摘要： A system of the present invention monitors the quality of steam flowing in a pipeline includes a test cell which is connected inline into the pipeline and has the steam flowing through it. A plurality of electrodes are located within the test cell and cooperate with the test cell to provide capacitance signals corresponding to capacitances of the steam passing between the electrodes and the test cell. The electrodes have different spacings between them and an interior wall of the test cell. A sensor senses the temperature of the steam flowing through the test cell and provides a temperature signal corresponding to the sensed temperature. Another sensor senses the pressure of the steam and provides a pressure signal corresponding to the sensed pressure. Circuitry connected to the test cell, to all the electrodes, to the temperature sensor and to the pressure sensor measures the quality of the steam in accordance with the temperature signal, the pressure signal and one of the capacitance signals.
