260-953 Alter-Type Wind Screen for Tipping Bucket Rain Gages
3. Installation
The tipping bucket rain gage is typically installed before the wind screen (refer
to the rain gage’s manual for installation procedures).
3.1 Site Considerations
The foundation size must be at least 4 ft x 4 ft if the same concrete or wooden
foundation is used for both the wind screen and tipping bucket rain gage (see
Figure 3-1). A larger area may be desirable to more easily access the wind
screen and tipping bucket rain gage.
FIGURE 3-1. Foundation size and post placement
Sites where there is open ground between the wind screen and the rain gage
should be cleared of weeds or grass. A gravel path is recommended to permit
access to the rain gage during wet conditions.
3.2 Ring Assembly
On each ring quadrant, alternate the wind screen leaves and spacers as shown
in Figure 3-2. The leaves should be installed so that the flat sides of the leaves
will face the rain gage.
The wind screen leaves have very sharp edges. Use
leather gloves while handling the leaves, and avoid
brushing against them. CAUTION
