Workhorse Sentinel ADCP 1200, 600 or 300 kHz
Profile Parameters
Velocity accuracy:
• 1200, 600: ± 0.25% of the water
velocity relative to the ADCP ± 2.5mm/s
• 300: ± 0.5% of the water velocity
relative to the ADCP ± 5 mm/s
Velocity resolution: 1mm/s
Velocity range: ± 5m/s (default):
± 20m/s (maximum)
Number of depth cells: 1-128
Ping rate: 2 Hz (typical)
Echo Intensity Profile
Vertical resolution: depth cell size
Dynamic range: 80 dB
Precision: ± 1.5dB (relative measure)
