3. After setting up parameters,the UFM displays the axial
distance between the ultrasonic transducers (trans-
ducer distance) is displayed. Measure the transducer
distance based on the value displayed on the UFM,
starting from the first line drawn to the position at which
the second line is to be drawn (mounting position for
face of the second transducer).

4. Draw two cross hairs on the same axis, centered on
the lines drawn with the help of the template.

5. Mount the first transducer. Its face is positioned on the
axis of the first line drawn. The
transducer face
(not
the transducer) is centered onto the first cross hair.
Now calculate half of the pipe’s outer circumference.
