of the tool over the positioning collar and secure by
tightening the two thumbscrews on the top of the yoke.
7. Close the bleed petcock and slowly open the isolation
valve. Slowly turn the 15/16 inch drive nut clockwise to
insert the sensor tube assembly through the valve and
into the pipeline. Carefully guide the three threaded studs
of the hex mounting adapter through the holes of the
sensor positioning collar. Carefully lower the sensor until
the positioning collar contacts the hex nut preset for the
correct depth adjustment. Install the three lock nuts onto
the threaded rods, tightening only the lock nut on the
threaded rod with the preset hex/jam nut; then, bring the
two remaining lock nuts down until they just contact the
positioning collar. Do not tighten at this time
8. Remove the Model HTT Insertion/Removal Tool, by
loosening the two thumbscrews, removing the clevis pin
and then sliding the insertion tool off the sensor. Then
bring the two remaining sets of hex/jam nuts up to the
underside of the positioning collar, and tighten.
9. Align the sensor by first loosening the two set screws in
the side of positioning collar with a 3/32 inch Allen wrench.
Then align the sensor sight holes along the pipe axis
using the alignment rod provided in the sensor installation
kit. Ensure that the flow label arrow on the sensor
matches the liquid flow direction inside the pipe. Tighten
the positioning collar set screws. Note: As a backup to the
flow label arrow, there is a small hole located beside the
sight hole on the upstream side of the sensor.
