APPLICATION OF OSENON ULTRASONIC WIND SENSOR

 

The working principle of the ultrasonic wind speed and direction instrument is to use the ultrasonic time difference method to measure the wind speed. The speed at which sound travels in the air is superimposed on the speed of the airflow. If the ultrasonic wave travels in the same direction as the wind direction, its speed will increase. Conversely, if the ultrasonic wave travels in the opposite direction to the wind direction, its speed will be slower. Therefore, under fixed detection conditions, the speed at which ultrasonic waves propagate in the air can correspond to the wind speed function. Accurate wind speed and direction can be obtained by calculation. Since sound waves propagate in the air, its velocity is greatly affected by temperature; this anemometer detects two opposite directions on the two channels, so the effect of temperature on the speed of sound waves is negligible.

Precautions for use:


Considering the accuracy and representativeness of the measurement data, the following problems need to be noted when using an ultrasonic windometer.
(1) In order to improve the representativeness of the measurement results of the wind measurement instrument, considering the influence of terrain and obstacles on the wind speed measurement, it is generally required that the wind gauge should be installed at an open area of 10 m, that is, the distance between the wind measurement instrument and the obstacle. Must be at least 10 times higher than the height of the wind instrument.
(2) In order to improve the time representative of the results of the wind turbine profit margin, the values measured over a period of time are averaged.
(3) In order to make the cross-winding measurement results comparative, it is necessary to use a test instrument of a uniform type.
(4) The mechanical and aerodynamic characteristics of the crosswind instrument must be taken into consideration when selecting the wind instrument. Mechanical construction characteristics refer to accuracy, sensitivity, resolution, starting wind speed, range, and so on. Aerodynamic characteristics refer to damping ratio, time constant, distance constant, inertia, etc.
