The spacing should now appear similar to that in Figure 1-20 below.

1.4.5.4 Installing the
Transducers
1. Check to be sure the second CFG-PI holder bracket is correctly positioned.
2. Apply a bead of CPL-16 couplant 6 mm (0.25 in.) wide on each transducer face
(see Figure 1-21 below).

Note: Do not slide the transducer with couplant along the surface of the pipe when
mounting the transducer.
3. With one hand, mount one transducer into the PI fixture. With the other hand,
tighten the thumbscrew, gradually pushing the transducer down to the pipe
surface. Use a wrench to tighten the backing nut to prevent loosening due to
vibration and thermal expansion.
IMPORTANT: Do not use pliers or a wrench on the thumbscrew.
4. Repeat step 3 for the other transducer.
