Abstract

PURPOSE:To exactly measure and display the boundary level of storage liquids by receiving the detection signals from optical sensor units in accordance with a float which moves upward and downward in a vertically long inside cylinder according to the displacement of a liquid level and displaying the liquid level. CONSTITUTION:A vertically long outside cylinder 1 is closed at apertures 2, 3 and the vertically long inside cylinder 6 has apertures 7, 8 to be infiltrated with the upper layer and lower layer liquids A, B. The float 13 in the cylinder 6 moves upward and downward according to the displacement of the boundary face C of the liquids A, B. The cylinder 6 is made of a light transmissive material and is provided with the plural sensor units 15 facing each other on the opposite surface. Laser light is inputted to said unit from a liquid level display device. The laser light transmits the light transmissive wall and the liquids A, B from an input 15 side and arrives at an output 15d side. The laser light is shut off and is displayed on the lamp of the display device if the float 13 is interposed. The measurement and display of the boundary level of a tank in which two kinds of the liquids are stored are thereby exactly executed.
