ABSTRACT:
An evaporimeter formed of a capillary tube hydraulically coupled to a sheet of filter paper to form a capillary system establishing hydraulic continuity of liquid between the tube and the surface of the filter paper is automatically replenished with the liquid as the liquid evaporates. The rate of evaporation from the surface of the filter paper of a liquid, such as water, in the tube and filter paper is automatically measured using a photoelectric sensor as the air-liquid interface moves upwardly in the tube as the water is drawn from the tube to replace the evaporated water.
