A multiphase meter for a hydrocarbon-containing flow is provided to estimate the relative amounts of water, oil, and gas in the flow without separating the gas and liquid phases of the flow. The meter comprises a chamber for receiving and directing a flow vertically upward. A first capacitor assembly measures the capacitance about a central flow region of the chamber. A second capacitor assembly measures the capacitance about a peripheral flow region. The meter estimates the water content as a function of the peripheral capacitance and the gas content as a function of the arithmetic difference between the peripheral and central capacitance.
