Step 3: Install the Transducers.
A. Apply a thin bead of CC128 to the bottom side of the
transducers along their center length. See Fig 3-1.
B. Visually confirm the presence of insulating tape on the inside
walls of the enclosure. Insert the Fixed Transducer into the
Enclosure at the Reference location. Don’t land the
transducer on the pipe at this time. Install the cable. See Fig 3-2
through 3-4. Fill connector with CC110 grease prior to
connection. Backfill the protective boot and slide into place.
(Note: Be careful not to catch or compromise the insulating
tape while inserting the transducer.) .
C. Land the transducer onto pipe. Butt the front face of the
transducer against the center support. See Fig 3-5. Secure the
spacing strap as shown in Fig 3-6. Lift up on spring clip to install.
(Note that on some assemblies, the spacing strap will be fixed
to the center support. In this case the Reference transducer is
adjustable and the spacing strap is used to space both the
reference and the moveable transducers. See Fig 3-A) (Note: If
this is a Clamp-on Gas application using size C1 or D1
transducers, use “ALT” hole to position the Reference
Transducer. See Fig 3-B)
(Note: For direct mode, each enclosure will have one transducer from
each opposing set. {I.E. The enclosure at path 1 will have, mounted in
the Up-stream location, the “A” transducer from set “1” and mounted
in the Down-stream location will be transducer “B” from set “2”. The
enclosure at Path 2 will have, mounted in the Up-stream location, the
“A” transducer from set “2” and mounted in the Down-stream location
will be transducer “B” from set “1”})
