Abstract

A invenção refere-se a um método para medição da concentração de uma substância ou mistura de substâncias e/ou determinação do nível num fluido com fluorescência intrínseca, preferencialmente sistemas de combustível. A invenção refere-se ainda ao dispositivo ótico adequado para implementar o método, que compreende uma unidade onde se gera luz de excitação da amostra; uma unidade de deteção do sinal emitido pela amostra e uma unidade de processamento de sinal. O dispositivo e método por ele implementado permitem ainda determinar a distribuição espacial da substância ou mistura de substâncias líquidas e/ou o nível do fluido num reservatório. Uma das principais aplicações é a medição da concentração de oxigénio em tanques de combustível de aeronaves, baseada na medição da fluorescência intrínseca do combustível.
