ABSTRACT:
An improved pump casing and process for measuring fluid flow through a centrifugal pump casing is disclosed wherein the static pressure of a fluid being pumped by said pump is measured at a first point in the pump discharge inlet area of the pump adjacent the flow arm 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.
