Sentinel V (1000kHz; 500kHz; 300kHz)
The self-contained Sentinel V is the first in a series of exciting, next-gen Acoustic Doppler Current Profilers (ADCPs) to be released by Teledyne RD Instruments. Building upon the unparalleled success of our Workhorse ADCP products, our next generation V products offer a new level of features and versatility.
With profiling ranges from <1m to >150m and a 200m depth rating, the Sentinel V ADCP is ideally suited for a wide variety of coastal applications.
The lightweight and adaptable Sentinel V is easily deployed on buoys or mounted on the seafloor. Real-time data can be transmitted to shore via a cable link or acoustic modem, or data can be stored internally for short
or long-term deployments. With a pressure sensor delivered standard in Sentinel V, this highly versatile tool can be easily upgraded via an electronic firmware update to calculate directional and non-directional wave parameters.
