Abstract

PURPOSE:To prevent the occurrence of a measuring error of the snow coverage by arranging a plurality of photoelectric elements which face light receiving surfaces thereof downward at a certain spacing respectively in a line vertically inside a long transparent tube standing on the ground. CONSTITUTION:A plurality of light receiving surfaces m of the photoelectric elements M are arranged facing to the downward in a line vertically. A dopting the output of the uppermost photoelectric element R as a standard output in a comparator 4, said output is compared with each output of each photoelectric element positioned downward in order. Thus, the depth of snow is measured by judging the existence of snow coverage. In this case, since the photoelectric elements M are set at the lower positions of the uppermost photoelectric element R for standard in a line vertically and the light receiving surface is turned downward, if the snow is sticked to one side wall of the outwall of the transparent tube houses the photoelectric elements M therein and obstructs the light, it can be received the light from another side. Accordingly, the measuring error can be prevented without the effect of measuring on the snow.
