GENERAL INFORMATION
GENERAL INFORMATION
The IPFS Series are adjustable depth insertion paddlewheels
that come in brass or 316 stainless models to t 3” to 40” pipe.
Installation ttings are standard 1-1/2" or 2” NPT. Fittings such
as saddles and weldolets may be purchased either locally or from
Dwyer Instruments Inc.
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.
If desired, a modular system of electronics can be installed

directly on the ow sensor or mounted remotely. The Series RTI
provides digital rate and total display, as well as programmable
pulse output; the Series RTI also provides a 4 to 20 mA analog
output. The Series BAT is a blind analog transmitter. Programmable pulse for pump pacing is available with the Series PWD.
The “hot-tap” models IPFS-1 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.
Modular electronics (optional)
• rate/total/pulse/4-20 mA
• blind 4-20 transmitter
• pulse divider

INSTALLATION
INSTALLATION
These ow sensors are not recommended
for installation downstream of the boiler
feedwater pump where installation fault
may expose the meter to boiler pressure
and temperature. Maximum recom-
mended temperature is 200˚ F.
Piping. For best results, the IPFS 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 is the preferred installation orientation, since it
improves low-ow performance slightly and avoids problems
with trapped air. Bottom, top, and vertical pipe installations
are all acceptable if required by the piping layout. (See Full
Pipe Recommendations.)
POSITIONING THE METER
Fair (unacceptable if
air is present)
Immersion. The IPFS 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 -IMM)
Depth Setting. It is important for accuracy that the sensor be
inserted to the correct depth into the pipe.
1. In Table 1 (on page 4), nd Dimension C for your sensor model
and pipe size.
2. Subtract wall thickness of your pipe (Table 2 on page 4) to
nd Dimension D.
3. Measuring from the outside of the pipe to the joint in
the housing, as shown in the diagram, adjust the sensor
to Dimension D and hand tighten compression nut.
4. Align the conduit housing with the centerline of the pipe,
as shown below. Be sure the arrow on the housing
points in the direction of ow.

5. Check Dimension D one more time.
IPFS-0XX INSTALLATION
Fitting Installation. IPFS-0XX sensors come with a 1-1/2” male NPT pipe
thread adapter tting. 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, preceding page).
Caution: Do not allow the meter to fall into the pipe uncontrolled, as
this may damag the meter. Be sure ow is in the direction of the arrow
on the housing. Tighten compression nut fully.
IPFS-1XX INSTALLATION
‘Hot tap’ meters are designed to be installed and serviced without
depressurizing the pipe.
Fitting Installation. The hot tap sensors have a 2” NPT thread 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 but not
for higher pressures.

RECORD YOUR SETTINGS
Once you have the meter set up and operational, it is important to record your meter setttings and save them for
future reference.

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, preceding page). Be sure ow is
in the direction of the arrow on the housing. Tighten locking collar and
compression nut fully.
