6.4.7 THE Ltn MENU CELL
This view only menu cell shows the distance in inches or millimeters between the front faces of the
transducers along the axis of the pipe. If you are mounting the transducers without a track or spacer
bar, you have to space them according to this value. Note that Ltn may be a negative number for direct
mount on very small pipes where the transducer spacing overlaps.
6.4.8 HOW TO USE [INSTALL COMPLETE?]
Use the [Install Complete?] menu cell to inform the flow computer that you have mounted the transduc-
ers according to the selected mode and spacing requirements and are ready to start operation.
To start the [Install Complete?] routine for an original installation:
Select any transit-time mode (e.g., Clamp-On or Flow Tube) and press the <Right Arrow>.
Press <Down Arrow> and scroll to the [Pick/Install Xdcr] menu cell. Press <Right Arrow>.
Install transducers as required (refer to Section 3 for procedures).
After transducers are properly mounted, the flow computer completes its Initial Makeup command and
the [Install Complete?] menu cell appears.
To access the [Install Complete?] option list, press the <Right Arrow>.
Press <Down Arrow> and scroll to the [Install Complete?] menu cell and then press <ENTER>.
Press <ENTER>. The [Install Complete?] menu cell will indicate [Yes] after the 1020 is success-
fully installed.
NOTES
z
Mount the transducers using the selected mode (direct or reflect). Please refer to the trans-
ducer mounting procedures detailed in Section 3.
z
When using a mounting track or a spacer bar in reflect mode, locate the first trans-
ducer at the Reference Index and the second transducer at the recommended Number Index.
z
If transducers are mounted independently, you must use the recommended distance; Ltn to
space the transducers.
z
You must use the proper sonic coupling compound. See “Recommended Sonic Coupling
Compounds” in Section 3 for appropriate type and part number.
z
The pipe must be completely filled with a liquid, which can be either flowing or at zero flow.
