How does an auto level work?

How does an auto level work?

An automatic level, self-levelling level, or builder’s auto level includes an internal compensator mechanism (a swinging prism) that, when set close to level, automatically removes any remaining variation. This reduces the need to set the instrument base truly level, as with a dumpy level.
