Determines
the evaporation rate by measuring changing
water level in an evaporation pan. The gauge
is intended for use with a National Weather
Service, class A pan.
The instrument consists of a fl oat, chain,
and counterweight attached to a precision
1000-ohm potentiometer mounted through a
sprocket assembly in a weatherproof housing.
The triangular base plate is equipped with
three leveling screws and a bubble level
indicator. The potentiometer produces a
resistance output proportional to the position
of the float which can be monitored on site
using a data logger or monitored remotely
by telemetry equipment.
