摘要
A for determining and/or monitoring aggregate state changes on a thermal, flow measuring device of at least a first part of a measured medium, wherein, by means of the temperature of the medium being measured, by means of the chemical composition of the medium being measured and by means of the partial pressure of the at least first part of the medium being measured and/or by means of the total pressure of the medium being measured, at least one phase boundary line of the at least first part of the medium being measured is ascertained At least a first measurement signal is provided from a temperature difference between a first temperature sensor and a second temperature sensor of the thermal, flow measuring device and/or from a heating power supplied the medium being measured, wherein, in the case of a state of the at least first part of the medium being measured in the region of the phase boundary line of the first part of the medium being measured, disturbances of predetermined type in the measurement signal are detected as aggregate state changes on the thermal flow device of the at least first part of the medium being measured.
