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.
