Calculating the transducer
position and drawing it on
paper

3. Construction of the sensor
The transducer position is calculated using the roll of paper supplied with the mounting kit.
Drawing paper
Step 1
The following pipe dimensions must be known before calculating the transducer position and
making the drawing.
1. Circumference (C)
2. Wall thickness (t)
The circumference is determined using the measuring tape. Make sure that the pipe's surface is
plane and free of dirt etc. The measuring tape must fit snugly around the pipe. Read the
circumference (C). Repeat the measurement several times to avoid inaccuracies.
The wall thickness is obtained by measuring a similar pipe whose wall thickness is accessible, or
by consulting the relevant standard.
Step 2
Draw a line x-x through the middle of the paper.
The line x-x should be at right angles to the edge of the paper.
