Figure 7. Orientation of Flow Arrow

• Once the sensor is completely bottomed, slide the

retaining ring over the three retaining studs and

tighten the retaining nuts until the ring presses

firmly against the weld ring. (This will prevent the

sensor tip from vibrating free from the opposite wall

of the pipe). Jam nuts should now be threaded on

and pressed tightly against the retaining nuts.

Warning: The retaining ring must be secured

before the come-along is removed.

• At this point, the come-along can be safely

removed.

• Re-verify that the orientation of the sensor is such

that the arrow labeled “flow” on the instrument

head is in the direction of the flow in the pipe to

within 3° (Figure 7).

Warning: The retaining ring should not be removed

unless a come-along is properly attached and all

slack is removed from the come-along.

The Verabar is now properly installed (Figure 8).

Periodic Maintenance

The assembly should be periodically checked. Verify

that no leaks are present. Tighten the packing bolts if

necessary.

Sensor Removal Procedure

• Shut off instrument valves.

• Properly install a come-along and remove all slack

from the come-along.

• Remove jam nuts and retaining nuts.

• Pull retaining ring off retaining studs.

• Slowly retract the come-along and do not allow

more than 1/2” (13mm) of slack to develop in the

come-along during the entire retraction process. It

may be necessary to assist the sensor removal by

pulling on the instrument head.

• Retract the sensor until the safety cable is tight.

• Completely shut off the access valve. Slowly

crack open one of the Verabar instrument valves

and bleed off any remaining pressure contained in

the access nipple. The sensor assembly can now

be removed.
