INSTALLATION - REFLECT MOUNT WITH TRANSDUCERS AND SPACING BAR

1.Perform all required menu steps until the flow computer issues the number index and prompts you to press ENT to finish the transducer install routine. Stop at this point.

Note the number index value displayed in the Pick/Install menu. You will use this index to properly space the transducers. 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.Assemble the transducers to the spacer bar, with the cable connectors facing away from each other as shown above. The spacer bar is attached to a transducer using a transducer index screw. One transducer is attached using the “REF” hole on the spacer bar. The second transducer is attached to the spacer at the index hole specified in Step 1.

3.Temporarily position the assembly (in the 9 o’clock position) at the location where you have determined it would be mounted. Ensure that it is a smooth area without any raised spots or seams. Mark a generous area around the transducers (1/2” on either side and half again the length front and back) with a pencil or chalk. Remove the assembly.

4.Prepare the two areas 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 all debris and abrasive particles.

5.Remove transducer from the spacer bar that was attached through the REF hole. Put a mounting strap around the pipe and engage an end into the adjusting screw (adjusting screw should be pointing up). Apply a 1/8-inch continuous bead of couplant compound down the center (the long way) of the contact surface of one of the transducers (see Recommended Sonic Coupling Com- pounds Section 5, page 5-9). Place the transducer on the pipe center in the middle of one of the areas you have cleaned with its cable connector pointing away from the other cleaned area. Holding the transducer in place, 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 white dot under the front label is centered on the pipe and that there is equal space on both edges. Also, make sure to position strap for easy access to the mounting strap adjusting screw.

6.Repeat Step 5 with the second transducer leaving it still attached to the spacer bar. Apply a 1/8-inch bead of couplant to the transducer. At the same time you place it in the middle of the second area prepared, secure the spacing bar to the already mounted transducer by inserting the transducer index screw through the REF hole on the Bar. Put mounting strap around transducer and tighten as
