The IP100/200-Series are adjustable depth insertion
paddlewheels that come in brass, PVC, or 316 stainless
models to t 3” to 40” pipe. Adapters mate with standard
1-1/2” (11x/21x) or 2” (15x/25x), or PVC (11x/21x) NPT
threaded ttings such as saddles and weldolets which may
be purchased either locally or from Seametrics.
Ruby bearings and a non-drag Hall-effect sensor give these
meters the widest ow range of any of the paddlewheel
types. A sensor detects the passage of miniature magnets
in the six rotor blades. The resulting square-wave signal
can be sent for hundreds of feet over unshielded cable
without a transmitter and connected directly to many PLC’s
and other controls without any additional electronics.
Features
Housing Screw
(connect one to ground)
Optional Electronics Module
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 is a
blind analog (4-20 mA) transmitter. Programmable pulse
for pump pacing is available with the PD10 (available as
wall mounted unit only).
The “hot-tap” models (IP15x/25x) can be installed or
serviced without shutting down the line by means of a
2” full-port isolation valve that comes with a nipple for
installation on the pipe tting. In most circumstances, no
special tool is required.

INSTALLATION
IP100/200 SERIES INSTRUCTIONS
Positioning the Meter
For best results, the IP sensor should be installed with
at least ten diameters of straight pipe upstream and
ve downstream. Certain extreme situations such as
partially-opened valves are particularly difcult and may
require fteen diameters upstream. (See Straight Pipe
Recommendations.)

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.
Immersion
The IP100/200 Series standard sensors are not designed
for continuous underwater operation. If this is a possibility,
as in a ooded vault, a unit modied for immersion should
be specied (Option -40).
Caution: These ow sensors are
not recommended for installation
downstream of a boiler feedwater
pump where installation fault may
expose the ow sensor to boiler pressure
and temperature. Maximum recommended
temperature is 200°F.

INSTALLATION
IP11x/21x Installation
Fitting Installation. IP11x/21x brass/SS adapters mate with a
1-1/2” female NPT pipe thread adapter tting (2" for PVC). Any
tting that provides the matching NPT female thread may be used.
Installation procedure compensates for tting height differences.
Cut a minimum 1-3/4” hole in the pipe. If possible, measure the wall
thickness and write it down for use in depth setting. Then install the
threaded tting (saddle, weldolet, etc.) on the pipe.
Meter Installation. Loosen the compression nut so that the adapter
slides freely. Pull the meter fully upward and nger-tighten the
compression nut. Using a thread sealant, install the adapter in the
pipe tting. Do not overtighten. Now loosen the compression
nut, lower the meter to the appropriate depth setting (see diagram
and instructions that follow). Caution: Do not allow the meter to fall into the pipe uncontrolled, as this may damage the meter.
Be sure ow is in the direction of the arrow on the housing. Fully
tighten compression nut.

Hot tap’ IP meters are designed to be installed and serviced without
depressurizing the pipe.
Fitting Installation. The IP15x and 25x adapters mate with a 2”
FNPT threaded tting for compatibility with the 2” isolation valve.
Any tting that provides matching NPT female thread may be used.
The installation procedure compensates for differences in tting
height.
If initial installation is performed on an unpressurized pipe, cut a
minimum 1-3/4” hole in the pipe. If possible, measure the wall
thickness and write it down for use in depth setting. Then install the
threaded tting (saddle, weldolet, etc.) on the pipe.
If it is necessary to do the initial installation under pressure, any
standard hot tap drilling machine with 2” NPT adapter, such as a
Transmate or a Mueller, can be used. Ordinarily, it is not necessary
to use an installation tool, since the small-diameter tube can be
controlled by hand at all but the highest pressures.
Meter Installation. Remove the sensor unit from the valve assembly.
Using a thread sealant, install the valve assembly on the pipe tting.
If the initial installation is a pressure (“hot”) tap, remove the 1-1/2”
x 2” adapter bushing at the back of the valve. Thread the tapping
machine on, open the valve, and tap using a minimum of 1-3/4” or
maximum 1-7/8” cutter. After retracting the machine and closing
the valve, reinstall the ow sensor. When the sensor is secure, open
the valve and adjust depth setting (see diagram and instructions that
follow). Be sure ow is in the direction of the arrow on the housing.

OPERATION AND MAINTANENCE
IP100/200 SERIES INSTRUCTIONS
Operation Theory
In principle, an insertion ow sensor measures the velocity
of ow at one point in the pipe, and ow rate and total
can be inferred from this one point. Accuracy is decreased
by any factor which makes the ow at the measured point
unrepresentative of the entire ow stream. This includes
distorted ow patterns caused by upstream ttings too
close to the sensor. The worst offenders are ttings that
increase the ow on one side of the pipe, such as partiallyopened gate or buttery valves. Fluid moving in a pipe
does not all ow at the same velocity. Toward the center
of the pipe, uid moves faster than at the wall, and the
relationship between the two changes as overall ow rate
increases. This change in the “velocity prole” can result
in non-linearity, which means that the K-factor that is
correct for one ow rate may be incorrect for another. The
recommended depth settings have been carefully chosen
to minimize this source of error, and should be followed
carefully, especially in the smaller pipe sizes.
Flow Rate
These sensors are designed to operate at ow velocities
of 0.3 to 30 feet per second. (See chart for conversion to
gallons per minute.) If erratic readings are encountered at
low ows, check the chart to see if ow is below minimum
for the pipe size. The standard shaft and bearings should
have a long life at continuous high ow.
All Seametrics ow sensors are repairable, and can be
returned to the factory or distributor for repair after a
Return Material Authorization (RMA) number has been
issued.
Rotor Replacement
Rotors are easily eld-replaced. Shaft and rotor are a single
unit, and are not replaced separately. If replacement is due
only to normal shaft wear, bearing replacement is probably
not necessary. If the rotor has been damaged by impact,
the bearings should also be replaced. Rotor and bearings
can be ordered as a kit, Part No. 25902. Follow these steps:
1. Unscrew the threaded bearing housings to expose
the shaft ends. If bearings are being replaced, back
them completely out.
2. Remove the rotor. Put the new rotor in its place.
3. Thread in one bearing housing part way, then the
other. Take care to start the end of the shaft into
the bearing hole before tightening further.
4. Screw in bearing housings until they bottom.
Note: Do not use excessive force.
5. Check for free spin. Blowing lightly on the rotor
should result in it spinning rapidly and coasting to a
smooth stop.
Calibration (“K-Factor”)
In order to properly process pulses from the ow sensor,
a number must be entered into the control to which the
sensor is connected. This number, called the K-factor, is
the number of pulses the sensor puts out per unit of
uid passing through the pipe. It is normally provided
for Seametrics sensors in pulses per gallon, and is given
on the chart “K-factors for Various Pipe Sizes.” These
numbers are based on extensive testing, which has shown
close agreement between different IP sensors in the same
installation. Typically, most K-factor error can be attributed
to installation variables, such as depth setting and tting
conguration.
It is occasionally possible to eld calibrate a sensor by
catching the uid in a measured container and comparing
with the number of pulses recorded. (To record individual
pulses, set the K-factor on the control to 1.00.) This is
especially desirable if the installation has less than the
recommended length of straight pipe upstream of the
sensor.
Checking Signal
The ow sensor has only one moving part, the rotor. If
this is turning properly and there is no signal, the Halleffect sensor is not operating properly. To check the signal,
apply 12 Vdc regulated* power to the red (+) and black
(-) leads. Set a multimeter to voltage reading. Put the
positive multimeter lead on the red wire and the negative
lead on the white wire. Slowly turn the rotor. Voltage
reading should swing between +12 Volts and 0 Volts as
the rotor turns. If it does not, the Hall effect sensor is not
working properly. Checking for continuity is not a useful
test of these sensors.
*NOTE: An unregulated power supply can exceed max
voltage of micro-powered sensor pickup (gray cable) and
damage sensor.
