GENERAL INFORMATION

IP800-SERIES INSTRUCTIONS

The IP800-Series are impeller (or “paddlewheel”) insertion
meters designed for use with a wide variety of liquids
in pipe sizes 1/2" to 8". Sensors are available in brass,
316 stainless steel, PVC, and polypropylene. Bodies are
machined from a solid rod for maximum precision. High­quality jewel bearings and nickel-bound tungsten carbide
shafts are used for extreme low friction and long life. Low-

ow performance is good, although other Seametrics ow
meters are recommended where extremely low ows are

being measured.

The rotation of the rotor is detected by a non-drag Hall­effect sensor. Output is a current-sinking pulse, which
can be sent long distances (up to 2,000 feet) without a
transmitter. This signal can be connected directly to PLC's,
counters, and computer cards, as well as a variety of
Seametrics controls and displays.

Seametrics IP meters are ideal for chemical proportioning
applications. If no display is required, a simple divider such
as the PD10 provides adjustable pump pacing. For rate

Features

and total display, a modular system of electronics can be

installed directly on the ow sensor or mounted remotely.

The FT430 (externally powered with pulse), FT440 (loop
powered), and FT450 (battery powered) all provide digital
rate and total displays, as well as a programmable pulse;
the FT440 also provides a 4-20 mA analog output. The
AO55 blind analog transmitter can be used to convert to a
4-20 mA output. Electronic modules can be wall- or meter­mounted. (Note: PD10 available only as wall mounted unit.)
IP meters are also compatible with the DL76 data logger
and FT520 batch processor.

The IP800-Series require special ttings that ensure correct

depth placement in the pipe. Fittings come in a variety

of materials for compatibility with specic applications.
Tee ttings are individually wet-calibrated at the factory

and marked with the K-factor (pulses per gallon). Saddle

ttings must be eld-installed on the pipe and do not

come wet-calibrated. K-factors for saddles are based on
factory-testing.

INSTALLATION

IP800-SERIES INSTRUCTIONS

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 prole 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 specic adverse circumstances

(see next page).

If you can’t provide enough straight run to smooth out

the velocity prole, 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.

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.

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).

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.

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

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.

under pressure may result in damage or serious injury.

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
