Abstract
A method for determining properties of a hydrocarbon containing gas mixture, especially natural gas or biogas, comprising: allowing the gas mixture to flow through a measuring arrangement; determining a pressure- and temperature dependent viscosity measured value, an associated measured value of temperature and an associated pressure measured value of the flowing gas mixture; ascertaining a first value of a first variable, which characterizes the energy content of the flowing gas mixture, based on viscosity measured value, the associated measured value of temperature, and the associated pressure measured value, wherein the first variable characterizing the energy content is the Wobbe index or the calorific value of the flowing gas mixture, wherein the Wobbe index is preferable.
