Effects of Turbulence on Price AA Meter Rotorsby Janice M. Fulford, Stennis Space Center, United States,
Abstract: Field and laboratory studies were conducted during 1988 and 1989 by the U.S. Geological survey to determine the effect of turbulence on the performance of price AA meter rotors. Two different rotors, the standard, hollow-cup metal rotor and an experimental, solid-cup polymer rotor, were used in the experiments. The field study compared the performance of the two rotors in natural streams in the continental United States. The two rotors had a significant registration difference in the field experiment. The laboratory experiments found that both rotors have registration errors for oblique flows. The hollow-cup metal rotor on average performed better than the solid-cup polymer rotor in laboratory experiments.
