Verification Procedure with Fluid
Recommended actions
Any of these options may be used to block false echoes:
Raise general surface threshold to about 300 mV above false echo, but not more than
50% of height of surface peak.
Interface peak not found
Figure 4-5. Echo Curve Plot Indicating Amplitude Threshold for the Interface Peak too High
If the interface threshold is too high, the signal amplitude peak at the interface between the
upper and lower products is not detected.
Recommended actions
Lower interface threshold, to a level that is 50% of the interface peak.
