Advantages of ultrasonic wind speed and direction meters over mechanical ones

At present, the ultrasonic wind speed and direction meter has become a relatively advanced wind speed and direction measuring instrument. Because it can better overcome the inherent shortcomings of the mechanical wind speed and direction meter, so that it can be all-weather long time normal operation and increasingly adopted by people. It will become a powerful alternative to mechanical anemometers.

Traditional mechanical anemometers have rotating parts and are prone to wear and tear. The mechanical structure may be damaged in bad weather, sand, dust, salt spray, etc. will also erode the mechanical structure. At the same time, mechanical anemometers have a starting wind speed due to friction, which is less than the starting value and cannot drive the propeller or wind cup. Therefore, breezes below the starting wind speed cannot be measured with a mechanical anemometer. But an ultrasonic anemometer is completely! No! No problems in this respect!

It has no moving mechanical parts and is replaced by several ultrasonic sensors. The lower limit of the theoretical wind speed range is 0, with no starting wind speed; the upper limit of the wind speed can be varied with the sensor spacing.
