For the indirect identification of the mass flow of a specimen fluid stre the specimen fluid stream is mixed with a dilution fluid stream to form an total fluid stream that is to be investigated in view of specific constituents of the specimen fluid stream. The mass flow of a specimen fluid stream is identified from the difference between the measured mass flows of the dilution fluid stream and the total fluid stream. In order to reduce the possibilities of error in the setting of a defined dilution ration, the mass flows of the dilution fluid stream and the total fluid stream are calibrated relative to one another, to which end one of the calibration measurements is not undertaken at the respective fluid stream but is separately undertaken at the specimen fluid stream.
