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.
