When where dumpy levels invented?

What is a dumpy level used for

A auto level or dumpy level or builders level is mainly used in the surveying and construction industries to transfer, measure, or set out horizontal lines.

How is a Auto level used?

the builders level is attached to a tripod and set to a level position by manipulating the foot screws. the user then looks through the eye piece at a 5 meter by 5 section staff,  that is held in place by a second person.

The measurement is usually taken from a point of known height that has been determined in a previous survey. or if this is not possible from a point with a assumed height.

What is the difference between a dumpy level and a auto level?

The main difference between auto level and a dumpy level is that internally a auto level has a free hanging prism (compensator) that is capable of automatically compensate for the last few seconds that the level is out. A dumpy level does not have this feature and requires a skilled operator to set the level manually in all four quadrants.
