ABSTRACT:
An illuminating device (6, 7) and a light sensor device (5) are each arranged on opposite sides of the sedimentometer (3). The light sensor device (5) can be adjusted in height by means of a servo-motor (18) and contains two light receivers (11, 13; 12 14) arranged one above the other. The output signals of both light receivers (11, 13; 12, 14) are fed to a controller which activates the servo-motor (18) in such a way that the quantities of light falling on both light receivers (11, 13; 12 14) during the process of sedimentation are maintained at a constant predetermined relationship to one another, with the result that the lower light receiver (12, 14) is constantly maintained at a horizontal alignment with the upper surface of the sediment in the sedimentometer (3). The height adjustment of the light sensor device (5) thus forms a basis of measurement of the height of sedimentation during the sedimentation process. A signal transmitter (20) coupled to the light sensor device (5) transmits a signal which represents the height of sedimentation, the signal being able to be continuously displayed and/or evaluated in a computer. Continuous observation of the sedimentation process is therefore not required.
