Abstract (en)
[origin: WO2010049410A1] The invention relates to a method and to a thermal flow meter for determining at least one parameter that depends at least on the chemical composition of a measurement medium, wherein the measurement medium comprises n components, wherein the following applies: n is larger than or equal to two, wherein each mole fraction, volume fraction and/or mass fraction of m components of the measurement medium is measured, wherein the following applies: m is larger than or equal to n minus one, wherein the mole fractions, volume fractions and/or mass fractions of the k components of the measurement medium not measured, wherein the following applies: k is equal to n minus m, are established such that the sum of the mole fractions, volume fractions and/or mass fractions of the n components is equal to one.
