APPARATUS FOR MEASURING LIQUID LEVEL

摘要

PURPOSE: A liquid level measurement apparatus is provided to enhance the reliability through the minimization of the movement range of a float by restraining the movement direction of the float in a vertical direction. CONSTITUTION: A supporter(25) has a through hole(25a). A guide member(30) is slidably inserted into the through hole(25a). A float(40) is connected to a lower portion of the guide member(30). A position sensor(50) measures a liquid level. the supporter(25) is provided on the upper portion of the inner side of a container(20). the through hole(25a) is formed in the vertical direction with respect to the supporter(25), that is, in a level variation direction of remaining liquid. The movement of the supporter(30) is restrained in the vertical direction by the through hole(25a).
