[0035] The leveling tube level 5 is a tool for measuring the elevation of the ground or the horizontal line. It is commonly used in civil engineering, construction engineering and surveying engineering to determine the height of the ground or the horizontal degree of the horizontal line. The basic working principle of the leveling tube level 5 is to use the horizontal stability of the liquid in the pipe. It consists of a long and narrow pipe, usually made of glass, sealed at both ends. The pipe is filled with liquid, usually water or ethylene glycol solution to ensure that it is not easy to evaporate. There is a bubble in the middle of the pipe, and the position of the bubble depends on the horizontal state of the pipe. When using the leveling tube level 5, people place it at the position to be measured, ensuring that its base is stable and placed horizontally. Then observe the position of the bubble in the pipe. If the bubble is on the mark line in the middle, then the pipe is horizontal. If the bubble deviates from the mark line, then the pipe is not horizontal and needs to be adjusted until the bubble is in the middle.
