Abstract
The invention concerns a mass flow meter comprising at least a resistive wire (1 or 2) placed in the path of a fluid whereof the flow rate is to be measured, means (30) for applying to the wire current pulses, measuring means for determining the cooling speed of the wire between said pulses. The invention is characterised in that it comprises means for determining, on the basis of at least one measurement of the cooling speed, the type of fluid on the path of which the resistive wire is arranged.
