Abstract
The present disclosure relates to a method for determining a volumetric and/or mass flow rate of a medium flowing in a tube, wherein a density and/or a viscosity of the fluid is/are determined using a MEMS sensor chip, wherein the medium flowing in the tube at least partially flows through a measuring channel of the MEMS sensor chip to determine the density and/or the viscosity of the fluid, and wherein the volumetric and/or mass flow rate of the medium is determined regardless of the medium based on a detected pressure drop over the measuring channel of the MEMS sensor chip and the density and/or viscosity determined by the MEMS sensor.
