Level that can measure micro tilt {A WATER LEVEL ABLE TO MEASURE A VERY SMALL AMOUNT LEVEL}

The present invention relates to a leveler, and more particularly, it is possible to measure the left and right vertical and horizontal at the same time, as well as to the left and right / vertical leveler that can measure the angle of inclination and accurate angle for the slight inclination.

In general, in civil engineering and construction sites, it is important to measure the horizontal and vertical conditions, or to measure the horizontal position of a remote point from an arbitrary point, and to measure the vertical position of a remote point from an arbitrary point. Doing.

That is, the level used to measure the horizontal state at the construction site is a bubble is contained in the tube 100 is a liquid sealed inside as shown in Figure 5a when the bubble 200 is located in the center of the tube Judging by the horizontal state.

Since the level is only measuring the horizontal state along the axial direction, it is difficult to measure the horizontal state over the omnidirectional, so as shown in FIG. 5B, the bubble 200 having a circular measuring unit 300 is included therein. If it is located at the center, it is determined to be in a horizontal state, and since the position is changed over the circumference of 360 ° along the direction in which the bubble is inclined, many levels are used to measure the inclination over all directions along the XY coordinate axis.

However, according to the above-described conventional levels, it is possible to measure which measurement surface is horizontal or which direction is inclined, but it is not possible to know the inclination angle in detail. An unmeasurable problem occurred.

However, since the shape of the tilt measuring sphere is formed in a spherical shape, the distance in which the bubble in the tilt measuring sphere flows along the inner surface of the sphere is smaller than the bubble flow distance on the plane, so that the slight tilting of the tilt measuring object is limited. The problem is that the tilt measurement is difficult to observe properly.
