Auto false echo suppression
Note
• Ensure material level is below all known obstructions when using Auto False Echo
Suppression to learn the echo prole. An empty or almost empty vessel is recommended.
• Note the distance to material level when learning the echo prole and set Auto False Echo
Suppression Range to a shorter distance to avoid the material echo being screened out.
• Set Auto False Echo Suppression and Auto False Echo Suppression Range during startup, if
possible.
• If the vessel contains an agitator, it should be running.
• Before adjusting these parameters, rotate the device for best signal (lower false-echo
amplitude).
If you have a vessel with known obstructions, use Auto False Echo Suppression to prevent
false ec
ho detection. This feature can also be used if the device displays a false high level, or
the reading is uctuating between the correct level and a false high level.
The device learns the echo prole over the whole measurement range and the TVT is shaped
around all echoes present at that moment. See Auto False Echo Suppression (Page202) for a
more detailed explanation.
