Looking at the schematic diagram of an anemometer, we will notice that a popular anemometer is composed of 3 (or 4) solid cups that are soldered to the rigid metal arms, and attached horizontally to the skeleton. With the wind blowing, the main skeleton spins due to the coupling effect produced within the instrument. The more the speed of the wind flow, the greater the angular velocity (or simply the spin) of the skeleton rod. In practice, an anemometer is devised to calculate the number of spins per unit of time. As you’d have often realized, the wind speed keeps fluctuating and so to ensure accuracy and precision in measurement, the wind speed is always measured for only a short time.
An industry-trending anemometer like the HTC AVM-08 Hot wire Anemometer can detect wind speeds with the following specifications|

Make sure you buy from a genuine dealer to avoid getting inferior or way too costly products. This instrument can be used both for your commercial as well as your personal usage. Some of the other common anemometers are:
● Sonic Anemometers: To measure the directional speed of the ultrasonic waves (in 1, 2, and 3 dimensions).
Consisting of powerful transducers, sonic anemometers are sensitive to even slight velocity fluctuations, thus making this device a hot pick for scientific and meteorological studies.
- Plate Anemometers: Having a surface (instead of hollow cups) circular or square, the main body is balanced on a spring.
Since they cannot detect smaller wind pressures or the speed for that matter, they can be quite useful in recording the average wind pressures.
