SAFETY INSTRUCTIONS
1. The FP-319 Flow Wet-Tap Valve may only be installed into, and removed from, non-pressurized
systems (0 psig).
2. The pressure must be reduced to 25 psi when removing or installing the sensor and must
maintain 25 psi or lower while the sensor is removed.
3. Stay clear of sensor stroke area and safety cable during sensor removal.
4. Confi rm chemical compatibility before use.
5. Do not exceed maximum temperature/pressure specifi cations.
6. Wear safety goggles or faceshield during installation/service.
7. Do not alter product construction.
Failure to follow safety precautions may result in severe personal injury!

2. Wet-Tap Valve Installation
The OMEGA FP-319 Flow Wet-Tap Assembly attaches directly to OMEGA installation fi ttings to enable fl ow sensor removal without
system shutdown. It consists of a fl ange and support plate which thread onto the pipe fi tting insert, and a PVC ball valve through which
an extended length fl ow sensor is inserted into the pipe.
Caution: The FP-319 Flow Wet-Tap Valve may only be installed into, and
removed from, non-pressurized systems (0 psig).
Procedure
1. Remove six hex nuts and bolts from the Wet-Tap fl ange. Separate the support plate
from the main assembly. Be sure that the Viton O-ring is properly seated in the
support plate groove.
2. Apply sealant to the pipe fi tting insert threads to prevent leaks.
3. Screw support plate onto pipe fi tting insert (O-ring side facing up). It must be
threaded completely down until the notches at the top of the pipe fi tting insert are
exposed.
4. Mount the main Wet-Tap Assembly on the support plate. Make certain the
alignment keys on the fl ange mate with the notches on the pipe fi tting insert.
5. Loosen support plate (holding the main Wet-Tap Assembly in place) until it resists
slightly. Loosen an additional 1/4-turn to seat O-ring.
6. Replace the six hex nuts and bolts to secure the Wet-Tap Assembly in place. Adjust
the support plate position as necessary to align screws.
7. Check the pressure relief plug on Wet-Tap Assembly. It must be closed fi nger tight
to prevent leaks.
8. Close ball valve by turning the handle to the fully closed position (parallel with pipe).

3. Flow Sensor Insertion/Removal
To insert the fl ow sensor:
1. Lubricate the sensor O-rings with a lubricant compatible
with your process and the sensor materials of construction.
Do not use petroleum based lubricants that will attack the
O-rings.
2. Carefully insert the sensor into the FP-319 valve assembly
until the fi rst two O-rings seat inside the bore (Figure 1).
• Do not damage the rotor on closed ball valve.
3. Using the clamps, attach the sensor safety cable to the
FP-319 assembly brackets (hand tighten only).
4. Pull the fl ow sensor upward to remove slack in the safety
cables (Figure 2).
WARNING: Safety cables are factory installed at
precise length. DO NOT attempt to service or replace
safety cables.
WARNING: System pressure must be 25 psi
or less prior to sensor insertion or removal.
5. Open the ball valve (Figure 2).
6. Push the fl ow sensor into the FP-319 assembly with a
twisting motion.
• Turn the sensor so the arrows on the black conduit cap
point in the direction of fl ow.
• When properly aligned the sensor bale will be parallel
with the pipe (Figure 3).

To remove the fl ow sensor:
WARNING: System pressure must be 25
psi or less prior to fl ow sensor insertion or
removal. Stay clear of sensor stroke area
and safety cable during sensor removal.
WARNING: Check the six (6) hex bolts (Figure 2)
prior to unscrewing the sensor cap. If bolts are loose,
tighten securely before proceeding.
1. Unscrew the sensor cap. DO NOT use any tools that may
damage plastic parts.
2. Carefully pull the fl ow sensor upward with a twisting motion
until the safety lanyards are fully extended (Figure 2).
3. Close the ball valve (Figure 1).
4. Loosen the relief plug to depressurize the sensor area.
5. Disconnect the sensor safety cable clamps from the FP-319
assembly brackets.
6. The sensor can now be safely removed.
