Ultrasonic wind speed and direction meter is an advanced equipment to measure wind speed and direction through ultrasonic waves. Its working principle is to utilize the characteristics of ultrasonic wave propagation in the air to deduce the wind speed and direction by measuring the difference between the ultrasonic wave propagation speed and the airflow speed in the wind direction. When the propagation direction of ultrasonic waves is the same as the wind direction, its propagation speed will be accelerated; conversely, if the propagation direction of ultrasonic waves is opposite to the wind direction, its propagation speed will be slowed down. Therefore, under fixed detection conditions, there is a certain functional relationship between the speed of ultrasonic wave propagation in the air and the wind speed. By accurately calculating this relationship, accurate wind speed and wind direction measurements can be obtained. Since the speed of the sound wave propagating in the air is greatly affected by the temperature, the ultrasonic wind speed and direction meter is designed with two detection channels in opposite directions, so that the effect of temperature on the speed of the sound wave can be canceled out by each other, thus further improving the measurement accuracy.
It is a lightweight, durable and easy-to-use device that features high-precision measurement of wind speed and direction. Since it has no moving parts, maintenance and on-site calibration are not required. Customers can select different wind speed units, output frequencies and output formats according to their actual needs. In addition, the option of a heating unit provides additional ease of use in cold weather conditions. The unit can be easily connected for use with a computer, data collector or other acquisition device with RS485 or analog output capability. If required, multiple units can be networked together for a wider range of applications.
The Ultrasonic Wind Velocity and Direction Meter is a highly sophisticated instrument capable of all-weather, long-lasting and accurate wind speed and direction measurements. Because its design overcomes the inherent shortcomings of mechanical anemometers, the device maintains stable and reliable performance in a variety of environmental conditions. Therefore, ultrasonic anemometers are gradually replacing mechanical anemometers as the mainstream wind speed and direction measurement tool.

Agricultural development will encounter some bad weather, such as typhoon, rainstorm, drought, hail, frost, etc., which will bring losses to agriculture. Setting up a meteorological and environmental monitoring system in farmland will help to improve the level of agro-meteorological environmental monitoring in the region, increase the yield of crops, and increase the ability to prevent disasters. With the development of smart agriculture, the model of weather station + Internet continues to develop, and the agricultural environment monitoring system will bring more development opportunities....
