Periodic Maintenance

The assembly should be periodically checked. Verify

that no leaks are present. The jam nuts and packing

bolts should be tight.

Sensor Removal Procedure

• Shut off instrument valves.

• Reduce flow rate to below the maximum insertion

withdrawn DP/flow limit stated on the Verabar tag.

• Loosen jam nuts.

• Using the drive nuts, retract the sensor until the

stop nuts and jam nuts are pressing against the

threaded bushings. The drive nuts should be

alternately loosened approximately 1/8” (3mm) at a

time. This will prevent excess bowing of the cover

tube and drive rods.

• 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.
