摘要： The invention relates to a method and a device for quantitive determination of a number and size of particulate components contained in a medium flowing along a flow channel. Ultrasonic waves are coupled into the flowing medium, which are reflected at least partially by the particulate components and reflected ultrasonic wave portions which are detected in a ultrasonic time signals, on which the quantitive determination is based. Amplitude values associated with the individual ultrasonic time signals, are detected which are each greater than an amplitude threshold value established for each ultrasonic time signal: The detected amplitude values are assigned to values describing the size and the number of the particulate components.
