"Owing to the joint initiative of Water Survey of Canada and the Hydraulics Division of the National Water Research Institute, this study has been conducted to develop a plastic rotor for the Price meter with the best possible low speed performance. Preliminary designs have been obtained based on theoretical considerations and towing tank tests. Indications are that threshold velocities of less than 2 cm/s can be obtained. More extensive tests are planned to evaluate the consistency in the performance of the new rotor designs over a wider range of conditions"--Summary, p. i.
