摘要： A technique facilitates evaluation of a fluid flowing through a tubing and includes at least one sensor deployed along an interior of the tubing. Each sensor comprises a plurality of electrodes and insulation material disposed between the electrodes to isolate the electrodes from each other and to facilitate resistivity measurements. The plurality of electrodes comprises electrodes for emitting an electric current and for monitoring voltage so as to enable resistivity measurements with respect to fluid flowing through the tubing. The resistivity measurements may be used to determine a constituent fraction, e.g. a water fraction, of the fluid flowing through the tubing.
