SITING CONSIDERATIONS 

 
WARNING: Avoid overhead power lines whenever possible. If there are overhead power lines, use 
extreme care to prevent contact with the power lines while installing the equipment. NovaLynx 
recommends using only experienced equipment installers to avoid injury and serious problems. 
 
Choose a mounting location for the wind sensor that is free of obstructions since nearby objects can 
create eddy currents that will affect the wind measurements. Try to locate the wind sensor so that the 
nearest object is 10 x T away from the wind sensor mast, where T is the height of the object.  
 
Roof mounted sensors should be placed on the upwind side of the building and away from all exhaust 
vents. If the sensor is located on top of a building the sensor height should be 1.5 x H, where H is the 
height of the building.  
 
In all cases when the wind sensor data is to be correlated to National Weather Service data or World 
Meteorological Organization data, the standard exposure is 33 feet (10 meters) above the ground.

TAIL ASSEMBLY 

 

The tail piece must be assembled to the vane shaft before installing the sensor. Locate the tail piece 
(packed with this manual). Remove the blue tape from the shaft and save the two screws stored there. 
Slide the tail piece into the slot in the shaft and align the screw holes. Secure the tail with two screws 
using a #1 Phillips screwdriver.
