Abstract
A method for determining the particle concentration of a continuous medium in a receptacle, in which, a light beam from a light source is first directed through a particle-loaded, continuous medium, to the light-sensitive surface of a position-sensitive sensor, the light beam being so directed at the light-sensitive surface that the light scattered by the particles assuming, on the average, a different position than the unscattered light. The deviation of the midpoint of the scattered light on the light-sensitive surface from the midpoint of the unscattered light is subsequently determined, and this deviation is correlated to a specific particle concentration.
