GENERAL INFORMATION

GENERAL INFORMATION

The FP6500 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 Omega.

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.

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 “hot-tap” models (FP6511/6512) 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.

The resulting square-wave signal can be sent for hundreds of

INSTALLATION

"D"

These ow sensors are not recommended for

installation downstream of the boiler feedwa-

ter pump where installation fault may expose
the meter to boiler pressure and temperature.
Maximum recommended temperature is

200ºF.

Piping. For best results, the FP6500 should be installed with
at least ten diameters of straight pipe upstream and ve down-

stream. Certain extreme situations such as partially-opened

valves are particularly difcult and may require fteen diameters

upstream (See Straight Pipe Recommendations).

Immersion. The FP6500-Series standard sensors are not

designed for continuous underwater operation.

Depth Setting. It is important for accuracy that the sensor be
inserted to the correct depth into the pipe.

1. In Table 1, nd Dimension C for your sensor model

and pipe size.

2. Subtract wall thickness of your pipe (Table 2) to

nd Dimension D.

Horizontal is the preferred installation orientation, since it im-

proves 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)

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.

INSTALLATION

FP6501/6502 INSTALLATION

(Add -SS for stainless)

Fitting Installation. FP6501/6502 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.

FP6511/6512 INSTALLATION

(Add -SS for stainless)

‘Hot tap’ FP6500 Series meters are designed to be installed and serviced

without depressurizing the pipe.

Fitting Installation. The 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 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, preceding page). Be sure ow is

in the direction of the arrow on the housing. Tighten locking collar and
compression nut fully.

CONNECTION

Sensors are supplied with 18 ft. of cable. See diagram for color
coding of connections.

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 provided 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 FP6500-Series

sensors in the same installation. Typically, most K-factor error
can be attributed to installation variables, such as depth setting

and tting conguration.

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.

OPERATION
Theory. In principle, an insertion ow sensor measures the veloc-

ity 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 partially-opened gate or buttery 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 prole” 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 Range. 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.

REPAIR

CAUTION! Never attempt to remove a

ow sensor when there is pressure in

the pipe. Loosen the compression nut
slowly to release any trapped pressure.

If uid sprays out when removing the

sensor, stop turning and depressurize the pipe. Failure
to do so could result in the sensor being thrown from
the pipe, resulting in damage or serious injury.

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, FP15827. 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.

REPAIR & PARTS

Signal

The ow sensor has only one moving part, the rotor. If this is

turning properly and there is no signal, the Hall-effect 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 (gray cable) and damage sensor.
