Abstract:
A device for measuring the flow rate of a substantially continuous fluid flow comprisinga conduit for transporting in a selected direction a continuous fluid flow varying in height up to a maximum height wherein said maximum height is less than the height which would occlude said conduit; a detector positioned relative to said conduit for determining the height of a selected section of said substantially continuous fluid flow at a first predetermined location and for determining at a second predetermined location located in a selected direction and a known distance from said first predetermined location that said selected section of said continuous fluid flow has traversed from said first predetermined location to said second predetermined location; and a processing device operatively connected to said detector for deriving the cross-sectional area of said selected section of the substantially continuous fluid flow from said height of a selected section determined by said detector at said first predetermined location, determining an elapsed time for the selected section of said continuous fluid flow to transverse said known distance and for calculating therefrom the fluid flow of said substantially continuous fluid flow through said conduit.
