| 10-MHz ADV Operation Principles (1793 words) |
 | ADV Doppler processing techniques provide several important advantages: 3D velocity measurements in a remote sampling volume; invariant factory calibration (no periodic re-calibration required); simple operation; direct calculation of turbulent parameters such as Reynolds stress; and excellent low-flow performance. |
| An important result of the ADV sampling scheme is that reducing the sampling rate decreases the noise in each sample (by increasing the number of pings averaged per sample). |
| Additionally, the ADV automatically measures and records the distance to the boundary at the start of each data collection cycle (the boundary measurement can be made when the sampling volume is between 2 and 25 cm from the boundary). |
