Abstract
The present disclosure relates to a method for determining the methane index of a hydrocarbon-containing combustion gas mixture which has natural gas or biogas, having the steps: flowing the gas mixture through a measuring assembly; determining a first value of a first measurement variable related to a viscosity of the gas mixture; determining a second value of a second measurement variable related to a density of the gas mixture; determining a pressure value of the gas mixture, said pressure value belonging to the first value and the second value; determining a temperature value of the gas mixture, said temperature value belonging to the first value and the second value; and determining the methane index as a function of the first value, the second value, the pressure value, and the temperature value.
