MULTI-PHASE COMPENSATED SPINNER FLOW METER

摘要

A compensated flow measuring system for measuring a multi-phase fluid flow in a well. An impeller (35) intercepts a downhole multi-phase flow. Capacitance and conductivity sensors are mounted in probe (50) and in close proximity to the impeller and provide measure of electrical admittance of the fluid. The electronics system (15) contains a phase detector for separating the capacitive and conductive signals and providing a signal related to a compensated multi-phase flow rate.
