Abstract

MÉTODO DE DETECTAR UMA CONCENTRAÇçO DE ÁLCOOL EM UM LÍQUIDO MISTURADO E APARELHO DETECTOR DE CONCENTRAÇçO DE ÁLCOOL. Na detecção de uma concentração de álcool, uma primeira luz e uma segunda luz são irradiadas para um líquido misturado incluindo um combustível fóssil, um álcool e água, e a concentração de álcool é calculada com base em quantidades da primeira luz e segunda luz permeadas através do líquido misturado. Na detecção, uma diferença de uma transmitância do combustível fóssil com respeito à primeira luz e cada ta do álcool e água com respeito à primeira luz é maior do que um primeiro valor. Em adição, uma diferença de uma transmitância de água com respeito à segunda luz e cada transmitância do combustível fóssil e do álcool com respeito à segunda luz é maior do que um segundo valor.METHOD OF DETECTING ALCOHOL CONCENTRATION IN A MIXED LIQUID AND ALCOHOL CONCENTRATION DETECTOR. On detection of an alcohol concentration, a first light and a second light are irradiated to a mixed liquid including a fossil fuel, an alcohol and water, and the alcohol concentration is calculated based on amounts of the first light and second light permeated through of the mixed liquid. In detection, a difference of a fossil fuel transmittance with respect to the first light and each of the alcohol and water with respect to the first light is greater than a first value. In addition, a difference in water transmittance with respect to the second light and each fossil fuel and alcohol transmittance with respect to the second light is greater than a second value.
