摘要：

Regarding the importance of wet saturated steam dryness measurement, at the same temperature and pressure the dielectric constant of water is much greater than that of steam. When the wet steam flows by the capacitive sensor, the sensor capacitance changes with the steam wetness. A new method that barrel capacitor is presented to provide real-time and in-line measurement of steam quality. According to the calculation results and the theory data calibration, thus the present method solves the problems associated with industrial steam boilers and steam injection wells dryness in-line measurement.
