Method and apparatus for character isis design of the consistency of liquid - solid - suspensions, silts or soft below a surface of the water sediment.

摘要

A method for characterizing the consistency of liquid - solid - suspensions, silts or soft sediments below a water surface by means of one or more ultrasonic sensors (7, 8),characterized in that a depth profile (6) is produced with respect to the measured variables• Damping (7)• Speed of sound (7)• Acoustic impedance (7).
