Different types and grades of level meters: guide to selection and application

Level is an all-around player in measuring instruments, which can be divided into many types according to different structures and working principles. This paper will introduce the types and grades of level meters to help you better understand this measuring instrument.

Divide by structure

According to the different structures, the level can be divided into micro-tilt level, automatic level, laser level and digital level. Each level has its own unique characteristics and scope of application.

According to the working principle

According to the different working principles, the level can be divided into electronic level and optical level. The two levels have their own advantages and disadvantages, and users can choose according to actual needs.

grading

China's national standards divide the grades into four grades: DS05, DS 1, DS3 and DS20. Among them, DS05 and DS 1 are precision levels, which are often used in national first-class and second-class precision leveling and earthquake monitoring. DS3 leveling and DS 10 leveling are ordinary leveling, which are suitable for national third-and fourth-class leveling and general engineering leveling.

Select the DS3 level.

In highway engineering survey, we usually choose to use DS3 level. DS3 leveling is a kind of common leveling, which is suitable for national third-and fourth-class leveling and general engineering leveling. It has the advantages of high precision and convenient use.
