  The wind speed sensor is a professional meteorological instrument used to measure the horizontal speed of wind. It uses a traditional three wind cups wind speed sensor structure that is highly durable.

  In addition, thanks to its smooth bearing system, it starts smoothly and ensures accurate data collection. The built-in signal processing unit in the cup can output the corresponding wind speed signal according to the user's demand, which can be widely used in the fields of meteorology, ocean, environment, airport, harbor, laboratory, industry and agriculture, and transportation.

What is a Wind Speed Sensor?

  wind speed sensors are devices designed to continually gauge both wind speed and wind volume (calculated as wind speed multiplied by the cross-sectional area). A prevalent type of wind speed sensor is the wind cup anemometer, believed to have been initially developed by Robinson. The measurement component consists of three or four hemispherical wind cups, evenly arranged and affixed in one direction on a rotating support fixed vertically to the ground.

What is a Wind Direction Sensor？

  Wind direction sensors are engineered instruments that determine the direction from which the wind is blowing. Utilizing technologies such as vane sensors and windsocks, they provide essential data for applications like weather forecasting and aviation.

How Does a Wind Speed Sensor Work?

  Wind speed sensors operate on principles such as cup anemometry. Picture small cups exposed to the wind—when they rotate, the sensor measures the rotational speed. This speed is then converted into electrical signals, offering accurate wind speed measurements.

How Does a Wind Direction Sensor Work?

  Wind direction sensors, often using vane technology, determine wind direction by measuring the orientation of a vane in relation to the incoming wind. This angular information is then translated into accurate directional data.

  The wind direction sensor detects and senses the wind direction information of the outside world by the rotation of the wind direction arrow, and transmits it to the coaxial code disk, and outputs a physical device corresponding to the wind direction related value; its main body adopts the mechanical structure of the wind vane, and when the wind blows towards the tail of the wind vane, the arrow of the wind vane will point to the direction of the wind blowing over. In order to maintain sensitivity to direction, different internal mechanisms are also used to give direction to the wind speed sensor.

How Does an Ultrasonic Wind Speed and Direction Sensor Work?

  The working principle of ultrasonic wind speed and direction sensor is to utilize ultrasonic time difference method to realize the measurement of wind speed and direction. As the sound propagation speed in the air, will be superimposed with the airflow speed in the direction of the wind. If the propagation direction of ultrasound is the same as the wind direction, then its speed will be accelerated; on the contrary, if the propagation direction of ultrasound if the opposite direction of the wind, then its speed will be slowed down. Therefore, under fixed detection conditions, the speed of ultrasonic wave propagation in the air can correspond to the wind speed function. The precise wind speed and direction can be obtained by calculation. Since the speed of the sound wave propagating in the air is greatly affected by the temperature; the wind speed sensor detects two opposite directions on two channels, so the effect of temperature on the speed of the sound wave is negligible.

Advantages:

Precision: Ultrasonic wind sensors provide highly accurate wind speed and direction measurements, minimizing errors in data collection.

Durability: With no moving parts, ultrasonic sensors experience less wear and tear, resulting in a longer lifespan.

Low Maintenance: The absence of mechanical components reduces maintenance needs, making ultrasonic sensors a cost-effective choice.

How to Install Wind Speed Sensors and Tips?

  Adopt flange mounting, threaded flange connection to make the wind speed sensor lower fittings firmly fixed in the flange, chassis Ø65mm, in the circumference of Ø47.1mm open four are Ø6mm mounting holes, the use of bolts will be tightly fixed in the bracket, so that the whole set of instruments, to maintain in the optimal level, to ensure that the accuracy of the wind data, the flange connection is easy to use, and can withstand the pressure of the larger.

Step 1: Choose an Optimal Location

Mount the sensor at a height above potential obstructions, such as trees or buildings.

Ensure the sensor is in an open area to capture unobstructed wind flow.

Step 2: Sensor Orientation

Align the sensor correctly with the prevailing wind direction.

Avoid placing it in the shadow of nearby structures that might cause turbulence.

Step 3: Secure Mounting

Utilize sturdy mounting hardware to secure the sensor in place.

Regularly check for any loose connections and tighten if necessary.

Step 4: Calibration

Follow the manufacturer's instructions for calibration.

Regularly calibrate the sensor to maintain accuracy.
