Description of the Related Art In general, various methods are known for detecting the presence or absence of liquid and the position of the liquid level in a tank or container whose interior cannot be seen. For example, there are two methods: attaching a sight glass or glass tube level gauge to the container and directly checking the liquid level, inserting a liquid level gauge rod and measuring the height of the liquid adhering to it, or using various sensors to measure the height of the liquid. There are methods to measure the liquid level visually, but these methods have problems such as being easily broken, difficult to see, and having a complicated and expensive structure.

What is this tissue? When one end of the nuclear tissue is immersed in a volatile liquid, the volatile liquid penetrates into the tissue due to capillary action or surface wetting phenomenon, and even if the volatile liquid evaporates from the surface or cross section of the tissue, one end of the nuclear tissue remains. It has the property of retaining volatile liquid as long as it is replenished.

。When a volatile liquid is supplied to the absorption part of the volatile liquid indicator of the present invention by immersing it below the liquid level L (Figs. 1 to 4) of the volatile liquid in the sample, The volatile liquid penetrates into the tissue of the discoloration layer by capillary action or surface wetting phenomena, and the discoloration layer is filled with the volatile liquid. Then, due to the properties of the color change layer, the transparency becomes higher than when it is dry, and the color of the substrate becomes visible through the color change layer onto the display surface. In this case, if the color change layer is white, a color similar to that of the substrate will be observed on the display surface, and if the color change layer is colored, a composite color of the substrate and color change layer will be recognized.

在の有無または液位を検知することができる。The volatile liquid in the grooves in the color-changing layer evaporates from the volatile part of the volatile liquid indicator, but as long as the volatile liquid continues to be replenished from the absorption part, the color of the display surface will not change. When the liquid level drops from the bottom to Lo in Figures 1 to 4, the liquid is no longer replenished from the absorption part, and the volatile liquid continues to evaporate from the volatile part, so the inside of the discoloration layer dries and the discoloration layer Due to its nature, the transparency is reduced, and the color of the surface layer of the discolored layer becomes mainly visible. That is, by changing the color of the display surface of the volatile liquid indicator of the present invention, it can be determined whether the volatile liquid in the sample is present at the absorbing portion or not. By immersing the absorbent part under the liquid surface again, the presence or absence of the volatile liquid or the liquid level can be detected repeatedly in the same manner.

要水分の存在を示す。The shape of the volatile liquid indicator of the present invention can be arbitrarily designed depending on the purpose of use, place of use, and method of use so that the change in color of the display surface can be easily recognized. In general, a long and thin plate is convenient, but when detecting the presence or absence of water in soil in, for example, agriculture, horticulture, or civil engineering work, the lower end is inserted into the soil, so the shape shown in Figure 5 is used. It is convenient if the lower end has a pointed shape. In this case, insert the absorber 5 so that it is located at an appropriate depth below the soil surface G.If there is enough water at the absorber's position to be absorbed by the roots of plants, some of the water should be inserted. penetrates into the discolored layer (not shown), and the color of the display surface at that time indicates the presence of necessary moisture in the soil.
吸収部の位置に十分量の水がなくなると揮発部からの水
の蒸発に見合う水の補給が途絶えるから表示面の色が変
化して渇水を警告する。When a sufficient amount of water runs out at the absorption section, the supply of water to match the evaporation of water from the volatile section is interrupted, and the color of the display changes to warn of water shortage.

That is, a 50 m beaker was filled with water to a height of 2C11, and the display body 3 was vertically inserted and fixed so that the lower end in the longitudinal direction was located at a height of ICII from the bottom of the beaker. Water entered the color changing layer from the entire surface of the display body 3 below the water surface (absorbing portion 5) and filled the entire color changing layer 1. At this time, the display surface 4 took on a purple color.

When the water in the beaker was left as it was and the water in the beaker evaporated, the display surface 4 turned reddish-pink.

できることが確認できた。The lower end of the display body 3 was cut into a sharp shape as shown in FIG. 5 to produce a volatile liquid indicator. (Figure 5) The lower tip of this volatile liquid indicator was inserted into a flower pot filled with Kanuma soil, and water was applied to the entire surface from above the pot. The indicator turned green when water seeped into the soil. When the soil was left for several days, the display surface 4 of the indicator turned yellow, and when the soil was examined, no free water was found and the surface of the soil clod was dry. When I watered the entire surface of the pot again, the indicator turned green. The same results were obtained even if the same operation was repeated, confirming that the method can be used repeatedly to measure the presence or absence of available moisture in the soil.
