Abstract

The invention refers to an improved bubble level, which successfully substitutes the already known bubble level and it also has the ability to count angles of straight lines or surfaces as far as plumb is concerned directly with reading of the level without the use of any other auxiliary instrument. It includes a cylinder disc frame or a stable cylinder in relation to the frame- and needle-pointer that freely rotates around the disc's stable axis or a cylinder with a weight on the one edge of the needle in order to always give the plumb. A marked diameter of the disc or the cylinder's bases that is relevant and parallel to the needle when the working surface of the bubble level is horizontal, is forms an angle with the needle, which is an angle of horizontal level as well as a working level of the bubble level. The angle is given in degrees or any other angle measure depending on the calibration of the disc of the bases of the cylinder.
