| Abstract: | A method for flowrate measurement was analyzed. It utilized eddy current sensors to measure th displacement. A corresponding target structure was designed. Then, the measurement system with th function of temperature and pressure compensation was constructed. Finally, the measurement model of th ftowrate sensor was established according to the data of the calibration experiments. The experimental result show that the flowmeter has good linearity and hight sensitivity with a measurement accuracy better than 1%. |
