ABSTRACT:
An apparatus, systems, and methods for measuring an amount of oil in a flow of fluid are provided. A housing defines an interior passage configured to pass a flow of fluid. A capacitance sensor, which suitably is a pair of insulated electrodes, is configured to respond to a capacitance of the flow of fluid is disposed within the interior passage of the housing. The capacitance sensor is coupled to conductors through which a first analog signal is generated. These conductors can be engaged to measure the capacitance of the flow of fluid. A conductance sensor configured to measure conductance of the flow of fluid also is disposed on the interior passage of the housing and generates a conductance signal as a second analog signal. The first and second analog signals can be used to assess the relative percentages of oil and water in the flow of fluid.
