Integrating-Float Measurements at Low Velocities
Flow measurement by the integrating-float method was tested in a rectangular flume 1 ft. wide and 2 ft. deep. Stainless steel hollow spheres, 5/8-in. diam., were used as floats. Accuracy of the technique was evaluated by comparing discharges measured with floats to those measured with standard weirs. For flows in the velocity range tested (between 0.02 and 0.3 fps), the average error for 40 runs was less than 2.5%, and there was no tendency for increase in error as velocity decreased.
