Abstract

The purpose of the present invention is to provide a liquid surface detection apparatus for determining, even in a non-contact manner, a liquid surface position with higher accuracy. For this purpose, the liquid surface detection apparatus of the present invention is provided with: a first liquid surface detection mechanism that detects, in a non-contact manner, the upper surface of a liquid in a container; a second liquid surface detection mechanism that detects, in a contact manner, the upper surface of the liquid in the container; and a control device that uses the detection result from the second liquid surface detection mechanism to correct the detection result from the first liquid surface detection mechanism. Preferably, the control device has a storage unit for storing a correction value for correcting the detection result from the first liquid surface detection mechanism. The correction value is calculated on the basis of a difference between a liquid surface position detected by the first liquid surface detection mechanism and a liquid surface position detected by the second liquid surface detection mechanism.
