Abstract :
A capacitive electromagnetic flowmeter working in voltage sensing mode is developed. The methods to keep noise to a minimum are described. The signal converter is designed to measure the signal from the sensor and get the flow rate. The prototype flowmeter is calibrated with water in a flow loop. After the calibration, the system is tested with oil-water two-phase flow. An electrode type electromagnetic flowmeter is also tested with oil-water two-phase flow. Test results show the capacitive electromagnetic flowmeter has better performance than the electrode type flowmeter for oil-water two-phase volumetric flow rate measurement.
