Anemometer installation on roof of Deconism Gallery, using three size 6, schedule 40 pipes in their original uncut 20 foot lengths. The wire (4 conductors running inside a shield) runs along the rightmost leg of the 3 legged "tripod" mount that's attached to the rigging that runs around the perimeter of the roof.
An anemometer is a device for measuring wind speed, and is one of the instruments found in a weather station. Anemometer comes from the latin word 'Anemos', meaning wind. The familiar cup-anemometer was invented in 1846 by John Thomas Romney Robinson.
Anemometers, such as the one shown below, at Deconism Gallery, are often used in conjunction with windmills, so that the wind speed and power generated by the turbine (windmill) can be logged together in a data logger.
Other types of anemometers include:
- hot wire or hot plate sensors, which measure the cooling of a heated element immersed in the wind
- ultrasonic sensors, which measure the Doppler shift of sound waves travelling across the moving air.
