Abstract:
1. An electric submersible pump assembly for downhole use in a wellbore defined by a wall to pump fluids to a surface through a tubular string, comprising: a motor driven pump assembly supported by the tubular string, said pump assembly pumping a fluid stream through the tubular string; a gauge housing supported by said motor driven pump assembly and shaped to define a venturi flow path between said gauge housing and the surrounding wellbore wall or an outermost surface on said motor driven pump assembly that defines a venturi flow path between said outermost surface on said motor driven pump assembly and the surrounding wellbore wall, said venturi flow path, in either instance, comprising two sloping surfaces spaced by a non-sloping surface which allows spaced pressure measurements for computation of flow rate; a measuring device associated with said venturi flow path to measure the fluid stream; said fluid stream passing only externally of said gauge housing or said outermost surface on said motor driven pump assembly up to an entry location on a pump of said pump assembly.
