Abstract

PURPOSE:To detect a liquid level position by a simple constitution without reference to the shape of a container by making a comparison between reflected-light detection signals obtained by two photo detectors arranged at upper and lower symmetric positions with a light source between the both. CONSTITUTION:Photo detectors 3 and 3' are provided on container wall 4 at upper and lower positions symmetrical on light source 5 positioned corresponding to a fixed reference liquid level of container 1. Reflected-light detection signals obtained by those elements 3 and 3' as to wall 4 are processed by comparator 10 such as a differential amplifier, so that this simple constitution can detect the liquid level being equal the reference value, higher than the reference value or lower than the reference one without reference to the shape of the container.
