Abstract:
An apparatus for measuring an amount of oil in a flow of fluid having a depth, the apparatus comprising:a support structure configured to be submerged in a flow of fluid and to support a plurality of sensors; and a plurality of sensor arrays disposed on the support structure, each of the sensor arrays being disposed at positions corresponding to varying depths of the flow of fluid and being configured to measure properties of a localized flow of fluid, each of the sensor arrays including: a capacitance sensor being configured to respond to a localized capacitance of the localized flow of fluid adjacent to the capacitance sensor, the capacitance sensor being coupled to a pair of conductors; and a conductance sensor configured to measure a localized conductance of the localized flow of fluid, the conductance sensor being configured to generate a conductance signal.
