The present invention relates to a device and a method for determining mixing ratios of flowing media, in particular for determining the mixing ratios of two gases by using two flow resistances with different characteristic curves.
The determination of the percentages of different components of fluids, for instance gas or liquid mixtures is necessary in many fields of engineering. For this purpose there exist a large variety of different methods using optical, acoustic, or electrochemical methods. Nonetheless, there is lacking a simple method for determining the mixing ratios of two fluids, in particular of two gases. Subject matter of the present invention is therefore a simple method for determining the relative portions of two components of a fluid mixture, in particular of a gas mixture, and a device suitable therefor.
Thus, the present invention teaches a device according to claim 1 and a method according to claim 6 carried out by means of said device. Advantageous embodiments of the invention are subject matter of subclaims referred thereto.
