Abstract

PURPOSE:To measure the density of sludge in a different thickness condition only by one set of sludge density meter by forming a light passage between the outer cyinder of the double structure and a fixed inner cylinder with a predetermined spacing spaced from the inner wall thereof and fitting the piston between the outer and the inner cylinders. CONSTITUTION:The piston cylinder 33 is moved upward and the sludge 30 is taken into the spacing between the outer cylinder 31 and the fixed inner cylinder 32 and in its condition, the aount of light entering the photodetector 35 passing through the sludge layer from the measurement portion 36 of thelight source 34 is measured to obtain the density of the sludge, the piston cylinder 33 is moved downward together with the completion of the measurement, the sludge is discharged to complete the one measurement process. In accordance with this density meter, if the outer diameter of the fixed innercylinder 32 is charged without changing the inner diameter of the outer cylinder 31, the spacing between the inner surface of the outer cylinder and the outer surface of the inner cylinder can be changed arbitratily. Therefore, the density of the sludge in a plurality of conditions can be obtained with accuracy by chainging the thikness of the sludge layer entering the measurement portion 36. The light passage of the determination portion may be formed at both sides of the outer cylinder and between the inner cylinder and the outer cylinder in opposite relation.
