Section 3
3.6.5 USING 1012T MOUNTING TRACKS
The 1012TP Mounting Tracks provide a rigid mounting platform for Series 1011 Universal transducers.
The mounting tracks service pipe sizes up to a maximum of 5.00" (140 mm) outer diameter. The
assembly consists of lightweight aluminum track rails with integral transducer clamping screws. At-
tached index pins enable positive locating of the transducers at fixed spacing locations. Roller-chains
and tension screws secure the assembly to the pipe. The following instructions refer to 1011 Universal
transducers.
The 1012T mounting tracks support both Direct and Reflect mounting modes. The flow computer
recommends the appropriate transducers, mounting track and mounting mode, based on the pipe
data entries. Refer to the instructions in paragraph 3.5 for details on the Transducer Installation proce-
dure. If necessary, review paragraphs 3.2.2 through 3.3.5 for details on how to select and prepare a
mounting location on your pipe.
Installing a 1012T Mounting Track in Reflect Mode
Paragraph 3.6 describes the Transducer Installation procedures that lead up to the automatic selec-
tion of transducers, mounting mode and spacing method. 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 (see below), plus the designation of the number index.
Transducer Model
> 1011 Universal
This example requires a Model 1012T Mounting Track to accommodate size B3 Universal transduc-
ers. Note the reported number index. You will be inserting an index pin into this hole on the track rail to
position one of the transducers (see diagram on next page).
1. Perform all required menu steps up until the point where you respond to the [Install Complete?]
prompt. Note the reported number index. You will be inserting index pins into this hole and the
reference hole on the track rail (see diagram on next page). 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).
