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 crosshair. Now, calculate half of the pipe's
outer circumference..

r = Radius of pipe including wall thickness („outer radius“)
Example: Radius (outer) = 250mm -> U = 2*3.1415*250mm / 2 = 785.4mm

Position the zero line of the measuring tape onto the center of the
second crosshair drawn on the pipe (at same level as first
transducer). Measure the previously calculated distance (half
circumference). You should now have located the precise position
opposite to the first transducer. Draw a (third) onto the pip at this
position.

Mount the second transducer. Its face is positioned on the axis of
the second line drawn. The
transducer face
is centered onto the
third crosshair. The transducers are now mounted precisely
opposite to each other and are prepared for measuring in Z-mode.
