  • Fluid flow measurement correcting system and methods of constructing and utilizing same
    Patent number: 6208943
    Abstract: An apparatus for calculating fluid flow in a channel including a very low profile probe which detects fluid depth in the channel; a mechanism for measuring average fluid velocity in the channel; a mechanism for correcting the detected fluid depth based upon the measured average fluid velocity to account for drawdown; and a mechanism for calculating average flow rate based upon the average fluid velocity measurement and the corrected fluid depth value. The probe has a height to width ratio of less than 0.52.
