Important Safety Information!
CAUTION:
(Standard version) Never remove the flow sensor
from a pressurized pipe. Always wear safety face
protection during sensor installation/removal.
(Hot-Tap version) Follow the recommended
installation/removal instructions in this manual.
Always wear safety face protection during sensor
installation/removal.
Pipe fittings MUST be installed by a certified
welder only. OMEGA will not assume liability of
any kind for improper fitting installations.
Serious bodily injury and/or damage to the sensor
can result if the conditions and specifications
presented in this manual are exceeded. DO NOT
exceed specifications under any circumstances.
The FP-6000 Hot-Tap system's overall specifica-
tions and limitations depend on the lowest maxi-
mum rating of the components associated with the
system. In other words, the Hot-Tap system is only
as strong as its weakest link. For example, a ball
valve, a component of the system, is rated at a
maximum 100 psi @ 185 °F, limiting the entire
system's maximum pressure/temperature rating to
100 psi @ 185 °F. All higher maximum specifica-
tions MUST yield to the component with the lowest
maximum specification.
Maximum Operating Pressure:
225 psi (15 bar)
Maximum Operating Temperature:
212 °F (100 °C)

assistance, please contact your OMEGA dealer.
1.1 Description
The FP-6000 Series is an insertion flow sensor
used to measure the flow velocity of fluids through
process pipes. The sensor insertion depth is
adjustable, allowing installation into metal pipes
ranging from 11/2 to 24 inches in diameter (11/2
to 36 in. for Hot-Tap). The Hot-Tap version
enables installation in active pipes, reducing
downtime to a minimum. Wetted parts include
C36000 brass, CD4MCu steel, tungsten steel,
Fluoroloy B, and Viton®.
The FP-6000 Series mounts on the pipe through
any standard 11/2 inch female pipe fitting. The
unit comes equipped with standard NPT threads
or optional ISO 7/1-R 11/2 threads.
1.2 Theory of Operation
Liquid flowing through a process pipe rotates the
sensor paddlewheel. An AC frequency is induced
into the sensor coil which is proportional to the
fluid velocity in amplitude and frequency. The AC
signal is then input to a control instrument where
the frequency is converted to engineering units and
used to display flow rate and control external
devices.
Fluid
Flow
Patented open-cell rotor
design provides a linear AC
output over a wider velocity
range.
1
The linearity and accuracy of the FP-6000 Series
sensor depend on predictable flow conditions in
the pipe and proper location of the fitting. As
with any insertion flow sensor, the pipe must be full
and generally free of air pockets.
Chapter 2
Installation and
Wiring
2.1 Location of Fitting
The sensor must be located in a free-flowing
straight run of pipe. OMEGA recommends a
minimum of 10 pipe diameters of straight pipe
upstream and a minimum of 5 diameters down-
stream to insure a fully developed flow profile.
Any obstructions to the flow will require consider-
ably longer straight runs. Figure 1 illustrates
several common situations and recommended
piping distances.

2.2 Sensor Position
When installing the sensor in a horizontal pipe run
the optimum position is at 0° or 180°, assuming
the line is always full and contains no solids.
Air pockets or sediment in the line will disturb the
rotation of the paddlewheel, causing inaccuracy in
the calibration. Installing the sensor at an angle
2
(max. 30°) will help to avoid these problem areas,
but use caution. Excessive angles will cause
bearing drag at lower flow rates.
On a vertical pipe run locate the sensor where the
flow is upward. If downward flow is necessary
the system must be designed to prevent air/water
vapor pockets from developing in the pipe which
will affect the performance of the sensor.

Special Considerations
For Hot-Tap installations allow at least 3 feet of
vertical clearance for sensor installation plus the
distance required for the isolation valve and fittings
attached to the pipe. More clearance may be
necessary to suit the drilling machine used during
sensor installation.

3.5 Calculating the H Dimension
For Hot-Tap installations, we
assume pipe dimensions are
known
Before installing the sensor some critical dimen-
sions must be established. The rotor shaft must be
located 10% inside the pipe I.D. to insure accurate
calibration capability. To accomplish this, the "H"
dimension is measured from the outside surface of
the pipe to the bottom of the sensor flange.
Nominal "H" dimensions for standard pipes are
listed on page 18-19. For irregular pipe dimen-
sions, calculate the "H" dimension using the given
formulas (page 7). The 6 inch ruler may be used
to measure the I.D. and wall thickness of pipes up
to 5 inch (standard sensors only).

Using the Hot-Tap Installation Tool
The Hot-Tap installation tool helps to lower the
sensor into place against the pressure in the pipe.
1. Thread protector plate hex nuts onto each of the
three threaded rods. Adjust each hex to a height
of approximately 1 in. (25 mm) from the top of
each rod. Remove the black plastic cable grom-
met in top of sensor with a screwdriver. Slide the
grommet up the cable away from sensor.
2. Position the installation tool bearing plate by
rotating it so that it is approximately 2 inches away
from the swivel mount. Mount the installation tool
by placing the threaded rods through the holes in
the tool's bearing plate, resting the bearing plate
on top of the protector plate hex nuts. Make sure
the swivel mount's ears are mounted between the
threaded rods (not over the rods). Install the
bearing plate cap nuts. Tighten the bearing plate
cap nuts to secure the installation tool in place.

etc.) and open the bleed valve (ccw rotation) to
relieve internal pressure. Pull sensor up until bleed
valve purges some fluid (indicating sensor is past
1st o-ring seal inside brass sensor nut) then remove
sensor from brass sensor nut/threaded rod
assembly.
Caution: In case of a leaky isolation valve, the
sensor will be under a slight amount of pressure.
Care should be taken when removing the sensor.
Use the bleed valve to relieve this pressure taking
care not to spray fluid on yourself or others.

5.3 Rotor Replacement Procedure
Rotor Pin
1. With a small pair of needle-nose pliers, firmly
grip the center of the rotor pin (axle) and with a
twisting motion, bend the rotor pin into an "S"
shape. This should pull the ends of the pin out of
the shaft retainers and free the rotor assembly.
2. Remove shaft retainer from each side by gently
tapping it inwards using a punch. Install a new
shaft retainer with the rotor shaft clearance hole
inward. Only install one shaft retainer at this
time.

3. Insert the new rotor assembly and bearings into
the rotor housing of the sensor and place the new
rotor pin (axle) through the open end of the rotor
housing, through the rotor and bearings, and into
the previously installed shaft retainer.

K-factors and A-factors are listed in
U.S. gallons and in liters. Conversion
formulas for other engineering units
are listed below.
• The K-factor is the number of pulses generated
by the FP-6000 series paddlewheel per unit of
liquid in a specific pipe size.
K = 60/A
A = 60/K
• The A-factor is the flow rate (per minute) repre-
sented by 1 Hz output from the FP-6000 series
sensor in a specific pipe size.

Caution: The FP-6002 and FP-6003 Series Hot-
Tap system's overall specifications and limitations
depend on the lowest maximum rating of the
components associated with the system. For
example, a ball valve, a component of the system,
is rated at a maximum 100 psi @ 185°F, limiting
the entire system's maximum pressure/temperature
rating to 100 psi @ 185°F. All higher maximum
specifications MUST yield to the component with
the lowest maximum specification.
Note: Pressure/temperature specifications refer to
sensor performance in water. Certain chemical
limitations may apply. Chemical compatibility
should be verified before sensor installation.
