The level gauge is vertically installed on the outside of the tank for storing fluids such as water, oil, or lubricating oil. The level gauge can visually check the level of the fluid that has risen into the level gauge due to the static pressure of the fluid stored in the tank. It is a kind of measuring instrument that makes it possible to check the flow rate (ie, level) of the fluid.

Thus, conventionally, as shown in Figure 1, the lower portion of the tank (T) is provided with a lower gauge body 11, the upper portion of the tank (T) is provided with an upper gauge body 12, these gauge bodies ( 11 and 12 were connected to each other by gauge coupler 13 such that level gauge 10 was vertically hypothesized to tank T.

In addition, by inserting the glass tube 14 inside the lower gauge body 11 and the upper gauge body 12, respectively, these glass tubes 14 are arranged side by side in the vertical direction, the glass tube 14 spaced up and down The fluid was allowed to flow by the gauge coupler 13 between them, allowing fluid to be granulated through them.
