Ultrasonic Wind Speed & Direction Integrated Sensor

NBL-W-21GUWS Ultrasonic Wind Speed & Direction Integrated Sensor Product Overview 

The NBL-W-21GUWS Ultrasonic Wind Speed & Direction Integrated Sensor is a fully digital and high-precision instrument designed to quickly and accurately measure wind speed and wind direction. Equipped with a built-in signal processing unit, it can output signals according to user requirements and optionally integrate additional elements such as temperature, humidity, atmospheric pressure, PM2.5, PM10, noise, solar radiation, and rainfall.

With a rugged structural design, the sensor ensures reliable operation in harsh weather conditions. It is widely used in meteorology, environmental monitoring, airports, ports, laboratories, industrial and agricultural applications, and transportation sectors. 

 NBL-W-21GUWS Ultrasonic Wind Speed & Direction Integrated Sensor Key Features 

 High Accuracy Measurement: Utilizes ultrasonic technology to provide precise wind speed and wind direction data, avoiding errors of traditional anemometers.

 Durable & Reliable: Built with a high-strength design to ensure long-term stable operation in harsh weather conditions.

 Multi-Function Integration: Optional integration of multiple sensors (temperature, humidity, air pressure, PM2.5, etc.) for multi-dimensional monitoring.

 Strong Anti-Interference: Resistant to external interference from radio, radar, and vibration sources, ensuring data accuracy. 

Ultrasonic Wind Speed & Direction Integrated Sensor Working Principle 

The NBL-W-21GUWS sensor calculates wind speed and direction by measuring the ultrasonic transit time between the north–south (N-S) and west–east (W-E) transducer pairs. For example, when the wind blows from the north, the transit time from N to S will be shorter than from S to N, allowing accurate calculation of wind speed and direction. This method is not affected by temperature or other environmental factors.

Ultrasonic Wind Speed & Direction Integrated Sensor Installation Notes 

 Avoid interference sources: Ensure the sensor is not affected by radio/radar transmitters, ship engines, or mechanical vibration sources.

 Do not install parallel to radar scanning devices; maintain at least a 2-meter distance.

 Avoid installation near trees, poles, or high-rise buildings that may cause airflow disturbances.

 Recommended height: 10 meters above ground in open areas, or 1.5 times the building height, avoiding obstruction overlap.

Ultrasonic Wind Speed & Direction Integrated Sensor Application Scenarios 

 Meteorological Monitoring: Real-time wind speed and direction measurement for weather stations.

 Environmental Monitoring: Supports atmospheric condition assessment for environmental protection projects.

 Aviation & Ports: Provides accurate wind data to ensure safe operation of flights and vessels.

 Industrial & Agricultural Applications: Monitors outdoor conditions for process control and field operations.

Installation Standards (per WMO recommendations)

In open areas, installation height should be above 10 meters from ground level, free of obstructions.

Sensor should be placed away from surrounding buildings and vibration sources to ensure measurement accuracy.
