Open Pan Evaporimeter- Engineering Lab Training Systems Description and Specifications for Lab Tenders
Open Pan Evaporimeter- Engineering Lab Training Systems.
The pan evaporimeter consists of a cylinderical reservoir of fixed
diameter and depth, filled with water to a few centimeters below the
rim. Afixed point gauge in a stilling wall serves to indicate the level
of water in the pan. A calibrated measuring cylinder is used to add or
remove water at each observation to bring the water level to the fixed
point. The reservoir is covered with wire mesh netting to protect the
pan from birds and animals. A thermometer suspended from a mount clamped
to the side of the reservoir records the temperature of the water in
the pan. Pan is made of copper sheet.
