5. Once transducer is in place, secure with the transducer clamping screw. Do not overtighten. Ob-
serve the upstream/downstream orientation and connect the transducer cable to the computer’s
input jack. If a dual-channel unit, make sure you connect the cable to the input jacks of the correct
channel. Repeat this procedure for the number index transducer.
Installing a 1012T Mounting Track in Direct Mode
Paragraph 2.4 describes the Transducer Installation procedures that lead up to the automatic selection
of transducers, mounting mode and spacing method. Shown is a Model 1012T mounting track to
accommodate size B3 universal transducers. Examine the figure below which shows a typical Pick/
Install Xdcr menu screen. Note the automatic assignment of model numbers for the transducer and
mounting track, plus the designation of number index.
1. Perform all required menu steps up until the point where the flow computer prompts you to press
to finish the transducer install routine. Note the reported number index.
You will be inserting an index pin into this hole and the reference hole. 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. The direct mount configuration uses two track rails, one for each transducer, installed 180
0
apart on
the pipe. One track rail includes the tension screw while the other has a locating stud to support the
chain (see below and on next page).
