Laforge-2 Project
Plant size - 304 MW
Publication: presented at IGHEM98 (PDF format - 172kb)

LaforgeIn June 1997, Hydro Quebec measured turbine discharge at their Laforge-2 low-head plant with both the traditional current meters and the ASFM. Measurements were taken simultaneously at various operating conditions and using:
a) five fixed frame positions (using data from all four rows), and b) frame profiling continuously (using data from the lowest row). In spite of very low turbulence, (trash racks had been removed), the ASFM results were consistent with the current meters and confirmed that the ASFM is capable of the accuracy required to measure turbine discharge in low-head plants.

Alvkarleby Hydro Power Station, Sweden

Mellanfallet Project
Plant size - 22 MW
Publication: August 1999 (PDF format - 1.1mb)

MellanfalletSwed Power AB was looking for an innovative field spillway discharge measurement method, and selected the ASFM for testing at its Mellanfallet Dam in August, 1999. Testing went well for small spillway gate openings, however, for all larger openings, including fully open, the vortexing and air entrainment interfered with the acoustic signal such that meaningful discharge computation was not possible. It is believed that in future testing it will be necessary to move the measurement plane into an area of lower velocities where flow boundary separation, vortexing and air entrainment may be reduced or even eliminated.

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.
