An anemometer is a device used for measuring wind speed and direction.It is also a common weather station instrument. The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed instrument used in meteorology.The first known description of an anemometer was given by Leon Battista Alberti in 1450.
Having the anemometer 23' up meets NWS standards, 8' does not. Wind speed at low levels like 8' is reduced due to friction effects, variable terrain and wind shadowing from trees, bushes, buildings and so forth. For the most accurate report, you should mount the anemometer up high, if feasible.
We also offer seven versatile portable wind meters for a variety of applications. Visit the individual product page to learn more about our hand held anemometers. WeatherHawk hand-held wind meters float, are water resistant and have a two year warranty.

Apr 24, 2017· Anemometers are used to measure either wind speed or air pressure, depending on the style of anemometer. The most familiar form, the cup anemometer, was invented in 1846 by John Thomas Romney Robinson and features four hemispheric cups arranged at 90-degree angles. Making this form of anemometer is a common school ...
Nov 10, 2011· An anemometer looks like a weather vane, but instead of measuring which direction the wind is blowing with pointers, it has four cups so that it can more accurately measure wind speed.

An anemometer measures wind speed. Indoors, an anemometer measures air speed, air velocity or air flow. The air flow rate in buildings is often measured in cubic feet per minute (CFM) using anemometers to assess the performance of heating, ventilation and air conditioning (HVAC) systems and equipment.

An anemometer is an instrument used to measure the speed or velocity of gases either in a contained flow, such as airflow in a duct, or in unconfined flows, such as atmospheric wind. To determine the velocity, an anemometer detects change in some physical property of the fluid or the effect of the fluid on a mechanical device inserted into the flow.
