Installing the Transducers

1. Apply a bead of couplant 6 mm (0.25 in.) wide along the

entire length of each transducer face, as shown in Figure 3-10

below.

Figure 3-10: Couplant on Transducer Face

Note: Do not slide the transducer with couplant along the

surface of the pipe when mounting the transducer.

2. Set the first mounting block (either left edge or right edge) at a

convenient number on the scale, such as 1 in. or 1 cm. Install

the first transducer with the BNC connector pointing away

from the center of the V block fixture. Tighten the transducer

mounting thumbscrew onto the slider, which in turn applies

pressure to the transducer. Use a handtight grip to set the

transducer in contact with the pipe, as shown in Figure 3-11

below. Use a wrench to tighten the backing nut to prevent

loosening due to vibration and thermal expansion.

IMPORTANT: Do not use a wrench or pliers on the

thumbscrew.
