Design of Water Holdup Measurement System for Oil-water Two-phase Flow Based on Conductivity Method
A simplified and reliable oil-water two-phase flow water holdup measurement system was designed to address the issues of complex measurement circuits in traditional conductivity methods.The system employed a voltage divider circuit to detect voltage signals from the conductance sensor,and converted the signal into a DC signal related to the water holdup via a precision full-wave rectifier circuit,which simplified the measurement circuit.Moreover,the integration of a multiplexing module and sensor array enabled multi-point detection of water holdup,expanding the detection range.The experimental results show that the output voltage of the system shows a good correlation with the water holdup.When the water holdup is 50%～90%,the sensitivity can reach at least 0.021 V/%.When the water holdup is 90%～100%,the sensitivity reaches the maximum value of 0.131 V/%,highlighting its excellent suitability for water holdup detection in high-water-content environments.
