OMEGA FP-2540/FP-3-1500
SAFETY INSTRUCTIONS
1. Do not remove from pressurized lines.
2. Do not exceed maximum temperature/pressure specifications.
3. Wear safety goggles or faceshield during installation/service.
4. Do not alter product construction.
5. Apply sealant or PTFE tape to sensor threads, inspecting threads to ensure integrity.
Do not install a sensor with damaged threads.
Pipe fittings MUST be installed by a certified welder only. Omega will not assume liability of any kind for improper fitting
installations.
Omega FP-3-1500 Series Hot-Tap sensor specifications and limitations depend on the lowest maximum rating of the
components associated with the system. If a ball valve, a component of the system, is rated at a maximum 100 psi @ 175 °F,
the entire system's maximum pressure/temperature rating is limited to 100 psi @ 175 °F. All higher maximum specifications
MUST yield to the component with the lowest maximum specification.
Maximum Operating Pressure/Temperature:
• 17 bar (250 psi) @ 100 °C (212 °F) with standard FPM sensor fitting O-rings.
• 17 bar (250 psi) @ 82 °C (180 °F) with optional EPDM sensor fitting O-rings.
Note: Pressure/temperature specifications refer to sensor performance in water. Certain chemical limitations may apply.
Chemical compatibility should be verified.

The electronics module of this sensor can be replaced without removing
the steel sensor body from the line.
1. Loosen liquid tight connector cap.
2. Loosen liquid tight connector compression fitting from sensor body.
3. Grasp the electronics at the rubber strain relief (do not pull on cable)
and pull firmly.
To reinstall the electronics module:
• Insert module into sensor housing, making sure module is fully seated.
Electronic pick-up module tip must bottom-out in the sensor housing.
• Replace the liquid tight connector assembly.

Chemical Compatibility Warning
The retaining nuts of paddlewheel sensors, pH and ORP sensors as well as Magmeters are not designed for prolonged
contact with aggressive substances. Strong acids, caustic substances and solvents or their vapor may lead to failure of the
retaining nut, ejection of the sensor and loss of the process fluid with possibly serious consequences, such as damage to
equipment and serious personal injury. Retaining nuts that may have been in contact with such substances e.g. due to leakage or
spilling, must be replaced.

The following items are required to properly install Omega FP-2541/FP-3-1500 Sensors.
5.1 Hardware, Standard Sensor
•
•
•
•
Female pipe fitting (weld-on or saddle) with 1.5 in. NPT threads
32 mm (1.25 in.) diameter drill

5.4 Hot-Tap Fitting Installation
A. Install the pipe fitting on the outside diameter of the pipe according to the manufacturer's instructions. Failure to follow these
instructions may result in serious bodily injury and/or product failure.
B. Install the pipe nipple and isolation valve (ball or gate valve) onto the external pipe fitting using pipe sealant on the threads. (Fig. 2)
C. Wearing safety face protection, install an appropriate hole cutting tool per manufacturer's instructions (e.g., Mueller
drilling machine) with a 32 mm (1.25 in.) drill onto the top of the isolation valve, ensuring a tight fit. Use the
recommended drill bit size or damage to the isolation valve may occur.
D. Open the isolation valve and insert the drill through the valve and cut the sensor clearance hole. After the hole is cut, withdraw the
drill from the isolation valve and close the valve. Remove the drilling machine per manufacturer's instructions. (Fig. 3)
E. Install the sensor fitting/bleed valve into the top of the isolation valve. Make sure the bleed valve clears the handle of the isolation
valve during operation.

5.5 Calculating the H Dimension

Before installing the sensor some critical dimensions must be
established. The rotor shaft must be located 10% inside the pipe
I.D. to ensure 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.
"H" dimensions for standard pipes are listed below.
For non-standard pipe dimensions, calculate the "H" dimension
using the formula below, based on the pipe's wall thickness and
inside diameter (id).
Use the 6 inch ruler to
measure the pipe id and
wall thickness up to 5
inches (standard sensors
only). (For Hot-Tap
installations, the pipe
dimensions are assumed
to be known.)

A. Thread one hex nut onto each of the three threaded rods
included in package. Install threaded rod with a lock washer
onto the sensor fitting. Secure rods in place by tightening each
hex nut against the sensor fitting. (Fig. 4)
B. Thread one jam nut and lower hex nut onto each threaded
rod so that the top surface of each nut is at the proper "H"
dimension for your pipe. Secure each hex nut with a jam nut.
(Fig. 5)
C. Insert the flow sensor into the sensor fitting, making sure the
alignment hole on the sensor flange is pointing downstream.
D. Place the alignment rod in the alignment hole on the sensor
flange. Align the flange so rod is parallel to the process pipe.

Place the slotted flange over the threaded rods. Lower the
sensor into the fitting until the sensor flange rests on the lower
hex and jam nuts.
D. Secure the sensor with lock washers and upper hex nuts on
the top of the flange. Before tightening, align the sensor flange
so that the alignment rod is parallel and level with the process

F. Thread protector plate hex nuts onto each of the three threaded
rods. Adjust each hex nut to a height of approximately 25 mm

grommet in top of sensor with a screwdriver. Slide the grommet
up the cable away from sensor. (Fig. 10)

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. (Fig. 11)
H. Align the sensor cable with the swivel mount cable port to
prevent cable pinching. Use a 3/8 inch wrench or socket to turn
the installation tool shaft clockwise until it is seated in the hole at
the top of the sensor flange.

with suitable protection (rag, towel, 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 sensor fitting).
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.

Sensor can now be safely removed. When reinstalling the sensor: Leave one lower hex nut in position to guide sensor to proper
isolation valve clearance height before opening isolation valve. Return to "H" dimension height after valve is opened.

Fluid Conditions
Maximum operating pressure/temperature:
• Sensor with standard FPM sensor fitting O-rings:
17 bar (250 psi) @ 100 °C (212 °F)
• Sensor with optional EPR sensor fitting O-rings:
17 bar (250 psi) @ 82 °C (180 °F)
NOTE: Pressure/temperature specifications refer to sensor
performance in water. Certain chemical limitations may apply.
Chemical compatibility should be verified.
CAUTION: The OMEGA FP-3-1500 Hot-Tap system's
overall specifications and limitations depend on the
lowest maximum 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
@ 175 °F, limiting the entire system's maximum pressure/
temperature rating to 100 psi @ 175 °F. All higher maximum
specifications MUST yield to the component with the lowest
maximum specification.
