There are two distinct applications for an anemometer for wind turbines:
1. Predicting the potential wind available on a proposed wind farm
Before erecting a wind farm it is important to assess the amount of wind available over a prolonged period. Wind turbine sites are invariably financed on the basis of a return on investment, and this calculation requires extensive information on how much wind will be available all year round. Errors in this prediction can have an enormous effect on the amount of electricity produced and the viability of the investment.

Large towers are often erected with many anemometers mounted at varying heights to collect data. It is important that the correct anemometers are selected at this time, as the data produced by the survey must be accurate and comprehensive in order to accurately asses the site.
For this type of application, the Gill WindMaster range of anemometers is often used. The three axis nature of the WindMaster makes it ideal for monitoring turbulent flows, with data provided for wind speed, wind direction and Sonic Temperature.

2. Wind Turbine Control
 Wind turbines need to be steered into the wind, with the blades controlled according to the wind strength to ensure maximum efficiency. To achieve this, an anemometer is placed at the top of each wind turbine, forming a key control function for the wind turbine. As Wind farms are often situated in remote on-shore and off-shore locations, it is important to select an anemometer for the wind turbine that will be accurate and reliable, with little to no maintenance required.
The Gill Extreme Weather WindObserver anemometer for wind turbines has been designed specifically for this type of use. This anemometer for wind turbines is designed to remain ice free in most freezing weather conditions, with a robust stainless-steel construction and the ability to monitor wind speeds up to 75m/s (0-168mph).
