4.5.3 Surface Echo Tracking
The Surface Echo Tracking function can be used to eliminate problems with certain types
of ghost echoes below the product surface. This may, for example, occur in still-pipes as a
result of multiple reflections between the pipe wall, flange and antenna. In the tank
spectrum these echoes appear as amplitude peaks at various distances below the product
surface.
To activate this function, ensure that there are no disturbing echoes above the product
surface and select the
Always Track First Echo check box.
To open the Surface Echo Tracking window:

start searching or trigger any alarms.
