Automatic measurement of inclination or tilt angle using a cuvette filled with liquid so that an air bubble is formed, the shadow of which interacts with a light barrier, allowing the tilt angle to be determined

摘要

Device for measurement of the tilt angle or inclination by determination of the position of an air bubble in a container (2) filled with fluid (2e) by use of a multiple light barrier (1, 3). Accordingly the shadow effect caused by the air- liquid interface (2f) on the photo-detectors is projected and evaluated.
