The Ultrasonic Sensor is designed for measuring the evaporation level in an evaporation pan type "Class A". The instrument can be used by the agricultural research institutes to determine the individual water requirements of plants, and for fields’ irrigations. The instrument is equipped with temperature compensation for the optimal operation.

The EP-Class A Evaporation Pan is a standard tool for the measurement of water evaporation. It can be installed on a wooden platform set on the ground in a grassy location. The pan is filled up to 60 mm from the top and exposed to represent an
open body of water. The pan is filled within 60mm from the top. The water level can be maintained with a programmable Evaporation Pan Auto-Fill valve.
