The design of the sensor electronics for a tomographic imaging system based on electrical capacitance sensors is described. The performance of the sensor electronics is crucial to the performance of the imaging system. The problems associated with such a measurement process are discussed and solutions to these are described. Test results show that the present design has a resolution of 0.3 femtofarad (For a 12-electrode system imaging an oil/gas flow, this represents a 2% gas void fraction change at the centre of the pipe) with a low noise level of 0.08 fF (rms value),

Furthermore, the paper contains info such as current detectors, measurement, data acquisition, the capacitance measuring, capacitance measuring circuit, detectors, the sensor electronics, the imaging system, tomographic imaging, and circuit.
