Abstract
PURPOSE:To eliminate problems such as explosion and corrosion by improving precision by removing the cladding of part of optical fiber by regarding the part as a liquid-quantity measurement range and also by covering the cladding-removed part with a light leaking film that has vent holes. CONSTITUTION:Optical fiber 2, connecting display panel 5 to light source 1 partially led into container 6, has its cladding removed within range L of the measurement of the quantity of a liquid and the part where a core is exposed by removing the cladding is covered with light leaking film 3 through hollow part 7. While container 6 is filled with liquid 9, light leaking film 3 is compressed to contact the core hermetically, so that light from light source 1 will be emitted into liquid 9 by way of light leaking film 3. When liquid 9 is container 6 lessens below liquid-quantity measurement range L, hollow part 7 is formed again and light led to optical fiber 2 enters photoelectric converting element 4 after total reflection in the core, so that the quantity of the liquid is displayed on display panel 5.
