What is the working principle of ultrasonic anemometer?
What is the working principle of JD-WQX12 ultrasonic anemometer? The working principle is to use the ultrasonic time-of-flight method to measure the wind speed. The velocity of sound in the air is superimposed on the velocity of the airflow in the wind direction. If the ultrasonic wave travels in the same direction as the wind, its speed will increase; otherwise, its speed will slow down. Wind direction anemometer is a modern environmental meteorological instrument developed mainly for measuring wind direction and wind speed. We know that the size of the anemometer will not only have a certain impact on people's daily travel, but also have a great impact on agricultural planting. In the current weather, it is very important to judge the formation, evolution and movement process of the weather system by using the wind direction and wind speed, and it plays a very important role in mastering the whole weather.
Ultrasonic anemometer
The JD-WQX12 twelve-element micro-weather instrument, also known as the air pollution environment monitor, is developed by Shandong Jingdao Photoelectric Technology Co., Ltd. for PM2.5, PM10, CO, SO2, NO2, O3 in response to the increasingly severe environmental protection situation. A highly integrated instrument for monitoring six pollutant parameters and a total of 12 parameters including air temperature, relative humidity, wind speed, wind direction, atmospheric pressure and rainfall. The function is mainly to conduct 24-hour continuous online monitoring of conventional pollution factors and meteorological auxiliary parameters in the air, and provide the analyzed data to the Environmental Protection Bureau as a reference for air quality and to assist environmental protection decision-making. In addition, hydrogen sulfide, volatile organic pollutants, sunlight radiation, noise, etc. are optional.
