About Evaporation
Evaporation gages determine the evaporation rate by measuring the changing water level in an evaporation pan. They consist of a float, pulley, and counterweight attached to a potentiometer mounted through a gear assembly in a weatherproof housing. The potentiometer produces
a resistance output proportional to the position of the float.
