This report details the proper installation and calibration techniques for hydroacoustic meters. The calibration procedure developed as part of this study is called the Flow Rate Indexing Procedure (QIP). The QIP can be competed by a professional technician with a boat-mounted Acoustic Doppler Profiler (ADP) or a standard current meter. Once the QIP has been used to properly calibrate a hydroacoustic flow meter, the device can then measure and record the flow rate and volume in a channel to within +/- 6% of actual values.
