Abstract (en)

[origin: DE19749524A1] The invention relates to a device for measuring the volumetric flow of air, comprising two temperature-dependent resistances which are fed by power sources and whose resistance values are used to measure mass and temperature. A read-out signal proportional to the volume of air is created by multiplying both signals and linearizing the result.
