic), 200°F (Metal).

Caution: Never remove the U-clip retainer
when the pipe is under pressure. Always
remove pressure from the pipe before you
attempt to remove the meter. Removal
under pressure may result in damage or serious injury.
INSTALLATION
Fitting Installation
The IP800-Series are xed-depth meters that must be used
with matched ttings appropriate to the application and
pipe size. This ensures that the ow sensor is installed at
the correct insertion depth to measure the average ow
velocity of the stream.
Straight pipe of at least 10 diameters upstream and
ve diameters downstream of the meter is strongly
recommended for proper accuracy. This is necessary
because the shape of the velocity prole changes as the
rate increases around an elbow; placing the meter too near
the elbow causes a distorted reading. Additional straight
run may be needed under specic adverse circumstances
(see next page).
If you can’t provide enough straight run to smooth out
the velocity prole, some decrease in accuracy may result.
This does not mean the meter’s reading is meaningless,
however. In some applications (e.g., control system, valve
operation) a repeatable reading may be more important
than a highly accurate one.
Distorted Flows
Stainless steel and brass ttings have female pipe threads,
requiring the appropriate male threaded ttings. Saddle
ttings require a hole to be cut in the pipe (recommended
hole size is 1-3/4”). Before cutting into the pipe, observe
the drawing below to choose your meter orientation.
A PVC tting is usually installed by solvent welding. PVC
tees are supplied with some upstream straight pipe, less
than the recommended straight pipe requirements. It is not
advisable to connect directly to the end of these ttings
with a ow disturbing device (valve, elbow), but rather
add straight pipe to the end of these ttings to meet the
straight pipe requirements for your application.
