4. If after adjustment of the transducers the signal strength does
not rise to above 5 percent, then an alternate transducer
mounting method should be selected. If the mounting method
was W-Mount, then reconfigure the TFX for V-Mount, reset the
TFX, move the downstream transducer to the new location and
repeat Step 3 on page 2.10.
5. Certain pipe and liquid characteristics may cause signal strength
to rise to greater than 195 percent. The problem with operating a
TFX with very high signal strength is that the signals may
saturate the input amplifiers and cause erratic readings. To
decrease the signal strength, move one transducer a small
distance radially around the pipe, as shown in Figure 2.6.
