Visibility Measuring Instrument

NiuBoL Visibility Measuring Instrument Product Introduction 

NiuBoL Visibility Meter Working Principle  

The NiuBoL Visibility Meter utilizes the forward scattering principle. It precisely measures the suspended particles in the atmosphere by emitting forward-scattered light at angles smaller than 90 degrees within the sampling area. The instrument calculates the Meteorological Optical Range (MOR) by measuring the intensity of scattered light and processes the data through a microprocessor controller. It is suitable for visibility measurements less than 100km and is highly effective in dealing with the impact of fog, haze, and smog. The design concept emphasizes not only measurement accuracy but also environmental protection and intelligent management, providing strong data support for meteorological monitoring, traffic safety, and environmental protection.

Core Technical Advantages of the Visibility Meter  

- Aerosol Forward Scattering Principle: By precisely measuring the scattered light from minute particles in the air, it calculates the current visibility in real-time. Compared to traditional transmissive visibility meters, the forward scattering instrument has higher resolution and faster response time. It remains stable and accurate even under extreme weather conditions, ensuring the real-time and reliable nature of the data.

- Intelligent Management and Convenient Operation

  - Automatic Calibration: The built-in data processing system features automatic calibration, reducing human errors.

  - Wireless Transmission: Data is wirelessly transmitted to the cloud platform, allowing users to view real-time visibility data, historical records, and trend analysis through mobile apps or web platforms.

Installation Position Selection for the Visibility Meter 

General Installation Requirements:  

1. Representativeness:  

   The measurement value at the location of the visibility meter should represent the surrounding weather conditions. Therefore, the installation should be in a place without large buildings, trees, or other objects that may generate thermal effects or obstruct precipitation within at least 100 meters. Such obstacles could influence the local climate and affect the measurement results. 

2. No Obstacles:  

   The installation site should be free of any obstacles or reflective surfaces that may affect optical measurements. The transmitter and receiver should have an unobstructed line of sight to ensure the accuracy of the measurement results. Additionally, avoid installing the device near strong light sources, such as direct sunlight, snow surfaces, or sand surfaces, as they may interfere with the measurements. 

3. Pollution Sources:  

   The transmitter and receiver should be positioned away from any significant pollution sources, such as vehicle exhaust. These pollution sources may introduce additional particulate matter, impacting the visibility measurements.

Specific Installation Location Recommendations  

1. Meteorological Stations:  

   In meteorological stations, the visibility meter should be installed in open, unobstructed areas to ensure representative measurement results. Grounding protection for the equipment should also be considered to prevent lightning and radio frequency interference.

2. Highways:  

   For highway visibility monitoring, the instrument should be installed near toll stations or service areas. This ensures stable power supply and safe management of the equipment, while also facilitating periodic calibration and maintenance. The installation site should avoid areas prone to localized smoke to maintain measurement accuracy.

3. Airports:  

   When installed at airports, the visibility meter should be placed near runways or meteorological observation towers. These locations provide accurate runway visibility information, which is crucial for flight safety. Consideration should also be given to the equipment's wind resistance and stability to ensure proper functioning under harsh weather conditions. 

Other Considerations  

1. Installation Height:  

   The installation height of the visibility meter should be moderate, typically around 1.5 to 2 meters above the ground. This helps avoid interference from ground-level factors while ensuring the device can capture sufficient aerosol scattering light signals.

2. Maintenance Management:  

   After installation, regular calibration and maintenance should be carried out. This includes cleaning the transmitter and receiver mirrors, checking power and communication lines, and other tasks to ensure the accuracy and reliability of the device and extend its lifespan. 

In conclusion, the installation position of the visibility meter should be selected based on the specific application scenario and requirements. When choosing the installation site, factors such as representativeness, lack of obstacles, pollution sources, and specific location recommendations should be considered. Furthermore, regular calibration and maintenance are essential to ensure the accuracy and reliability of the device.

Conclusion:  

The NiuBoL Visibility Measuring Instrument, combining advanced optical sensor technology with intelligent design, provides efficient and accurate data support for meteorological monitoring, environmental protection, traffic safety, and other fields. Its innovative technical features not only enhance measurement precision but also improve the reliability and adaptability of the equipment, making it an indispensable environmental monitoring tool in the construction of modern smart cities.
