A bull's eye level showing a level position A bull's eye level showing an unlevel position Machinist bulls-eye level. A bull's eye level is a type of spirit level that allows for the leveling of planes in two dimensions — both the 'pitch' and 'roll' in nautical terms. Standard tubular levels only consider one dimension.

Conversely, the obvert level is the highest interior level, and can be considered the "ceiling" level, being the highest level of that sewer. The bottom of the sewer is called the invert from a general resemblance in construction to an "inverted" arch. [2] An inverted arch is a rounded structure with its crown facing in the downward position.
Level sensors detect the level of liquids and other fluids and fluidized solids, including slurries, granular materials, and powders that exhibit an upper free surface. Substances that flow become essentially horizontal in their containers (or other physical boundaries) because of gravity whereas most bulk solids pile at an angle of repose to a ...
