Application

Meteorological monitoring station：

◉Ultrasonic wind speed and direction sensor can provide high precision and high resolution wind speed and direction data. Compared with traditional mechanical anemometers, it has no mechanical parts, no mechanical wear and start-up wind speed restrictions, and can respond to wind changes more quickly and accurately.

Aerospace field:

◉In airports, ultrasonic wind speed and direction sensors are widely used near runways and around towers. Its high precision measurement characteristics allow the airport to more accurately grasp the wind conditions on the take-off and landing runway.

Ship navigation safety:

◉Ultrasonic wind speed and direction sensors installed on the ship provide the crew with real-time information on wind conditions at sea. In the ocean voyage, the crew can adjust the course and speed of the ship according to this information to ensure the stability and safety of the ship.

Ecosystem research:

◉In ecosystem research, wind speed and direction have important effects on vegetation growth, seed dispersal and soil erosion. Ultrasonic wind sensor can help researchers quantify these effects.
