Apparatus for measuring the turbidity of liquids, in particular for determining the sludge level in settling tanks of sewage treatment works

摘要

For measuring the turbidity of liquids, particularly for determining the sludge level in settling tanks of sewage treatment works, the invention proposes to design a turbidimeter (2), comprising a light source (3) and a photocell (4) arranged at a distance therefrom, such that the light source (3) and the photocell (4) are designed in sheet-like form, the light source (3) and the photocell (4) being at a defined distance owing to a rigid connection (17), that the turbidimeter (2) is secured in a stationary sheath (1) which is closed at the top and open at the bottom, that the turbidimeter (2) can move vertically by means of a lowering device (7, 8, 9), and that a displacement sensor (11) and a computer (10) are arranged fixedly within the sheath (1). <IMAGE>
