WIPO Patent Application WO/2013/145991
Kind Code:
A1
Abstract:
A level (1) is provided with: a measurement base (2) in which a reference plane (2A) that is brought into contact with a measurement surface is disposed; and a first bubble tube (6A) and a second bubble tube (6B) which form a pair and are mounted on the measurement base (2) with liquid (8) and one first air bubble (10) being sealed therein and the base end sides thereof being connected to each other so as to communicate with each other such that the first air bubble (10) is movable. This level (1) can measure the inclination state without being affected by a change in the size of the air bubble sealed in the bubble tubes, thereby making it possible to facilitate measurement work and suppress the production cost.
