Abstract
The present disclosure relates to sensors and the teachings may be applied to a method and a corresponding apparatus for determining a concentration of a constituent of a fluid mixture in a fluid chamber. A method may include sending and receiving a first sound signal; sending and receiving a second sound signal; measuring the propagation time of the sound signals; calculating a value based on the propagation times representative of the concentration; sending and receiving a third sound signal with a second sound conversion unit; measuring a third propagation time; and calculating a second characteristic value based on the first propagation time and the third propagation time, representative of a mass flow of the fluid mixture.
