Abstract
A sensor for measuring water fraction in a fluid mixture flowing in a conductive tubing within a borehole. The sensor comprises: an active probe, a reference probe, and an electronic unit. The active probe includes a first electrode and a second electrode isolated from each other by a first insulating layer, the first and second electrodes are preferably in contact with the fluid mixture. The reference probe is formed from an internal wall of the conductive tubing contacting the fluid mixture and isolated from the reference probe by a second insulating layer. The electronic unit is coupled to the first and second electrodes, and to the reference probe, the electronic unit preferably includes a capacitance module for measuring a capacitance between the active probe and the reference probe.
