A transparent measuring plate is arranged in the middle of the front of the stainless steel shell 1, and a positioning frame 4 is symmetrically arranged in the middle of the inner part of the stainless steel shell 1. A floating plate 5 is slidably connected to the outer sides of the two positioning frames 4. The floating plate 5 moves on the positioning frame 4 driven by the liquid, and then the liquid level height is conveniently checked through the transparent measuring plate. A floating air bag 6 is arranged in the middle of the inner sides of the two positioning frames 4, and the bottom of the floating air bag 6 is at the same level as the bottom of the floating plate 5. At the same time, the middle of the upper end of the floating airbag 6 passes through the middle of the top of the stainless steel shell 1 through the connecting rope 7 and is connected to the moving slider 8. The top of the connecting rope 7 sequentially passes around the first rotating disk 10, the tensioning roller 11 and the second rotating disk 12 arranged on the mounting frame 9 installed on the top of the stainless steel shell 1, and the first rotating disk 10, the tensioning roller 11 and the second rotating disk 12 are rotatably connected to the mounting frame 9. The floating airbag 6 moves upward on the inner side of the positioning frame 4 driven by the liquid, and pushes the connecting rope 7 to unwind on the first rotating disk 10, the tensioning roller 11 and the second rotating disk 12, so that the moving slider 8 moves downward on the measuring column 102, so as to facilitate the viewing of the liquid level height.

[0023] Further explanation: the interior of the stainless steel shell 1 is coated with a waterproof and anti-corrosion coating, and an extended base plate 101 is installed at the lower end of the stainless steel shell 1 below the moving slider 8, and a measuring column 102 is installed at the upper end of the extended base plate 101.
