A method for measuring flow rate of a continuous fluid flow is shown. The method comprises the steps of generating a first signal at a first predetermined location representing a height of a selected section of the continuous fluid flow at the first predetermined location and for generating a second signal at a second predetermined location located in a selected direction and a known distance representing that the selected section of the continuous fluid flow has traversed from the first predetermined location to the second predetermined location; generating a third signal representing the conductivity of the fluid; receiving the first signal, the second signal and the third signal and creating a data stream therefrom; calculating from the data stream an elapsed time for the selected section of the continuous fluid flow to traverse the known distance; calculating from the data stream an average conductivity of the fluid from the data stream; deriving the cross-sectional area of the selected section from the height of the selected section compensated for variance in conductivity; calculating the volume of fluid flow using the cross-sectional area and elapsed time; and generating an output signal representing the calculated volume of fluid flow.
