1. A system for use in a well, comprising:
a completion system deployed in a wellbore and including a first internal flow path through which a well fluid is produced;
a sensor system comprising:
a pipe including a second internal flow path through which at least a portion of the well fluid flows;
a sensor including a main electrode, a guard electrode, and an insulator encapsulating the main electrode and the guard electrode, wherein the main electrode, the guard electrode, and the insulator are disposed in a wall of the pipe and are circumferentially arranged around the second internal flow path of the pipe, and wherein an inner surface of the insulator is flush with the second internal flow path; and
a processing system coupled to the sensor system and configured to determine a fraction of water in the well fluid from capacitance data obtained from the sensor.
