US Patent 9360444 Fluid sensor and method of using same

A fluid sensor and method for determining at least one parameter of a fluid of a wellbore is provided. The fluid sensor has a base positionable on a downhole tool and a pair of electrodes. The base is provided with insulation. The pair of electrodes is operatively positioned in the insulation. The pair of electrodes has a space therebetween for passage of the wellbore fluid therethrough. A first of the pair of electrodes is 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. A voltage applied across the pair of electrodes generates a current therebetween whereby at least one parameter of the wellbore fluid may be determined. The fluid sensor is deployable into the wellbore via the downhole tool.
