Dumpy level

Dumpy Level

Despite the evolution of the term dumpy level design. A dumpy level to establish accurately that requires skilled use an old fashioned instrument. Device in each quadrant (see spirit level) through a full 360 ° traverse ensure correct levels need to be set. Some dumpy levels, to ensure the correct level will have a bubble level.

Where greater accuracy and error checking was often necessary Surveyors, the dumpy and one that was used by a shift of a tilting level. This tool telescope effectively without rotating head, 180 ° allows to be flipped through. Telescope is hinged to one side of the axis of the device; it's flipping (inverting the telescope) to the other side of the central axis is required. This action effectively adjusting device poor setup procedure or errors introduced by any error cancels. As an example, such as the effect of rotating it through 180 ° and the difference between spirit level bubble positions by comparing with a standard builder's level can be obtained.
An automatic level to compensate for the small tilt deviations PRISM uses a swinging.

An automatic level, self-leveling level or builder's auto level, automatically, when set close to the surface of an internal compensator mechanism (a swinging prism) that includes variation removes any residue from the surface. It's a dumpy or tilting level as well, truly reduces the need to set up the device level. Self-leveling equipment sites, the construction and the ease of use and fast set-up time surveying the preferred device.

A digital electronic level is also set level on a tripod and using electronic laser methods is a bar-coded staff reads. Staffing levels across the beam height where the staff is shown on a digital display. This type of surface such as removing a source of error and increase accuracy, by a person removes interpolation of graduation. During night time, dumpy level for accurate scale readings in conjunction with an auto-cross laser is used.
