Anemometers are used for measuring the speed of wind as well as the velocity and pressure of air, available in digital and manual forms. This instrument plays very important role in acquiring the direction and speed of the wind.
Importance of using anemometers
· To monitor the safety of high structures
· To control wind turbines
· Maneuvering ships
· Studying the wind effects
Weather stations use this tool, as the speed of wind helps indicating the change in weather patterns. To give an example, an approaching storm which is significant for pilots, climatologists and engineers.
The use of this tool
The built-in anemometers in large wind turbines are used for measuring the speed of wind, activating the brakes for stopping them to rotate when the wind blows very fast. Windsurfers or sailors use this tool to measure wind direction and speed, scientists used for monitoring conditions of the environment, in construction jobs it is used to monitor cranes.
Types of anemometer
· Thermal anemometer
It heats a fine wire to a particular temperature electrically and measures the temperature which is cooled by the air flow.
· Cup anemometer
This type of anemometer is quite simple yet very accurate, featuring a set of cups spinning on a mounted pole through the wind.
Other common types of anemometers are Propeller anemometer and sonic anemometer.
Note
Temperature humidity meter or sensor is used for sensing, measuring as well as reporting both air temperature and moisture.
