Abstract

A fluid characterization sensor comprising a plurality of sensor segments is disclosed. Each segment comprises two electrodes, spaced apart so the fluid in the corresponding interval of depth for that segment is positioned between them. Complex current or impedance is measured by exciting one electrode with an AC signal, and measuring the amplitude and phase of the current in the other electrode. After automatically measuring and accounting for pre-determined gain, offset, temperature, and other parasitic influences on the raw sensor signal, the complex electrical impedance of the fluid between the electrodes is calculated from the measured phase/amplitude and/or real/imaginary components of the received electrical current signal and/or the variation of the measured response with variation in excitation frequency. Comparison of measured results with results taken using known fluids identifies fluid properties. Alternatively, measured results are compared to predicted results using forward models describing expected results for different fluids or contaminants.
