The ultrasonic anemometer is developed on our proved ultrasonic technology of time difference. We have dealt with ultrasonic technology for decades of years and have accumulated rich experience in developing and manufacturing. We can provide 2D and 3D ultrasonic wind speed and direction sensors,especially our 2D ultrasonic wind sensor, it has a high cost-effective.

Ultrasonic anemometer is an ideal solution to replace traditional mechanical type wind measurement devices, it mainly have wind vane, wind turbine, windsock,etc. With a strong design and light weight, it can work well for long without worrying faulty. Meanwhile, no moving parts and anti-corrosive surface coating process make it no requirement for future maintenance and special expensive calibration.

Working Principle

The basic principle is ultrasonic time difference. The speed of sound transmission in air will be added on the upward wind flow. If ultrasound transmission direction is the same as wind direction, its speed will be increased,otherwise, its speed will become slower. Thus, under fixed condition, the transmission speed of ultrasound in air has function correspondence relationship with wind velocity. By calculation, wind speed and direction can be precisely known. When sound wave is travelling in air, its speed is heavily influenced by temperature. In order to solve the problem, our ultrasonic wind sensors measure the opposite direction of two channels. As a result, the temperature influence can be neglected.

Low Price Ultrasonic Wind Speed/Direction Sensor

This model is specially developed for low cost and low power consumption. Its power consumption is just 0.2W. It is more suitable for solar power or battery power application. Because of adopting new technology, its body is smaller. Its enclosure has ABS and metal aluminium which can meet different application. It also supports temperature and atmospheric pressure optional. It has black and white color available.

Application: 

Mainly used for family house weather station, agriculture, garden,tower crane,etc
