A new evaporation measurement system for the class "A" pan

Abstract

The present work deals with design, construction and performance analysis of a new system for evaporimetric measurements, which is coupled to a standard class A evaporation pan, and which is called "Modified Class A Pan". The viability of the system was checked against simultaneous measurements taken with the conventional system (standard class A pan plus micrometer depth gauge), indicating, from statistical tests, that minimizing errors can be made even by qualified staff, and making it possible to carry out evaporimetric measurements with good approximation on rainy days.
