Patent abstract

A method for the characterizing a fluid containing particles reflecting ultrasounds wherein a sample of fluid placed between two surfaces (5, 6) in a rheometer (1) undergoes stress in order to measure the rheological characteristics of the sample (8) during relative movement of the two surfaces (5,6) in relation to each other. Local ultrasound data relating to the sample (8) deformation is collected by ultrasonic-wave-measuring means (2,3,4). The invention also relates to a device for carrying out said method.
