An apparatus and method for continuous measurement of water volume in oil in which a dielectric capacity probe is placed inside the main pipeline, to measure the average dielectric constant (E) of the flowing mixture. This 'in situ' sampling, will account for the entire cross-sectional area of the pipe or duct and its contents. The 'in situ' probe will have a high intrinsic capacitance approaching that of air, which has a dielectric constant equal to "1". The probe placed within the pipeline shall offer a minimal impedance to flow of the crude oil and the oil's normal impurities and sediments. The probe will automatically self-calibrate, 'in-line', at selected time intervals and shall be fully automated for the overall routine operation. Additionally the present invention to continuously corrects the measured capacitance as the temperature fluctuates throughout delivery.
