3.1.8USING 1012T MOUNTING TRACKS

The 1012TP and 1012THP Mounting Tracks provide a rigid mounting platform for Series 1011 universal or high precision size A or B transducers. The mounting tracks service pipe sizes up to a maximum of 5.00” (140 mm) outer diameter. Operating temperatures are supported up to 250°F (121°C). The assembly consists of lightweight aluminum track rails with integral transducer clamping screws. Attached 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. Please refer to Engineering Drawing 1012TP-7 for reflect mounting of high precision transducers and 1012THP-7 for direct mounting of high precision 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 2.4 for details on the Transducer Installation proce- dure. If necessary, review paragraphs 3.1.2 through 3.1.4 for details on how to select and prepare a mounting location on your pipe.

Installing a 1012T Mounting Track in Reflect Mode

Paragraph 2.4 describes the Transducer Installation procedures that lead up to the automatic selection 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 transducer and mounting track, plus the designation of the number index.

Note selection of mounting track part number and number index.

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 Completed?] 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).
