C.4.4 Surface echo tracking
The Surface Echo Tracking function can eliminate ghost
echo problems below the product surface. This may occur
in Still-pipes because 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, select the Always Track First Echo
check-box making sure there are no disturbing echoes
above the product surface when this function is activated.
