Abstract

PURPOSE:To detect the liquid level accurately, by providing the prism and glass rod of U shape and observing the light through the optical glass rod separated with prism, through the change in the height of folded part of glass rod. CONSTITUTION:The height of folding part of the glass rods 1-1, 1-2... of U shape of a plurality is changed, and they are made orthogonal and fitted around the liquid surface of measured liquid. The prism 2 is provided near one end of the glass rods 1-1, 1-2.... When white light such as the sun light is incident ot the prism 2, the light is separated and introduced to one end of the glass rods 1-1, 1-2... for a given wave length range, and it is outputted on another end via the folding parts. The curvature of the folding parts is sufficiently made small so that the light can not almost reach the other end when this part is incontact with the liquid. When the liquid level is increased, since the visual field is changed, the liquid level can accurately be detected.
