The global leader in high accuracy data collection…
The self-contained Sentinel is Teledyne RD Instruments’ most popular and versatile Acoustic Doppler Current Profiler (ADCP) configuration, boasting thousands of units in operation in over 50 countries around the world.
By providing profiling ranges from 1 to 165m, the high-frequency Sentinel ADCP is ideally suited for a wide variety of applications. The Sentinel also offers unbeatable precision, with unmatched low power consumption, allowing you to collect more data over an extended period.
The lightweight and adaptable Sentinel is easily deployed on buoys, boats, 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. The Sentinel is easily upgraded to include pressure, bottom tracking, and/or directional wave measurement—for the ultimate data collection solution.
Frequency: 300, 600 or 1200 kHz
Max range: 150 meters
Configuration: Self-contained or vessel mount

Highlighted Application:ADCPs aid in Treasure Hunt
…The ship sank at the entrance to a channel between two of the islands. Heavy tidal currents, funneled through the islands, are exacerbated by strong winds. Once the Sauternes was located, approximately 100m down, a self-contained RD Instruments 300kHz Workhorse Sentinel ADCP™ was bottom-mounted in the area to determine the patterns of current fluctuation.

Fugro GEOS Innovation in Gulf of Mexico
Fugro GEOS had a problem: their client BHP was about to drill the second-deepest well in the world, on the Walker Ridge Block in the Gulf of Mexico. The well was located at a depth of 2680m (8800 feet) in an area where water currents could threaten the marine riser. Traditional ADCP (acoustic Doppler current profiler) current measurement equipment could only reach up a little over 1000 meters in good conditions. What to do?
Get innovative, that’s what.

Highlighted Application: ADCP Data Helps Moves Big Rig
Imagine the costs and risks involved in moving an oil-drilling rig to a location affected by both tidal currents and the Gulf Stream. or a recent operation, Coastal Ocean Associates (COA) of Nova Scotia used a new approach. They installed a downward-looking 300 kHz Workhorse Sentinel ADCP™ on a buoy moored adjacent to the destination production platform.

Highlighted Application: ADCP for Sediment Concentration
Acoustic Doppler current profilers (ADCP) are becoming the standard for measuring current speed both at stationary locations and as ship-borne, moving sensors. Over the past decade there has been increased activity in developing methods to measure SSC using acoustic backscatter intensity from such acoustic current profiling systems.
