🕑 Reading time: 1 minuteLevels are the different instruments used for leveling in surveying. There are various types of levels such as dumpy level, Y level, cushing’s level, tilting level, cooke’s reversible level and automatic level instruments for leveling in surveying. The process of measuring vertical distances in surveying is called leveling. To perform leveling, we need some level instruments to focus or to read the object. Nowadays, the technology also introduced in surveying and so many easy measuring instruments are designed. Here we discuss about the different levels used in leveling.
Types of Levels Used in LevelingFollowing are the types of different levels used for leveling in surveying:
1. Dumpy LevelDumpy level is the most commonly used instrument in leveling. In this level the telescope is restricted against movement in its horizontal plane and telescope is fixed to its support. A bubble tube is provided on the top of the telescope. But however, the leveling head can be rotated in horizontal plane with the telescope. The telescope is internal focusing telescope is a metal tube contains four main parts as given below.
