5. Apply a 1/8-inch continuous bead of couplant compound along the center (the long way) of
the contact surface of the transducer. Position this transducer on the center of the pipe in
the middle of area you have cleaned; the cable connector facing away from where the other
transducer will go.
6. While holding the transducer in-place, bring the chain around the pipe and attach the clos-
est cross-link onto the hook of the EZ clamp. Tighten the adjusting nut until the chain is
just snug around the pipe. Check to ensure that the chain is straight around the pipe and
that the transducer is contacting the pipe at the white dot just under the front label. En-
sure also that there is equal space on either side of the dot between the edges of the trans-
ducer and the pipe. Adjust if necessary. Tighten the chain but do not overtighten. Ensure
the transducer did not move while tightening.
7. Attach the second transducer to the spacer bar at the index hole specified in paragraph #1.
Note that in some cases, the transducers may have two sets of holes for securing the spacer
bar. When using the EZ clamp assembly, use the lower set of holes when attaching the
spacer bar.
8. Unlike the first transducer, do not apply any couplant at this point. Attach the spacer bar
(with the second transducer attached to it) to the mounted transducer by inserting an in-
dex screw through the REF hole in the bar and into the lowest hole on the transducer.
Tighten. Visually ensure that the spacer bar is axially aligned with the pipe. While holding
in this position, pencil a line (or a fine line with chalk) along the back edge of the trans-
ducer and a dot below where the white dot is below the front label (see “A” below). Disas-
semble the spacer bar and second transducer from the mounted transducer and remove the
transducer from the bar. Use the bar as a straight edge and, with one edge against the
mounted transducer’s white dot and the other crossing the dot you drew, draw a line cross-
ing the dot (see “B” below). Set the bar aside.
