Abstract
An improved centrifugal pump having an integral pump/orifice plate located at either the pump discharge nozzle or suction nozzle for improved fluid flow measurements through the pump casing, and a process for measuring fluid flow through such a centrifugal pump casing is disclosed wherein the static pressure of a fluid being pumped by the pump is measured at a first point in the inlet or outlet area of the pump and at a second point removed along the nozzle, the pressures are compared to a pre-determined flow constant of the casing.
