Direct Mode-Mounting Frames, Spacer Bar And Spacing Guides - Siemens SITRANS FUH1010PVDX Operating Instructions Manual

Section 3
Put mounting strap around transducer and tighten as in Step 5. Sight along spacer bar to ensure axial
alignment to the pipe. Adjust if necessary and do not overtighten. Ensure that the transducers do not
move while tightening.
7. Connect the transducer cable, ensuring that you have observed the upstream/downstream orienta-
tion in respect to the cable and the input jack on the flow computer. If this is a dual-channel unit, make
sure you are connecting the cables to the correct channel's input jacks. Repeat this procedure for the
number index transducer.
8. Return to the menu, and press <ENT> to finish the transducer install routine.
3.3.8 DIRECT MODE - MOUNTING FRAMES, SPACER BAR AND SPACING GUIDES
The combination of mounting frames, spacer bar and spacing guides is the recommended way to mount
Direct Mode transducers. The mounting frame establishes the axial alignment of the transducers, and
allows you to remove and replace either transducer while preserving their exact mounting location.

INSTALLATION - DIRECT MODE WITH TRANSDUCERS, MOUNTING FRAMES,
For Direct Mode mounting, you will use a spacer bar to establish the distance between transducers and
a spacing guide to easily locate the transducers at the nine o'clock and three o'clock positions. Should the
distance between transducers be beyond the span of a spacer bar, a measuring tape can be used. The
Mylar spacing guide comes in various lengths and widths to accommodate most pipe sizes (see list
below).
