Smart floating element flowmeter based on a capacitive angular displacement transducer

Based on the detection mechanism of a capacitive angular displacement transducer, a new type of smart floating element flowmeter with a higher accuracy is provided in this paper. It mainly describes the principle of the flowmeter, design of the transducer, the intelligent signal processor, the calibration of the prototype and analysis of errors. Experiment results show that the accuracy of the kind of prototype investigated is better than 1%.
