While anemometer is the correct term, these wind devices are also commonly called wind gauges or wind sensors. What Measures Wind Speed? In each case, the task is basically the same — to measure the wind. The instruments used to measure wind are known as anemometers and can record wind speed, direction and the strength of gusts. It also requires a lot of technical expertise to operate.Clearly, there’s a lot of ways to figure out wind speed. Ultrasonic The big drawback with what instrument measures wind speed here is that turbulence created by wind flowing around the instrument itself can distort the results. This device is made up of a ring of small cups that can be pushed by the wind, causing the cups to move in a circle.

If the air is rushing towards the measuring beam, the light waves reflecting off it are squeezed into a higher frequency. The normal unit of wind speed is the knot ( nautica l mile per hour = 0.51 m sec-1 = 1.15 mph ). Faster winds will cause the sound waves to compress into a higher frequency.
Some methods may not be that reliable.
On the other hand, this type of wind speed instrument is not that accurate.This system relies on the same idea behind the ultrasonic anemometer except that laser light is the one that measures wind speed. The arm is carried on a vertical spindle mounted on bearings which allow it to turn freely in the wind. This is referred to blue shifting.
Calibration corrections are applied to the measured wind speed.Wind direction is measured by a vane consisting of a thin horizontal arm carrying a vertical flat plate at one end with its edge to the wind and at the other end a balance weight which also serves as a pointer. A gale is defined as a surface wind of mean speed of 34-40 knots, averaged over a period of ten minutes. Originally, the device would measure wind speed by counting the number of cup rotations over a time interval.This technique was improved by the use of electronics for measuring purposes. One portion is used for reference while the other is aimed at the wind.
Mean wind over other averaging periods may also be calculated. . This instrument to measure wind speed is extremely accurate as well as very expensive.

The Mechanical anemometer, Pressure Tube anemometer, Thermal anemometer, Sound Wave anemometer and Doppler Laser Light anemometer.If you are interested in weather updates & want to know what measures wind speed then understanding wind speed is valuable. The wind blowing into the cups causes the spindle to rotate. Wind is measured by using the instrument called anemometer. Electrical components can either provide greater accuracy in counting rotations per time unit or act as a small generator that creates higher wattage as wind speed increases.The use of a fan permits wind direction to be simultaneously determined with a vane since the turbine has to be facing into the wind. Laser light bouncing off air particles headed away from the detector undergo red shifting to a lower frequency.The receiving station compares this reflected light to the reference beam to calculate the speed of the moving air. These anemometers are compact and very rugged. Measuring Wind Speed with an Anemometer and Arduino In this video we look at how to measure wind speed using an anemometer and Arduino.
The most common device used for wind speed measurement is called an anemometer. Liquid is placed at the bottom of the tube and wind blowing into the horizontal portion forces the liquid up along the vertical section.Modern versions have replaced the liquid with a flexible membrane that moves in response to the pressure differences while a gauge translates this into wind speed. *Amazon and the Amazon logo are trademarks of Amazon.com, Inc., or its affiliates. The instrument measures the speed of acoustic signals transmitted between two transducers located at the end of thin arms.
They operate by simply having the wind push on them. This approach will work on both ARM and AVR based Arduinos. The anemometer and wind vane are each attached to a horizontal supporting arm at the top of a 10 m mast (see image above).Where wind measurements are made in extreme weather conditions, such as on the top of mountains, a heated sonic anemometer is used (see above image) having no moving parts.
