Device for detecting liquid level

摘要

The invention relates to a device for detecting the liquid level in a transparent container and has a light source for transilluminating the container and a device for picking up and evaluating the radiation which has passed through the container. In addition, the device has a diffuser (11) arranged in the beam path of the light source, an image processing unit (15) which evaluates the radiation which has passed through the container (13), line by line, with respect to a brightness minimum, and a detector which displays the brightness minima of neighbouring lines as an image of the liquid level. <IMAGE>
