Abstract
PURPOSE: To make it possible to confirm accurately the water level by mounting a color filter in front of the lens of an ITV camera and monitoring the visual window of the water surface gauge with a light in a wave length range, which is easiest to monitor, by the camera and making it easy to extinguish lightness and darkness of the visual window.
CONSTITUTION: Lamp 25 in lamp housing 24 is lit, and the light ray is caused to be incident into water room 23 of water surface gauge 20. Then, while utilizing the fact that refractive indexes of the light ray are different for vapour and boiler water in water room 23, a blue filter is mounted in front of the lens of the ITV camera to monitor water surface gauge 20 with a high-refractive index blue light ray in case that the distance between water surface gauge 20 and the ITV camera cannot be takin sufficiently due to the relation of the installation position when the water level of in the vapour drum is monitored by the ITV camera. By this method, the blue light which is refracted in the part, where boiler water is filled up in water room 23, and comes out from visual window 22 is not incident into the lens of the ITV camera, so that lightness and darkness of visual window 22 can be discriminated accurately, and the water level in the vapour drum can be confirmed accurately.
