Required transducer separation 230mm or less:
1. Position the two guide rails horizontally on the pipe at 45° with respect to the top and bottom of the pipe and secure in position
using the supplied stainless steel banding (see Figure below).
2. Follow the instructions provided for Reflex Modes, fitting the downstream transducer in the lower guide rail and the down-
stream transducer in the top guide rail.

3. Position the upstream guide rail horizontally on the pipe at 45° with respect to the top of the pipe and secure it in position using
the supplied stainless steel banding.
4. Fit the upstream transducer into the guide rail but do not fasten it in position yet.
5. Position the downstream guide rail at the approximate location to give the required separation under the pipe. For example,
if the required separation is 450mm, align the guide rail so that the zero marks on the two guide rails are 400mm apart. The
remainder can then be accounted for by sliding the upstream transducer to the 50mm mark (see Figure above). This allows for
any fine adjustments that may be necessary during use.
6. Fit the downstream transducer so that the inner face is aligned with the zero mark on the
guide rail.
7. Adjust the position of the upstream transducer so that the overall separation distance is
correctly achieved.
8. Lower the two transducers onto the pipe by turning the transducer clamps anti-clockwise.
An easy way to draw a perpendicular circumference around a large pipe is to wrap a length of material such as a 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 over-
laps. Then, after removing the paper from the pipe, bold the measured length in half keeping the edges parallel. The fold line now
marks a distance exactly halfway around the pipe. Put the paper back on the pipe and use the fold line to Mark the opposite side of
the pipe.
