7.5.5 Quick setup auto false echo suppression
Use
Used to prevent the detection of false echoes in a specified range.
Use the AFES wizard if there are known installations in the application and if false
echoes are to be expected.
Notes
If possible, set the automatic false echo suppression (AFES) during commissioning by
executing the " Auto false echo suppression wizard".
Make sure that the material level is below all known installations when using the "
Auto false echo suppression wizard" to determine the TVT. Ideally the vessel should
be empty or almost empty.
Note the distance to the material level when determining the echo profile and set
the value in parameter " auto false echo suppression" to a smaller distance to avoid
suppression of the material echo.
If an agitator (whisk) is available, it should be in operation.
