Abstract: The classical technique of streamflow measurement by the integrating-float method is reexamined. The effect of float acceleration on discharges measured by the technique is analyzed using existing data for the acceleration of spheres in fluids in the gravitational field. Other sources of error, such as those due to the nonuniformity of flow, turbulence, secondary currents, fluid density stratification, etc. are described. It appears that this technique, after a sufficient development, may be particularly suitable for streamflow measurement at low velocities. Other potential advantages of it is also indicated.
