Abstract
A venturi structure is supported below an ESP preferably off its gauge assembly below its motor so that the surrounding casing or wellbore defines the venturi path leading to the suction connection of the ESP. Multiple pressure sensing locations are provided in case the gauge that defines the venturi path is disposed off center in the bore or if the bore is on an incline. The gauge can receive forms of different sizes depending on the size of the surrounding tubular where the forms use an incline of preferably 15-20 degrees and allow for measuring differential near the perforations and at the constriction location so that the flow can be computed using the Bernoulli Equation.
