Measuring intake flows in hydroelectric plants with an acoustic scintillation flowmeter
- ASL Environmental Sciences, Inc., British Colombia (Canada)
The Acoustic Scintillation Flowmeter (ASFM) offers some unique advantages for measuring intake flows in hydroelectric plants. The method is non-intrusive, resulting in a minimum of flow interference and is well-suited to use in low-head dams and other applications where intake tunnels are short or have awkward geometries. Deployment in intake gate slots is straightforward, allowing data to be collected quickly and easily, with a minimum of plant down-time. An example of such flow measurements is shown. Interest in assessing the capability of the ASFM to make the highly-accurate measurements suitable for system efficiency evaluations led to our performing a series of tow-tank tests. Over a range of speeds from 0.5 to 5.0 m/sec, the mean deviation between the towing speed and the ASFM measurements was less than 0.5%. Measurements at an instrumented dam site are planned as the next stage in the accuracy assessment.
