[0002] A level is a device that determines the height difference between two points on the ground by establishing a horizontal line of sight. It is widely used in the field of surveying and mapping auxiliary equipment technology. The principle of the level is to measure the height difference between ground points according to the leveling principle. Its main components include a telescope, a tube level, a vertical axis, a base and a foot screw.
