Towing tank tests of the accusonic acoustic flow meter / by Peter Engel, Erwin Fast and John Todd.: En13-5/90-142E-PDF
"The Water Survey of Canada is in the process of acquiring a reliable, low cost, ultrasonic flow meter to measure river discharge at remote locations on a real time basis. Tests were conducted on the ACCUSONIC flow meter used by the United States Geological Survey (USGS). Analysis of the test data shows that measurements made with the USGS flow meter were lower than the reference velocity and this velocity deficit was found to increase gradually with increase in towing speed in the range from 0.6 m/s to 3.0 m/s. The reason for this cannot be determined conclusively from the present test, but is thought to be attributable to the space limitations in the towing tank and the flow meter. The low variability in velocity measurements was considered to be excellent considering the uncertainties as a result of the towing tank environment. A dimensionless flow meter coefficient was developed using dimensional analysis"--Summary, page iii.
