Abstract

A binary gas-mixture composition sensor is described using the dependence of the velocity of sound in a gas on its molecular weight and an adiabatic index using an acoustic resonator. For analysis of the mixture composition, one of the gases must be available in a pure form. In this case, the measurement error is no worse than 10–4. A mixture with a known composition can also be used as a reference one.
