7. Installation
7.1 Siting
Locate wind sensors away from obstructions (for example, trees and building).
Generally, there should be a horizontal distance of at least ten times the height
of the obstruction between the windset and the obstruction. If the sensors need
to be mounted on a roof, the height of the sensors above the roof, should be at
least 1.5 times the height of the building. See Section 10, References, for a list
of references that discuss siting wind speed and direction sensors.
7.2 Assembly and Mounting
Tools Required:
• 5/64 inch Allen wrench
• 1/2 inch open end wrench
• compass and declination angle for the site (see Appendix A)
• small screw driver provided with datalogger
• UV resistant cable ties
• small pair of diagonal-cutting pliers
• 6 – 10 inch torpedo level
Install the propeller to its shaft using the nut provided with the sensor.
The Wind Monitor mounts to a standard 1 inch IPS schedule 40 pipe (1.31 inch
O.D.). A 12 inch long mounting pipe ships with the Wind Monitor for
attaching the sensor to a CM200-series crossarm with the CM220 (FIGURE
7-1) or 1049 Nurail® fitting (FIGURE 4-1 in Quickstart section). The 05103
can also be mounted to a CM110 series tripod mast with the CM216 Mast
Mounting Kit (see FIGURE 7-2).
Mount the CM200-series crossarm to the tripod or tower. Orient the crossarm
North-South, with the 1 inch Nurail® or CM220 on the North end. Appendix
A contains detailed information on determining true north using a compass and
the magnetic declination for the site.
Secure the mounting pipe to the Nurail® or CM220. Place the orientation ring,
followed by the Wind Monitor on the mounting pipe. Orient the junction box
to the south, and tighten the band clamps on the orientation ring and mounting
post. Final sensor orientation is done after the datalogger has been
programmed to measure wind direction as described in Appendix A.
Route the sensor cable along the underside of the crossarm to the tower/tripod
mast, and to the instrument enclosure. Secure the sensor cable to the crossarm
and mast using cable ties.
