Actually, anemometers can be categorized into two categories such as portable handheld anemometers and those affixed to the ground at weather stations.
There are many types of anemometers to measure wind speed.
In this way, wind speed will be expressed in rpm. Multiply it by two to get revolutions or rotations per minute. Then, count the number of times the cup with the red mark passes in front of in the 30 seconds. To measure the wind speed, take the anemometer outside and measure the wind speed. At the present time, modern anemometers have the unique look and even other pocket-size devices. Wind speed measurements help in weather forecasting like hurricanes, storms, and tornadoes. Its revolutions per minute will give the wind speed in rpm unit. Obviously, the faster the wind, the faster the cups spin the axis. Each of these four is attached to the horizontal arm. In this case of traditional anemometer has four cups to measure the speed of the wind. Actually, the wind is moving the air in motion and hence it is causing the difference in air pressure. This device is mostly found in the weather stations. Many times these are also important to the work of physicists, who study the way air moves. Further, it is useful to calculate wind speed. Actually, the anemometer counts the number of rotations. Sometimes to measure the effect of the fluid on a mechanical device inserted into the flow. To determine the air velocity, anemometers are able to detect the change in some physical properties of the fluid. It may be either in a contained flow like airflow in a duct or in the unconfined flows like the atmospheric wind. The anemometer is a mechanical instrument useful to measure the speed or velocity of air or gases. 2 FAQs about Anemometers Introduction to the Anemometer
