Traditionally, wind speed and direction measurements have relied on mechanical anemometers, but with the development of ultrasonic technology, people have begun to explore its application in wind speed measurements.The Ultrasonic Anemometer utilizes the properties of ultrasonic waves propagating through the air, demonstrating a faster response time and higher measurement accuracy. Therefore, the Ultrasonic Anemometer has been widely used as a wind measurement tool in meteorological monitoring and related fields.
The method determines the wind speed based on the change of ultrasonic propagation speed in the air: the speed of sound increases in a tailwind, slows down in a headwind, and is the same in the absence of wind. The instrument is usually equipped with four ultrasonic probes that both transmit and receive sound waves and work in pairs to measure relative wind speed. By analyzing the data from both sets of probes together, the wind speed and direction can be accurately determined.
The main difference between ultrasonic wind measurement and traditional mechanical wind measurement is the measurement principle and structural design:
Mechanical wind sensors rely on the physical rotation of a wind cup or vane to sense wind speed and direction, which is then converted into an electrical signal for measurement.
The Ultrasonic Anemometer, on the other hand, uses the ultrasonic time difference method to determine wind speed and direction by measuring the difference in the time it takes for ultrasonic waves to propagate through the air upwind and against the wind. With no mechanical parts, the Ultrasonic Anemometer avoids mechanical wear and tear and the effects of inertia, thus reducing maintenance requirements and improving measurement accuracy and response time.

Grid monitoring has achieved remarkable results in controlling air pollution. It can accurately locate pollution sources. By constructing a dense monitoring network in different areas, such as dividing ordinary grids in cities, setting encrypted grids in key areas, and arranging irregular grids in s...
Strawberries are fruits in spring, but with the development of greenhouse technology, we can now also eat strawberries in winter. Winter strawberries are harvested from greenhouses because they have meteorological requirements. Therefore, we can create an environment suitable for strawberry growth i...
