17. Realign left edge of the guide with the sensor edge mark. Line up both vertical edges of
the guide and, ensuring that it is snug around the pipe, mark along the overlapping edge.
18. Remove Mylar spacing guide and lay it out on a flat surface. Either measure the exact
distance half-way between the overlap edge and the mark at the overlap, or fold the
guide from the overlap edge to the overlap mark and draw a line at the fold (halfway
point).

19. Reinstall the spacing guide; its left edge abutting the sensor's edge mark on the pipe and
the overlapping edge in line with the dot (now a line) on the pipe (see "C above). Tape it
in this position on the pipe. Take the second frame and place it against the edge of the
guide with its tapered roller centered on the center mark on the guide.
20. Temporarily position the sensor (in the 3 o’clock position opposite the mounted sensor -
see below) where it will be mounted. Ensure that this is a smooth area without any raised
spots (seams, etc.). With a pencil or chalk, mark a generous area around all sides of the
mounting frames. Remove the frame and the Mylar guide.

21. Prepare the area you marked by de-greasing the surface, if needed, and removing any
grit, corrosion, rust, loose paint or surface irregularities with the abrasive pipe
conditioning material provided. Clean the pipe of any debris and abrasive particles.
22. Replace the Mylar spacer guide back in the same position it was in and retape it to the
pipe.
