Section 3
5. Once transducer is in place, secure with the transducer clamping screw. Do not overtighten.
Observe 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 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 trans-
ducer 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 <ENT> 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).
