Abstract
A compensated flow measuring system for measuring a multi-phase fluid flow in a well. An impeller intercepts a downhole multi-phase flow. Capacitance and conductivity sensors are mounted in close proximity to the impeller and provide a measure of electrical admittance of the fluid. In one embodiment, the capacitance and conductivity sensors are mounted in at least one single probe mounted near the impeller. An electronics system contains a phase detector for separating the capacitive and conductive signals and providing a signal related to a compensated multiphase flow rate.
