The ultrasonic anemometer arrived in today's mail.
I installed it and it appears to be working fine.
The mounting pole kit (#7717) that I used had a bit larger ID than the Radio Shack mast that I had on the tripod. I cut a slot with the Dremel to cinch it up tighter. That worked OK.
The aiming guide was a real help. I picked a landmark using Google Earth as an aiming point. (same direction that the vane/cup arm was pointed)
A chart showing this wind set is on my web site at:
http://rogerscityweather.com/wxDavisYoung.php#sonic. Depending on when you view the chart, the missing data from 1300-1400 was when it was being installed. Prior data was the standard VP2 wind set. Afterwards is using the ultrasonic one.
It is also viewable on the bulletin for WLL at:
Rogers City WLL if you have Pro.
Here is the plot via meteohub:
