6.1 Unpacking
Carefully unpack all of the evaporation ga
u
ge. Remove the top cover. The
float with chain and counter-weight are shipped inside the bottom of the
ga
u
ge housing. Remove packing material from inside the housing. The float
cannot be removed without removing the pot/gear assembly housing.
Carefully remove the packing materials and parts from
inside the ga
u
ge, and avoid hitting the potentiometer
sprocket wheel.
6.2 Siting
The site should be level and free of nearby obstructions that can cast shadows
or reflect sunlight onto the evaporation pan. To avoid shadows or reflection,
the evaporation ga
u
ge should be north of the evaporation pan. Placing the
ga
u
ge away from the pan also helps reduce shadows and reflections.
The evaporation pan should sit upon a level wooden platform that is placed
over soil typical of the area. Dimensions of the platform need to be 127 x 127 x
