Uncertainty in the calibration of the D-49 suspended sediment sampler / P. Engel. : En13-5/94-55E-PDF

"Tests were conducted in a towing tank on the D-49 sediment sampler with carefully selected nozzles. Statistical analysis of the test data were conducted. It has been shown that individual samplers can be calibrated with a high degree of repeatability but that the variability of calibrations from sampler to sampler was quite high at the lower velocities. It was further shown that the performance of the sampler was sensitive to changes in the velocity coefficient of the 3.2 mm nozzle. Similar variabilities in the velocity coefficient for the 4.8 mm and 6.4 mm nozzles did not affect the performance of the sampler. Tests on other types of samplers are proceeding"--Abstract.
