Digital measurement of evaporation based on oversampling technique

Abstract

This article describes a system which performs a measurement task by controlling water level in an evaporation measuring setup. This measurement is inherently digital and the intelligent controller performs noise reduction and disturbance compensation. This measurement is based on oversampling for better noise shaping and increase in measurement accuracy. The proposed structure is implemented and the experimental results are satisfactory in terms of accuracy of measurement, according to the need in hydrological studies.
