3D Ultrasonic Anemometer

3D Ultrasonic Anemometer Product Description

3D Ultrasonic Anemometer adopts advanced ultrasonic measurement technology and unique structural design, which greatly reduces the influence of wind resistance and improves the accuracy of measurement. All-metal material, without any moving parts, sturdy and durable, can simultaneously measure the horizontal and vertical wind direction, X/Y/Z-axis wind speed (i.e. U, V, W vector output). It is adaptable to all-weather operation in various environments, providing reliable data for meteorological monitoring in various fields. Widely used in urban environment monitoring, wind power generation, meteorological monitoring, bridges and tunnels, sailing ships, aviation airports and other fields.

 3D Ultrasonic Anemometer working principle

The distance between three pairs of ultrasonic transducers is fixed, the transducer transceiver circuit is controlled to realize that multiple pairs of transducers emit and receive ultrasonic waves sequentially, the ultrasonic flight time is measured in downwind and upwind, and the wind speed components in three directions are obtained through the relationship between the wind speed and the flight time, and the total wind speed is obtained from the vector synthesis principle. According to the wind speed component in the horizontal plane to find out the horizontal wind direction, vertical wind speed component to find out the vertical wind direction.

3D Ultrasonic Anemometer wiring method 

(1) If you are equipped with the collector produced by our company, you can directly use the sensor cable to connect the sensor with the corresponding interface on the collector.

(2) If the sensor is purchased separately, the sensor wiring is defined as follows: 

 Note: The wiring label on the communication cable shall prevail.

Installation of three-dimensional ultrasonic wind speed and wind direction meter Notes

Ultrasonic wind speed sensor can meet a number of specifications, can be used in different environments around the world, the field does not need to carry out complex maintenance and calibration.

Ø Mount at the top of the column if possible;

Ø recommends a mounting height of at least 2 meters above the ground;

Ø The area around the sensor should be empty and free of obstructions.

Ø Ensure that the device is powered by a continuous power supply during operation;

Ø Avoid flotsam from surrounding buildings such as trees, utility poles, tall buildings, etc. These can have an effect on the accuracy of the ultrasonic wind speed and direction meter.

The World Meteorological Organization gives the following advice:

Ø Installation criteria for weather meters: 10 meters above ground level in open areas; open areas are defined as 10 meters above the height of any obstacle to the weather meter;

Ø If mounted on a building, the meteorological instrument mounting height should theoretically be 1.5 times the height of the building;

Ø if mounted on a boom on a mast, a tower or a branch of a mast, the length of the boom or branch must be twice the minimum diameter or diagonal of the tower. The boom needs to be installed on the side of the prevailing wind; 

3D Ultrasonic Anemometer Installation method 

Positioning: The top of the anemometer is labeled with an indicator mark which corresponds to the 0° phase of the instrument, using this as a starting point in clockwise increments of 0 to 360°. In order to ensure that the instrument is installed correctly, before fixing the instrument, it is necessary to use a precision direction measuring instrument to determine a fixed direction as a reference, based on this direction to determine the installation orientation. (Usually choose to point to the north installation).

Mounting: The device can be fixed to the mounting bracket with 4 stainless steel bolts and nuts. The aviation plug is connected to the connector on the bottom of the unit. When the plug is connected, turn the outer sleeve clockwise to lock the plug. The user must properly strain relief the cables.

NOTE: The customer must ensure that the unit is installed in an open area so that surrounding buildings do not create obstructions to airflow or cause flocculation. Do not install the unit next to radar or radio transmitters.

NOTE: Our company is in a constant state of discovery and research and development and we reserve the right to make improvements in performance and design without prior notice.
