Section 3
1. Perform all the required menu steps up until the point where the flow computer issues the number
index and prompts you to press <ENT> to finish the transducer install routine.
Make a note of the number index displayed in the Pick/Install menu. Check to ensure that you have a
matched set of transducers. They both should have the same S/N number but marked with either an “A”
or “B” (e.g., 100A and 100B).
2. Temporarily position one of the frames on the pipe where you will be mounting it. Ensure that this is
a smooth area without any raised areas (seams, etc.) With a pencil or chalk, mark a generous area
around the frame (1/2” on either side and half again the length front and back). Remove the assem-
bly.
3. Prepare the area you marked by de-greasing surface, if needed, and removing any grit, corrosion,
rust, loose paint or surface irregularities with the abrasive material provided.
4. Put a mounting strap around the pipe and engage an end into adjusting screw (screw should be
pointing up). Position frame in the middle of area you have cleaned and centered on the pipe with its
angled end facing away from where the other frame will sit.
WRAPPING STRAP UNDER PIPE AND ATTACHING TO ADJUSTING SCREW
5. Slide the mounting strap over it (and under the clip if there is one) and tighten with a screwdriver.
While tightening, check to ensure that the center of the tapered roller is centered on the pipe.
6. Attach the second frame to the spacer bar with an index spacer screw into the index hole specified
in Step 1. The angle on the frame should be facing away from the direction the length of the bar is
going. Now attach the free end of the spacer bar by inserting an index spacer screw through the REF
hole on the spacer bar and then into the hole on the mounted frame. Tighten. Sight to ensure that this
frame is lined up in center of pipe and while holding alignment, place a dot (with pencil or chalk) in
the center of the tapered roller at the bottom of the frame (see A below). While holding, also mark
along the front edge of the frame with pencil or fine chalk line (see B below).
