The temperature difference DELTAt between the resistance Rm and Rt is set by the fixed resistance (r), but constant irrelevantly to the fluid temperature when the resistances Rm and Tr have the same temperature characteristics. The power consumption (P) of the heater resistance Rh is expressed as P=Vout<2>/ Rh=(A+BXU<1/2>).DELTAt, where U is the flow velocity and A and B are constants. The flow velocity U is calculated from the power consumption P. Consequently, the measurement accuracy is improved.
