Figure 1 is a side view of the liquid level detection device of the present invention. The vertical section of the transparent tube shows the state of the liquid level when the liquid level is in the process of falling, and Figure 2 shows the state of the liquid level when the liquid level is in the process of rising. It shows the state of the liquid level at a certain time. FIG. 3 is a plan view of the liquid level detection device of the present invention, in which the transparent tube is cut along a horizontal plane that includes the path of the light beam. Fig. 4 is a diagram showing the relationship between changes in liquid level height and changes in optical sensor output, and Figs.
5 and 6 are similar to FIGS. 1 and 2, FIG. 7 is similar to FIG. 4, and FIG. 8 is similar to FIG. Corresponds to Figure 3. Explanation of symbols: 101...transparent tube body, 102...
...Transparent liquid, 103...Liquid level, 104...Light source, 105...Light ray course, 105a...Light ray course when no transparent liquid exists, 105b...
