Section 2
After transducers are properly mounted, the flow computer completes its Initial Makeup com-
mand and the [Install Completed?] menu cell appears.
To access the [Install Completed?] option list, press the <Right Arrow>.
Press <Down Arrow> and scroll to the [Install] menu cell and then press <ENT> (un-
less otherwise directed to do so by Controlotron’s Technical Service Department).
NOTES
l Mount the transducers using the selected mode (direct or reflect). Please refer to the
transducer mounting procedures detailed in Section 3.
l 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.
l If you are mounting the transducers independently, you must use the recommended dis-
tance; Ltn to space the transducers.
l You must use the proper sonic coupling compound. See “Recommended Sonic Coupling
Compounds” in Section 5 for appropriate type and part number.
l The pipe must be completely filled with a liquid, which can be either flowing or at zero
flow.
2.4.7 THE Ltn VALUE 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 (see Section 3 for details).
Note that Ltn may be a negative number for direct mount on very small pipes where the
transducer spacing overlaps.
2.4.8 HOW TO USE [INSTALL COMPLETED?]
Use the [Install Completed?] menu cell to inform the flow computer that you have mounted
the transducers according to the selected mode and spacing requirements and are ready to
start operation.
To start the [Install Completed?] routine for an original installation:
Select [Dual Path Flow]and press the <Right Arrow>.
Press <Down Arrow>. Scroll to the [Pick/Install Xdcr] menu cell. Press <Right Arrow>.
Install transducers as required (refer to appropriate 1010 Field Manual for procedures).
