27106T Gill Propeller Anemometer
Once everything has been retrieved from the shipping carton, assemble the
27106T by doing the following:
1. Remove the propeller shaft from the Propeller Anemometer box
2. Remove the propeller from the Carbon Fiber Propeller box
3. Remove the nut that is on the top of the propeller shaft
4. Place the propeller onto the top of the propeller shaft
5. Replace the nut and tighten to secure the propeller to the shaft
6. Remove the dust cap from the cable’s connector and attach the cable to the
anemometer’s connector
3.2 Mounting to Crossarm
Tools Required:
• 5/32” Allen wrench for the NU-RAIL fitting or ½” open-end wrench for
CM220 Right Angle mount
• UV resistant cable ties
• small pair of diagonal-cutting pliers
• 6” to 10” torpedo level
This anemometer can be mounted to a CM200-series crossarm or a 019ALU
crossarm. The 1180’s pipe that ships with the 27106 mounts to a CM200
series crossarm via the CM220 (Figure 3-1) or 1049 NU-RAIL Fitting (Figures
3-2) or to the 019ALU’s NU-RAIL fitting (Figure 3-2).
When mounting the sensor to the crossarm, care should be taken to ensure that
there are no obstacles, or sensors, that will interfere with the vertical air flow
from either the up or down direction.
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.
