"Using dimensional anlaysis [sice] it was shown that the rotor response of a meter with vertical axis can be expressed independently in terms of a ratio of the drag coefficients of the driving elements and the submerged weight of the rotor. Experimental results from tests on a conventional Price meter rotor and a modified plastic price meter rotor were used to examine the effects of changing drag coefficients and submerged weight on general rotor performance and threshold velocity.The results indicate that considerable improvement in measuring low velocities may be obtained by using a rotor having the geometry of the conventional Price meter, and a substantially reduced submerged weight. Further tests are presently under way"--Summary, p. i. Includes abstracts in French. gccst Hydrology gccst Tooling DeZeeuw, C. Canada. Environment Canada.
