Claim Text:
1. A fluid sensor for determining at least one parameter of a fluid of a wellbore, the fluid sensor comprising: a base positionable in the wellbore, the base comprising insulation; and a pair of electrodes operatively positioned in the insulation, the pair of electrodes having a first of the pair of electrodes interlaced with a second of the pair of electrodes such that at least a portion of the second of the pair of electrodes is surrounded by the first of the pair of electrodes, and wherein a space therebetween the first pair of electrodes and the second pair of electrodes is suitable for passage of the wellbore fluid therethrough, and wherein a capacitance between the portion of the second pair of electrodes surrounded by the first pair of electrodes is based on a cross-sectional shape of the second pair of electrodes and wherein the capacitance has a ratio of approximately 1:4 or 1:π; wherein a voltage applied across the pair of electrodes generates a current therebetween whereby at least one parameter of the wellbore fluid passing therethrough may be determined.
