7. Installation

7.1 Siting

Locate wind sensors away from obstructions (e.g. trees and building). As a

general rule of thumb there should be a horizontal distance of at least ten times

the height of the obstruction between the windset and the obstruction. If it is

necessary to mount the sensors on the roof of a building, the height of the

sensors, above the roof, should be at least 1.5 times the height of the building.

See Section 9, References, for a list of references that discuss siting wind

direction sensors.
