Brief introduction FY-QC ultrasonic anemometers using high-frequency ultrasound to measure wind speed and direction , to solve the problem of the traditional mechanical wind measurements mechanical wear , no moving parts, the measurement accuracy is higher , more reliable performance . The ultrasonic probe can accurately measure the wind speed and direction . Weather station has four ultrasonic probe. Two probe a group, to send and receive from each other. In a calm environment, from each of the probe reached the other side of ultrasonic probe of time are the same; When there is wind, the wind reached the other side will affect the ultrasonic probe, probe by calculation between the ultrasonic transmission time, wind speed and direction at that time can be calculated. Stations having an internal microprocessor, by the four - probe measurement data to calculate the synthetic wind speed and direction . Sensors measure the air temperature in the whole process , to compensate for the change of the speed of sound in different temperatures .Ultrasonic weather station built-in temperature , humidity and pressure sensors can predict the weather change . To meet the growing need for real-time live weather information . You can also configure a variety of meteorological sensors needed is a compact instrument . Can be widely used in various fields of meteorology, hydrology, aviation , the environment , national defense and scientific research . Features 1. no moving parts, wear small; 2. little maintenance, long service life; 3. 316 stainless steel shell, salt fog; 4. using the ultrasonic probe of type, higher measurement accuracy; 5. probe heating, guarantee the normal work at low temperature; 6. quick response speed, using the acoustic phase compensation technique, high precision; 7. random error recognition technology, can guarantee low error measurement of wind, so that the output is more stable; 8. in the drizzle, measurement and compensation technology in foggy weather, environment adaptability has stronger; 9. digital filtering technology, immunity to electromagnetic interference.
