The universal level bubble of the prior art generally needs to be provided with a special mounting seat in order to realize multi-directional measurement, which results in larger space required for measurement. Compared with the prior art, the method and the device only need a small measurement space.

Example 1:

the casing in this embodiment is an integrally formed structure, and a liquid injection hole is formed in a side wall of the casing, and the liquid injection hole is closed after liquid is filled into the casing through the liquid injection hole.

Example 2:

the difference between this embodiment and embodiment 1 is that the housing in this embodiment is a split structure, and the housing includes a transparent liquid storage shell 11 and a transparent sealing sheet 12, where one end of the liquid storage shell 11 in the axial direction is open, and the other end in the axial direction is closed, a circle of annular groove is formed along a circumferential side wall of one end of the liquid storage shell 11 at the opening, and the transparent sealing sheet 12 is adhesively fixed in the annular groove at the opening end of the liquid storage shell to close the liquid storage shell 11. Set up annular groove can increase and transparent cover slip between the adhesive surface area, guarantee adhesive strength and leakproofness. The closed space formed by the liquid storage shell 11 and the transparent sealing sheet 12 is filled with liquid and is provided with air bubbles 2. The inner wall of the liquid storage shell 11 in the axial direction and the inner wall of the transparent sealing sheet 12 facing the inner side of the liquid storage shell are large-radius curved surfaces which are symmetrically arranged up and down, and the axis of the liquid storage shell 11 passes through the highest point of the curved surfaces. The identification ring 14 in this embodiment is provided on the reservoir.
