Rosemount 3300 Series
Figure 6-5. After changing the
amplitude threshold the
transmitter detects the interface
6-6
Figure 6-4 illustrates a situation where amplitude threshold T3 is too high. The
signal amplitude peak at the interface between the upper and lower products
is not detected in this case. By adjusting amplitude threshold T3, the peak at
the interface between the upper and lower products is detected as illustrated
in Figure 6-5:
The amplitude threshold is
adjusted below the peak to allow
the interface peak to be detected
