2. 2 UT10 Tower Installation
The UT10 10-ft tower provides a support structure for mounting the
weather station components. Figure 2. 2-1 shows a typical UT10 equipped
with instrumentation enclosure, meteorological sensors, and solar panel.
2. 2.1 Base Installation
The UT10 tower attaches to a user supplied concrete foundation as shown in
Figure 2.
2-2. The tilt base, anchor bolts, and nuts are included with the tower.
1. Dig a hole 24" square and 24" deep. Lighter soils will require a deeper
hole.
2. Construct a concrete form out of 2" x 4" lumber 24" square (inside
dimensions). Center the form over the hole and drive a stake centered
along the outside edge of each side. Level the form by driving nails
through the stakes and into the form while holding the form level.
3. Assemble the anchor bolts and tilt base as shown in Figure 2. 2-3. There
should be two nuts below the base and one nut above.
4. Fill the hole and form with concrete. Screed the concrete level with the
top of the form. Allow the concrete to setup enough to support the weight
of the base*, then position the base (with the anchor bolts attached) over
the center of the concrete foundation and press the anchor bolts into the
concrete as shown in Figure 2.
2-3. The bottom of the threads should be
approximately 1/2" above the concrete. Level the base in both directions
using a small level.
*Rather than relying on the concrete to support the base, two boards 1" to
1.5" thick that span the forms can be positioned under the base while the
concrete hardens.
5. Remove the form after the concrete has sufficiently hardened. Level the
base by adjusting the two lower nuts. Minor adjustments will be required
after the tower is attached.
