Definition, principle, application and advantage of visibility meter

With the continuous development of society and economy, transportation facilities have become a necessity for people to travel, and visibility, as one of the important indicators of traffic safety, has received more and more attention. Visibility meter as one of the main equipment to measure and monitor visibility, but also with the continuous improvement of traffic safety awareness and gradually become more and more popular equipment. This paper will introduce the definition, principle, application and advantages of visibility meter.

Definition:
Visibility meter is a professional instrument used to measure visibility in the atmosphere. It is one of the main tools for visibility measurement and monitoring in traffic, meteorology and other fields, and can provide accurate measurement and monitoring data.

How it Works:
The principle of the visibility meter is based on the optical scattering characteristics of suspended matter in the atmosphere such as fog, oil fog, dust, etc. It will emit a beam of infrared light into the atmosphere, and evaluate the visibility by receiving the scattered part of the suspended matter. The monitoring work on the instrument is basically based on the principle of optical scattering.

Applications:
Visibility meter has been widely used in aviation, automobile, railway, Marine and subway transportation. It provides real-time and accurate visibility data to help drivers drive safely and prevent accidents. In addition, visibility meters are also widely used in meteorological, military, environmental protection and other fields for real-time monitoring of air pollution, weather changes and so on.

Advantages:
1. High accuracy: The visibility meter can provide real-time and accurate visibility data, and the data measured by the instrument is very accurate.
2. High safety: The visibility meter does not need to contact the measured object, so it is very safe in the case repair, and avoids damage to the accuracy and instrument performance.
3. Intelligent: With the continuous development of science and technology, many visibility meters have been developed in the direction of intelligence, which can be networked with other equipment for remote monitoring and control. In some special environments, it can even perform automatic control and intelligent judgment.

In SUMMARY:
Visibility meter as a professional measurement and monitoring equipment, has been widely used in aviation, railway, meteorology, military, environmental protection and other fields, for traffic safety and environmental protection are of great significance. Due to its advantages of accuracy, safety and intelligence, it is bound to become one of the main means of visibility measurement and monitoring in the future development, and make more important contributions to the development of society and human beings.
