Abstract (en)

[origin: WO2015185185A1] Disclosed is a method for determining the volumetric flow rate of a fluid medium through a measuring section in a substantially gas-type independent manner, said method comprising the following steps: pulsed heating of the medium by means of a heating element; recording a first time at which a maximum temperature occurs at a first temperature sensor lying upstream or downstream from, and adjacent to, the heating element; recording a second time at which a maximum temperature occurs at a second temperature sensor lying downstream of the heating element, wherein the second temperature sensor is located further away from the heat source than the first temperature sensor; calculating a time difference between the first and the second time; and determining the volumetric flow rate on the basis of the time difference.
