Though basic in construction, the cup anemometer introduced in 1846 is considered an industry standard in measuring wind speed. Modern variants of this technology use three cups that spin around a vertical axis. The torque generated by the movement of wind is proportional to the wind speed. Cup anemometers must be calibrated because the torque also depends on the geometry of the cups used and the length of the arms they are attached to. Cup anemometers are relatively inexpensive and simple to construct, making them a popular project for science fairs.
Hot wire anemometers exploit the electrical properties of metals to indirectly measure wind speed. The electrical conductivity of a metal wire is proportional to the temperature of the metal. A hot wire anemometer is essentially a fine metal wire that is heated above ambient temperatures. When wind blows, the wire is cooled, measurably reducing its conductivity. The degree to which the conductivity is reduced is proportional to the velocity of the wind. Hot wire anemometers are small and require electrical measurement equipment to use effectively.

The speed of wind is measured with anemometers.
The instrument which is used to measure wind is a anemometer. This tool is used to determine the direction in which the wind is blowing.
No. The instrument used to measure wind speed is an anemometer.

Why weather tool is used to measure wind direction
Anemometers are used to measure wind speed.
To measure the direction of wind, a wind vane can be an ideal tool. A windsock can also be used to measure the direction and strength of the wind.
There are many ways to measure wind, but most common is Beaufort.
