"Five Price winter meters were calibrated together with other, similar current meters in a towing tank, four at a time, repeated ten times, for a total of fifty calibrations. Analysis showed that, accuracy of the calibration of the rod suspended meters depends on the number of meters calibrated simultaneously. Comparison with the same meters calibrated one at a time showed that uncertainties are significantly greater for meters calibrated four at time for velocities less than 0.7 m/s with presently used calibration procedures. Results suggest that longer settling times are required before each run at velocities less than 0.7 m/s when four meters are calibrated at the same time. Tests to investigate settling time requirements have been recommended"--Abstract.
