description The invention relates to a method for determining a flow rate of a fluid (1) independent of the physical properties of the fluid comprising: - placing a thermal flow sensor (2) in thermal contact with a fluid flow (3); - measuring flow rate; - placing a thermal property sensor (4) in a measurement cavity (5) in fluidic contact with, and preferably adjacent to, the fluid flow; - receiving a portion (6) of the fluid in the measurement cavity of the thermal property sensor, in such a way, that the portion of the fluid is essentially stationary in the measurement cavity; - measuring at least one thermal property (x, pCp) of the fluid; and - compensating the measured flow rate for the at least one measured thermal property.
