PROBLEM TO BE SOLVED: To solve the problems commonly associated with conventional liquid level measuring system such as higher cost due to the adoption of electrical detection means, complication of a system, too many number of component parts, or difficulty in simply and accurately indicating the attainment of specific liquid level. SOLUTION: To solve this problem, this system for indicating the attainment of predefined liquid level is provided. For a liquid container and a liquid column of this system, a floating body is inserted therein to vertically be sandwiched with stopper members installed at two places of both the liquid container and the liquid column, a floating body stop is provided so as to lock the floating body to the predefined position when liquid level has reached the position, allowing the visibility of the floating body from the outside of the container, only in that position. This container structure enables observation of the floating body from the outside the container to determine whether liquid measure increases or decreases from the given value.
