<p>The device for controlling and measuring of inclination (level), operated by buoyancy and consisting of a closed vessel (6) shaped like a parallelepiped or a closed vessel (17) shaped like a circular segment. The vessels are filled with liquid with floats (11) that are tied by the line (10) to the bottom or, with the circle-segment shaped vessel, a lateral side of the vessel. The upper end of the float is shaped like a cone with the tip (11a) turned upwards. At the vessels there are engraved lines (12) and (18) with numbers denoting degrees or millimeters, to show inclination. The vessels (6) or (17) are built in or fitted on consoles shaped like flat or profiled bars, of various forms and sizes, to be used as levels for controlling and measuring of inclination of planes in various trades, especially in civil engineering. The device enables control and measurement of inclination simultaneously with vertical and horizontal planes.</p> |
