Patent attributes
There is provided a fuel oil amount indicator of a measuring apparatus in which a lifetime of the indicator can be prolonged, maintenance work can be omitted, and visibility can always be improved. In the indicator of the invention, a plurality of light emitting elements are arrayed in a matrix form, and as the light emitting elements, high-luminance LEDs are used. An outside light sensor provided in the vicinity of the indicator detects brightness of outside light, and a light emission intensity of the light emitting elements is changed in accordance with the thus detected brightness. The light emitting elements have a plurality of luminous colors predetermined to correspond to a type of fuel oil.
