These switches comprise flexible metal reeds which are included in a glass enclosure. This magnet passes through a sensor, which is known as a reed switch. When these arms spin, they drive a shaft with a magnet attached to its end. The arms will spin faster at fast wind speeds. These cups can easily catch winds and spin the arms in the direction of the wind. The cups are located at the end of each arm. These devices feature four hemispherical cups mounted on a vertical shaft. They are commonly found in weather forecasting stations and above buildings. Cup Anemometers: These are the simplest type of velocity anemometers used today.Have a look at Triplett Thermo Anemometer Product Range –ġ0-in-1 Environmental Meter with Air Flow - (EM300)Ĥ" (100mm) Large Vane CFM/CMM Thermo-Anemometer (CFM400) Vane anemometers can be availed in large sizes where they are installed above the building or can be availed in pocket-sized designs, which can be fit into your bags or pockets. Like acup anemometer, the wind speed reading is taken by analyzing the impulse frequencies. This rotation is captured by the small field sensor near the magnet, and it passes the electric impulses to the processor of the device. When the propeller spins, the magnet rotates on its own. The propeller has a magnet located at its center. The vane anemometer features a tail and a propeller on the same axis. Propellers or Vane Anemometers: These anemometers are designed such that their axis lies parallel to the wind direction, which is why they operate horizontally.The following are a few common types of anemometers, which although designed for effective wind measurement, differ in terms of their measurement techniques. The velocity anemometers are distinguished into more types based on their designs and operating principles. This section focuses mainly on how the velocity of wind is measured using different velocity anemometers.

How to Measure Wind Speed Using an Anemometer in Weather Station?īased on their application, anemometers are distinguished into two types – velocity anemometers and pressure anemometers. Anemometer are also used in HVAC units for measuring the airflow! How this instrument works in both scenarios? This post offers answer to the same and more. These wind speed measuring devices offer valuable information for weather forecasting, which may be useful for farmers, pilots, weather forecasting officials, and more. Invented in 1450 by Alberti, the designs of anemometers have evolved over the years, as it has emerged as an important instrument used to measure wind speed/velocity and wind pressure. This behavior is analyzed using instruments such as anemometers. Wind behavior is one of the important aspects of weather forecasting because it can predict the onset of storms or windy day.
