Abstract:
A method for measuring flow rate of a continuous fluid flow comprising the steps of:generating a first signal at a first predetermined location representing a height of a selected section of the continuous fluid flow having a known cross-sectional area at said first predetermined location and for generating a second signal at a second predetermined location located in a selected direction and a known distance from said first predetermined location representing that said selected section of the continuous fluid flow has traversed from said first predetermined location to said second predetermined location; creating a data stream from said first signal and said second signal; calculating from said data stream an elapsed time for the selected section of said continuous fluid flow to traverse said known distance; deriving the cross-sectional area of said selected section and compensating the derived cross-sectional area 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.
