Douglas County PUD

Fort Patrick Henry Project
Plant size - 48 MW
Publication: HydroVision '98, Reno, Nevada (PDF format - 99kb)

On-site measurement supervision services, data analysis and a report for Wells Dam for turbine discharge measurements was carried out as a continuation of services by ASL AQFlow for Douglas County PUD #1 that has been carried out each year at different units since 2002. Back

Wheeler Project
Plant size - 404 MW

In 1999, TVA performed comparison discharge testing, using the traditional array of current meters and the ASFM, for two separate turbine settings. Upstream obstructions (horizontal beams supporting the trash-racks) resulted in a high level of turbulence, and the results from the two measurement methods differed by between 7% and 8%. It is unclear which technology was more accurate. Back

Note:

While the first measurement by a particular owner is typically carried out by AQFlow technical personnel, the user-friendly features of the ASFM offer the owners the choice of having the subsequent measurements carried out by AQFlow personnel (indicated above in italics) or by their own personnel (indicated by non-italics).

As shown, Nova Scotia Power, Hydro Québec, Korea Water Resources and Electricité de France have all opted for having their personnel trained by AQFlow technicians as part of the first project, purchasing the ASFM and performing all subsequent measurements in-house successfully and cost-effectively.
