Rain collector position
« on: February 25, 2009, 02:08:04 AM »
Does it really matter if the rain collector is roof top?  The manual says it should be no more than 3 ft off the ground. Can you pole mount the rain collector?  How? Is there an optional mounting bracket or something to keep it level?

I have mine pole mounted, using a "Rain Collector Tray " purchased from Ambient.  You level it out, by adding washers under the appropriate leg of the unit.  You can see them in a couple of my photos.

The higher the collector is off the ground, the more it is subject to wind currents/eddies that will influence the "catch" of the gauge. In addition, a gauge located at the preferred height is easier to maintain as it does require occasional cleaning. An excellent guide to siting rain and other gauges can be found in the following pdf file:

6 ft off the ground will work too.

Then again, you don't want the rain catchment too low either. Yellow rain is very confounding.  :-P

Is the WMR200a tempature and humidity sensors considered shielded?  Does it need a shield or is the housing sufficient? Must the humidity sensor be at ground level to achieve accurate results?  I wonder why and manufacturer would design a pole to hold all the sensors if they really should be located in different areas.
