Figure 16 below shows an odd traverse installation without
the transducers. Proceed to the section on mounting the
transducers later in this chapter.

2.7 Transducer installation
For any of the fixtures above except for the SPCF, the last
step in the installation is mounting the transducers into the
clamping fixture. Although not all transducer models are
installed the same way, the following information provides
some general guidelines to help you. The face of the
transducer must be in contact with the pipe because this
is where the ultrasonic signal is emitted. All Panametrics
transducers include a dimple, depression as it is illustrated
in Figure 22, drill point or slot on the opposite side of the
transducer wedge face, for use as a guide in aligning and
securing the transducer. In addition, some transducers have
scribe marks on the side to assist in setting the transducer
spacing. Figure 17 below shows an example of the dimple
and scribe marks on the transducers.
Figure 17: Transducer samples
To mount the transducers into a clamping fixture, complete
the following steps:
1. To ensure that the minimum bend radius of the cable
is met, the cable adapter is added in series with
the transducer cable assembly and the transducer.
Connect the transducer cables to the BNC connectors
on the transducers, ensuring that the labels on the
cables match with the transducers. For example, the
cable labeled ‘downstream’ must be connected to the
downstream transducer.
