processo para monitorar a qualidade de um combustível contendo álcool em um tanque de armazenamento.

摘要

The method involves measuring the density of fluid contained in a marsh area (8) of a storage tank (1). The measured density is compared with a predetermined value. The density of a mixed phase containing water and alcohol is characterized as a function of the composition. The composition of the alcohol-containing fuel above the marsh area is estimated from the comparison between the measured densities of the liquid in the bottom area with the given values.
