The first photo shows where my CURRENT anemometer is placed. It is a LaCrosse (bad idea) and I will be returning it back to Costco because it is NOT an accurate weather station. I have since bought a Davis VP2
Getting back to the location, in the photo you can see that the trees can cause inaccurate readings:
Here is where I want to place the VP2 anemometer. It is on the roof of a 2 story home. So it will be around 30-40 feet from the ground. I was going to use a rigid PVC pipe and attach that to one of the roof vents that are visible in the photo:
My questions are as follows:
1 - How much wind load/resistance will their be with the anemometer attached to a round PVC pipe, sitting on top of a roof?
2 - Running the 40 foot cable from the anemometer down to where the other sensors will be, does the cable need to be tucked under the tiles, exposed, or run through conduit? How exposed can it be? Especially with the intense UV light in Phx, AZ and sitting on a hot roof.
3 - Or should I just mount the anemometer back at the same wood post location I had the LaCrosse anemometer in picture #1?
