Abstract

In this paper, an optical fiber device based on long period grating is applied as refractive index transducer to measure the ethanol concentration in ethanol-gasoline blends. The device metrological characteristics - response curve, sensitivity, resolution, conformity, repeatability, combined uncertainty and expanded uncertainty - were determined and compared with characteristics associated with an Abbe refractometer. For ethanol concentration ranging from 20% to 40%, the LPG combined uncertainty was 0.70% and the expanded uncertainty was 1.70 %.
