Principle of level

The level tube of the level meter is made of glass. The inner wall of the level tube is a curved surface with a certain radius of curvature. The tube contains liquid. When the level meter is tilted, the bubbles in the level tube move to the raised end of the level meter to determine the level of the horizontal plane. position. The greater the radius of curvature of the inner wall of the vial, the higher the resolution, and the smaller the radius of curvature, the lower the resolution. Therefore, the radius of curvature of the vial determines the accuracy of the level.
The spirit level is mainly used to check the flatness, straightness, verticality of various machine tools and workpieces, and the horizontal position of equipment installation. Especially when measuring the verticality, the magnetic level can be absorbed on the vertical working surface without manual support, which reduces labor intensity and avoids the measurement error of the level caused by human heat radiation.

The bottom and side of the level are both a right-angled structure with a length of 2000mm, and the accuracy is generally (0.02-0.025) mm/m. If the user has special requirements, it can be customized separately. The zero adjustment structure of the level gauge has unique features, compared with the conventional structure: 1. It is easy to adjust the zero. 2. After adjustment, the zero position is not easy to change. As shown in Figure 1. When the V-groove surface at the bottom of the spirit level rotates around the mandrel 5, if the bubble moves, the adjustment screw 2 can be used to meet the requirements. This item has been adjusted before leaving the factory and generally remains unchanged.

The structure of the spirit level varies according to the classification. The frame level is generally composed of the main body of the level, the horizontal level, the adiabatic handle, the main level, the cover and the zero adjustment device. The ruler level is generally composed of the main body of the level, the cover, the main level and the zero adjustment device.

A level is a measuring tool with a level as a measuring and reading element. The level is a sealed glass tube, and the longitudinal section of the inner surface is a circular arc surface with a certain radius of curvature. The glass tube of the level contains liquid with a small viscosity coefficient, such as alcohol, ether and their mixtures, etc. The part without liquid is usually called the level bubble. There is a certain relationship between the radius of curvature of the longitudinal section of the inner surface of the glass tube and the index value. According to this relationship, the inclination of the measured plane can be measured.
