Abstract
A method of measuring a liquid level of a cell culture solution stored in a cell vessel, includes: irradiating the cell culture solution with at least two kinds of light beams including a first light beam having a first wavelength and a second light beam having a second wavelength; measuring a first absorbance of the cell culture solution with respect to the first light beam, and a second absorbance of the cell culture solution with respect to the second light beam; and determining a liquid level of the cell culture solution based on the first absorbance and the second absorbance.
