ASL AQFlow Inc. produces acoustic scintillation flow measurement systems that are being globally recognized as the solution to hydro-electric’s toughest flow measurement challenge - turbine discharge measurements in low head, short intake power plants.

Naturally, AQFlow can also handle turbine discharge measurements under more favourable hydraulic conditions.

In combination with its parent company, ASL Environmental Sciences Inc., AQFlow over 25 years of experience with water velocity measurement, initially in ocean environments, and more recently in hydroelectric applications.

The collective knowledge gained from these years of experience has gone into the development of AQFlow's Acoustic Scintillation Flow Meter (ASFM).
