A method and device for obtaining an accurate flow rate measurement through a fluid flow system. A nozzle and gauge tapping combination is connected to a fluid flow system. Fluid enters the nozzle as turbulent flow. As the fluid passes through the nozzle, the turbulent flow is converted to laminar flow due to the shape of the nozzle. Once in laminar flow, the pressure at that point in the nozzle is constant, and therefore the pressure, and thus flow rate, can be measured with greater accuracy.
