Kembs Project
Plant size - 150 MW

In 2006, in their search for a cost-effective alternative to current meters, DTG, an engineering unit of Electricité de France, decided to use the ASFM for turbine flow measurements at their Kembs plant.
Kembs is a typical low head plant equipped with Kaplan turbines and short intakes. ASL AQFlow were contracted to perform measurements at Unit 1 on an equipment rental basis, together with field training. The measurements were successful, and led to DTG purchasing the ASFM with the intent of performing future measurements in short intakes with in-house personnel.

Pinet Project
Plant size - 34 MW

In preparation for using the ASFM for contractual measurements, in 2007 EdF DTG performed an internal comparison on Units 4 and 5 at their Pinet plant, using three flow measurement techniques: acoustic time-of-travel, chemical tracer and acoustic scintillation. These measurements allowed DTG to assess the uncertainty levels associated with the ASFM measurements in plant configuration similar to Pinet. Further comparison measurements at plants with different intake configurations are planned.

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, Electricité de France and Douglas County PUD 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.
