7. Installation
7.1 Siting
Locate wind sensors away from obstructions such as trees or buildings.
Generally, there should be a horizontal distance of at least ten times the height
of the obstruction between the Wind Monitor 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
(p. 15)
, 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
(p. C-1)
•
Small screw driver provided with datalogger
•
UV resistant cable ties
•
Small pair of diagonal-cutting pliers
•
6 to 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
) or 1049
NU-RAIL® fitting (FIGURE
in QuickStart section). The 05103 can also
be mounted to a CM110 series tripod mast with the CM216 Mast Mounting Kit
Mount the CM200-series crossarm to the tripod or tower. Orient the crossarm
North-South, with the 1 inch NU-RAIL® or CM220 on the North end.
Wind Direction Sensor Orientation
(p. C-1)
, contains detailed
information on determining true north using a compass and the magnetic
declination for the site.
Secure the mounting pipe to the NU-RAIL® 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
(p. C-1)
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.
