Windmill Anemometer: It is the type of anemometer which is used to measure both speeds of the wind and its direction. It is used for air conditioning purposes, heating, and ventilating. Hot Wire Anemometer: It is the type of anemometer which is used to measure both speeds of the wind and pressure. It is used by educational institutions, research labs, and meteorologists. The wind speed is mainly based on the speed at which the cup rotates. When the cup is hit by the wind it starts to rotate. Cup Anemometer: It is the type of anemometer that has cups placed on its vertical axis. There are several types of anemometerbut we’ll get to know about five of its types: While the number of rotations made by an anemometer helps in calculating the relative speed of the wind. When the wind starts to blow the cup starts to rotate making its vertical rode rotate as fast as the wind is blowing. It has four or three cups that rotate when the wind starts to flow, they are connected to arms that are attached to a vertical rod up at a height by a pole. The working principle of an anemometer is quite simple and there has been no change since 1846. The diagram below shows a typical setup in an anemometer device: Anemometer Working Principle It was discovered by Leon Battista Alberti in 1450. The origin of its word comes from the Greek word anemos which means wind. It is generally used as a weather station device by weather forecasting stations to tell about the current weather and predict the upcoming weather of an area. It also helps in knowing the direction of the wind and measuring the pressure of the wind. AnemometerĪn Anemometeris a device that is used to calculate the speed and velocity of the wind. So read on to know more about its working principle, types, steps to make it, and uses along with some FAQs. 
In this article, we will be learning everything about an anemometer.
