1-8 Programming Site Data
Pipe Data
If a standard transducer is being used, the programming sequence
should be rejoined at this point.
1.
Enter the known pipe outside diameter or circumference, then use
the pull-down menu to select the units. Press
Next Item/Enter
.
Obtain the required information by measuring either the pipe
outside diameter (OD) or circumference at the transducer
installation site. The data may also be obtained from standard pipe
size tables found in
Sound Speeds and Pipe Size Data manual
(914-004). Available units are shown in Table 1-3 below.
2.
Enter the know thickness of the pipe wall and press
Next Item/
Enter
. If the pipe wall thickness is not available, look up the value
in a table of standard pipe size data which can be found in Sound
Speeds and Pipe Size Data manual (914-004).
IMPORTANT:
Because the units cannot be independently chosen for
this parameter, the value must be entered in the same
units used for the pipe OD.
3.
Enter the path length of the ultrasonic signal, then use the pull-
down menu to select the units. Press
Next Item/Enter
.
Note:
If a spoolpiece was ordered with the meter, the transducer
signal path length
(P)
and the transducer signal axial length
(L)
are engraved on the flowcell and/or are included in the
documentation supplied with the meter. For on-site transducer
installations, refer to Appendix C,
Measuring P and L
Dimensions , in the Startup Guide for instructions.
