10-16 Diagnosis and Troubleshooting
Clamp-on Transducer Problems (cont.)
If the coupling or pipe wall are not the problem, try relocating the
transducers using the following method. However, before
beginning, make sure the transducers are not located on or near
pipe welds or seams:
Move the upstream transducer about 1/2 inch (12.7 mm) closer
to the downstream transducer. If this resolves the problem, you
must modify the “S” dimension programmed into the
TransPort by using the following steps:
1. Press [PROG] .
2. Press [F2] to select “PIPE.”
3. Press the up arrow key [] until the transducer spacing
appears.
4. Use the numeric keys to enter the transducer spacing Subtract
0.5 in. (12.7 mm) from the original “S” and enter the new “S”
dimension.
5. Press [ENT].
Move the downstream transducer about 1/2 inch (12.7 mm)
closer to the upstream transducer. If this resolves the problem
you must modify the “S” dimension programmed into the
TransPort by using the following steps:
1. Press [PROG].
2. Press [F2] to select “PIPE.”
3. Press the up arrow key [] until the transducer spacing
appears.
4. Use the numeric keys to enter the transducer spacing Subtract
0.5 in. (12.7 mm) from the original “S” and enter the new “S”
dimension.
