The paper presents a sensor for the capacitance tomograph used for tests of two-phase flows. Structure of the sensor was described, and the proposed solution was compared with typical sensors applied in capacitance tomography. Increase of sensitivity near the pipeline wall seems to be the most important advantage of the proposed solution. It is desirable because of phenomena occurring in during tests of two-phase gas-liquid flows, especially downward flows. The paper presents also the measuring system and the results obtained from the tests performed at the special measuring stand. The obtained test results were compared with the results for a typical capacitance sensor with the electrodes of the same dimensions.
