Main Issue: Assessing Volume ofFlow Subject to Sampling• Ultrasonic Flow Meter is Unreliable in allInstances• Magnetic Flow Meter More Reliable butRequires Installation Effort• Ship Data on Discharge Rate and Tank LevelsReadily Available but Indirect and Unreliable• In Some Cases Treatment Systems Include aReliable Flow Meter in Installations• Not All Do
Conclusions: In-Line Sampling ofNatural Assemblages• Elbow pitot best in line approach;• In Line approach as good or better than best intank approach in terms of organism catch andlive densities
