Abstract
Device for determining the mixing ratio of binary gases in a mixture thereof by measuring the velocity of sound in the gas mixture, the value of the velocity of sound in the gas mixture determined by the oscillating frequency of a fluidic oscillator, the absolute temperature (T.sub.r) of the gas mixture in the feedback means of the oscillator, a correction factor proportional to the difference between the absolute temperature (T.sub.r) and the predetermined temperature (T.sub.o).
