Abstract
A fluid nozzle for a pipe having a flow meter includes an inner surface having a contour. The contour is substantially defined by a compound of two ellipsoidal bodies of revolution which prevents negative pressure gradients in the fluid along the inner surface as fluid in the pipe flows through the nozzle in the pipe. The nozzle includes a throat, wherein a ratio of a diameter of the throat to a diameter of the pipe upstream of the throat is 0.7 or less.
