Calibration of current meters for turbine efficiency tests / by Peter Engel.: En36-539/25-1985E-PDF
"At the request of Hydro-Quebec Engineers, calibrations were provided for 30 SIAP ME 4001 current meters. Investigations of sources of uncertainties in the calibrations revealed that there maybe a small systematic error due to the Epper Effect, a small random error due to towing speed variability and a significant error as a result of using proeller No. 1 which is not applicable for speeds greater than 500 cm/s. Theoretical analyses and tests indicated that satisfactory calibrations could be produced by towing three meters at a time and using 48 data pairs to determine the calibration equations. Tests conducted to determine the effect of replacing lubricating oil in the meter's bearing chambers with water showed that this procedure did not significantly change the calibrations for speeds greater than 50 cm/s"--Summary.
