Fixing transducers in diagonal mode

For this mode of operation, fix the guide rails on opposite sides of the pipe. For horizontal pipes, the guide rails must still be fitted
on a 45° axis with respect to the top of the pipe. Mark a reference line around the pipe approximately where the upstream trans-
ducer is to be fitted and use this to measure out the required separation distance
Separation
NOTICE
An easy way to draw a perpendicular circumference around a large pipe is to wrap a length of material such as chart paper around
the pipe, aligning the edges of the paper precisely at the overlap. With the edge of the chart paper being parallel, either edge
describes a circumference around the pipe that is perpendicular to the pipe axis.Mark the chart paper exactly where it overlaps.
Then, after removing the paper from the pipe, fold the measured length in half keeping the edges parallel.The fold line now marks
a distance exactly half way around the pipe. put the paper back on the pipe and use the fold line to mark the opposite side of the
pipe.
