Veris Verabar V110 Installation Instructions - Manual (Page 3)

5.2 Weld Threadolets to Pipe
•
Loosely assemble the sensor, compression nut,
back ferrule, front ferrule and compression body to
the threadolet (hand tight) and insert the sensor
assembly into the pipe.
•
Using the appropriate weld gap (1/16” [1.5mm]
typical), tack weld the threadolet into position
(Figure 3). Assemble the support plug into the
threadolet (hand tight) and tack weld the opposite
end threadolet into position, using the tip of the
sensor for alignment.
Figure 3. Weld Gap
•
Remove the sensor and opposite end support plug,
protect threads on the threadolets and finish
welding the threadolets to the pipe per applicable
piping codes.
5.3 Insert Sensor
•
Using appropriate pipe thread sealant, install
(completely tighten) the compression body into the
threadolet.
•
Slide the compression nut, back ferrule, then front
ferrule, onto the sensor cover tube. The back
ferrule and front ferrule must be in the proper
sequence and orientation as shown in Figure
2. The back ferrule must be next to the
compression nut with the tapered end pointing
toward the front ferrule. The tapered end of the
front ferrule must point towards the compression
body.
•
Slide the sensor, with compression nut and
ferrules attached, into the compression body (do
not tighten).
•
Align the head of the sensor so that the arrow
labeled “flow” on the head is in the direction of the
flow in the pipe to within 3° (Figure 4). Maintain
the head in this position for the remainder of the
operations.
•
Slide the sensor into the pipe until “Y” dimension
(as shown in Figure 5) is per the following table:
Sensor Size “Y” Dimension
V110-05 4.00" (100mm)
V110-10 5.50” (140mm)
•
While maintaining the “Y” dimension, tighten the
compression nut 1-1/4 turns past hand tight.
Verify the alignment of the sensor such that the
arrow labeled “flow” on the head is in the direction
of the flow in the pipe to within 3° (Figure 4). A
crescent wrench or pipe wrench can be applied to
the head of the sensor to make alignment
adjustments.
•
Install (completely tighten) the support plug into
the opposite end threadolet. Use appropriate pipe
thread sealant. The tip of the sensor should
protrude into the bore of the support plug.
