Dumpy level and auto level are two different leveling instruments used in surveying. To choose between these two instruments a surveyor must know the differences between them. The main differences between dumpy level and auto level are given below.
|Dumpy Level||Auto Level|
|1||In the dumpy level survey, staff reading need to be adjusted as inverted level staff reading is seen in the eyepiece.||In the auto level, no adjustment for staff reading is required as the actual reading is seen from the eyepiece.|
|2||In the dumpy level, to level the bubble, one has to keep bubble parallel to two leveling screws and then right angle to the third screw.||In the auto level, the bubble can be adjusted from any side and any angle with any 3 screws available.|
|3||Line of sight is manually adjusted in dumpy level.||The auto level has an internal compensator mechanism which automatically adjusts the line of sight.|
|4||It difficult to make an accurate measurement with dumpy level.||The measurement accuracy of the auto level is higher than the dumpy level.|
