Prototype tests of an acoustic flowmeter system were made in a 24-ft-diam power penstock at Oahe Dam to evaluate the system prior to permanent installation in the outlet works at Summersville Dam. Comparative discharge measurements included acoustic, penstock pressure-momentum Gibson, turbine model test ratings, scroll-case pressure differential Winter-Kennedy flowmeter, and surge tank volume changes. The acoustic flowmeter measurements were very consistent and many of the comparisons were within 1. The location of the measuring section for a single-path acoustic flowmeter must be selected to give a known or measurable relation between the flow pattern of the whole section and that along the acoustic path.
