The blister level manufacturer believes that the level is an instrument that establishes a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between the ground points according to the leveling principle. The main components are telescope, tube level (or compensator), vertical shaft, base and anchor screws. The height measurement methods commonly used in engineering include geometric leveling, trigonometric leveling, GPS leveling and physical elevation measurement under specific objects and conditions. Geometric leveling is a widely used and high precision measurement method.

The blister level manufacturer believes that the level is an instrument that establishes a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between the ground points according to the leveling principle. The main components are telescope, tube level (or compensator), vertical shaft, base and anchor screws. The height measurement methods commonly used in engineering include geometric leveling, trigonometric leveling, GPS leveling and physical elevation measurement under specific objects and conditions. Geometric leveling is a widely used and high precision measurement method.

The blister level manufacturer believes that the level is an instrument that provides a horizontal line of sight. According to the accuracy level, it usually includes DS05, DS1, DS3, etc. Where "D" and "S" are the initials of "earth" and "horizontal" respectively, and the subscript is the accuracy index of the instrument, that is, the accidental error (in millimeters) in the measurement per kilometer. At present, the commonly used level can be divided into two types in structure: the use of level tube to obtain a horizontal line of sight "micro-tilt level" and the use of compensator to obtain a horizontal line of sight "automatic level". In addition, there is a new level-"electronic level", the use of bar code ruler, through digital image processing, automatic display of elevation and distance, so as to achieve the level of automation.

The blister level manufacturer believes that the maintenance and maintenance of the level:

1. The level is a precision optical instrument, and its correct and reasonable use and storage have a great effect on the accuracy and life of the instrument;

2. Avoid direct sunlight and do not disassemble the instrument casually.

3. Turn gently every fine adjustment, not too hard. Hand touching of the lens optics is not permitted.

4. If the instrument is faulty, it should be repaired by a person familiar with the structure of the instrument or the repair department.

5. After each use, clean the instrument and keep it dry.

The blister level manufacturer believes that leveling is a high-precision elevation measurement method, which is widely used in national elevation control measurement, engineering measurement and construction measurement. The principle of leveling is to measure the height difference between two points by reading the horizontal sight provided by the level gauge, and then calculate the elevation of the fixed point according to the known point elevation.

The blister level manufacturer believes that the electronic level, also known as the digital level, consists of a base, a level, a single barrel mirror and a data processing system. The electronic level is based on the automatic anping level, which adds a beam splitter and a detector (CCD) in the optical path of the telescope. It is a high-tech product of opto-mechatronics, consisting of a stripe coding scale and an image processing electronic system. At present, the calibration and focusing of the electronic level still need to be completed by visual inspection. After manual debugging, the bar code of the ruler is imaged on the differential board of the telescope for visual observation on the one hand, and on the other hand, it is imaged on the photoelectric sensor (also called detector) through the spectroscope of the telescope for electronic reading.
