Abstract
There is provided a liquid-level gauge for accurately measuring a liquid-level height of fluid to be measured. In the liquid-level gauge, a float having a uniform cross-sectional form in the height direction and a specific weight value small than that of liquid is dipped in the liquid. The float is supported by an optical fiber at a constant height such that its upper end always projects from the liquid level. One end of the optical fiber is connected to an optical fiber strain gauge and a strain detector is turned round between fiber support members. When the float receives buoyancy from the liquid, tension is applied to the strain detector of optical fiber to generate strain therein. By detecting the strain by means of an optical fiber strain gauge, a liquid-level height can be measured.
