Ultrasonic analyzers of ethanol in automotive gasoline are reviewed. These devices allow determination of the volume fraction of ethanol in ethanol-gasoline mixtures in the range from 0 to 100 %. The relative error of measurement of 5 % volume fraction of ethanol is 0.107–0.427 %, and the relative error of measurement of 100 % volume fraction of ethanol is 0.005–0.021 %. Analysis time is several milliseconds.
