Handling ghost echoes in still pipes
The Track First Echo function can eliminate ghost echo problems below the product
surface. When enabled, the first echo above threshold will always be considered as the
surface echo.
Ghost echoes may occur in still pipes because of multiple reflections between the pipe
wall, flange, and antenna. In the echo curve, these echoes appear as amplitude peaks at
various distances below the product surface, see
