10-MHz ADV

The SonTek/YSI 10-MHz ADV (Acoustic Doppler Velocimeter) is a proven, accurate solution for high-precision, 3-axis (3D), velocity measurements in a wide variety of settings from the laboratory to the ocean. ADV performance has been shown to compare favorably with laser Doppler systems costing ten times as much. In addition, the ADV is extremely simple to set up and use. Most users are taking high quality data within minutes of receiving the system.

16-MHz MicroADV

The SonTek/YSI 16-MHz MicroADV (Acoustic Doppler Velocimeter) is the most significant breakthrough in 3-axis (3D) current meter technology since the original SonTek ADV. The original SonTek ADV has compared favorably with Laser systems costing ten times as much — the MicroADV fares even better. The higher acoustical frequency of 16 MHz makes the MicroADV the optimal instrument for laboratory work. Like all SonTek instruments, the MicroADV is extremely simple to set up and use. Most users are taking high-quality data within minutes of receiving the system.

ADP

The SonTek/YSI ADP (Acoustic Doppler Profiler) is a high-performance, 3-axis (3D) water current profiler that is accurate, reliable, and easy to use. The ADP uses state-of-the-art transducers and electronics designed to reduce side-lobe interference problems that plague other current profilers. This allows the ADP to make the very near-boundary (surface or bottom) current measurements critical to shallow water applications. The 1.5 and 3.0-MHz profilers are available as Mini-ADPs featuring a compact transducer head designed for applications where small size is critical.

ADVOcean Hydra

The Hydra (package option featuring the ADVOcean probe) is a fully integrated, 3-axis (3D), ocean sensor system that includes a powerful data acquisition system, a high-resolution velocity sensor, a strain gage pressure sensor, and top-of-the-line sensors from other manufacturers all in one seamless package.

Argonaut-ADV

Providing robust velocity measurements in a compact, easy-to-use package, the SonTek Argonaut-ADV is the ultimate instrument for shallow water flow monitoring. Ideal for low-flow applications in shallow streams, marshes, lakes, or water treatment facilities, the 3-axis (3D) Argonaut-ADV's advanced Doppler technology measures single-point velocity away from flow obstructions.

Argonaut-MD

Combining unparalleled sensitivity and the reliability you expect, the Argonaut-MD (Mooring Deployment) acoustic Doppler current meter has become the instrument of choice in the oceanographic community. Capable of measuring water motion at a "single point" almost anywhere in the oceans, this 3-D, vector-averaging current meter is small, light, and inexpensive.

Argonaut-SL

SonTek's user interface allows easy operation with minimal training and experience. First time users can collect test data within minutes of receiving the Argonaut-SL. Deployments require only a few minutes to configure the Argonaut and start collecting data. The Argonaut-SL provides the highest quality Doppler velocity data without requiring the user to become an expert on Doppler technology.

Argonaut-SW

Monitoring flow in natural streams, concrete lined channels and pipes has never been easier than with the Argonaut-SW. This lightweight and compact system uses SonTek’s proven Doppler technology to measure flow, velocity and water level. The system is designed to account for velocity variations within the channel to produce the most accurate flow calculation possible.

Argonaut-XR

The Argonaut-XR offers exceptional value for near shore deployments in less than 40 m of water. Designed specifically for mounting on the bottom of a river, channel, or harbor, the XR features a special mode that automatically adjusts one of its measurement cells for changing water level.

Current Surveyor

The SonTek/YSI CurrentSurveyor is a state-of-the-art 3-axis (3D) acoustic Doppler current profiling system. CurrentSurveyor accurately measures velocity profiles from moving boats with unsurpassed accuracy and ease-of-use. The CurrentSurveyor combines advanced acoustic Doppler instrumentation with a software package that allows you to confidently measure current profiles in less time than ever.

FlowTracker Handheld-ADV

Designed with the field user in mind, the FlowTracker Handheld-ADV® (Acoustic Doppler Velocimeter) measures 2D or 3D currents, attaches easily to wading rods, and features an automatic discharge computation using a variety of international methods, including ISO and USGS standards. The FlowTracker also features SonTek’s exclusive "SmartQC" which involves a series of built-in data quality checks, so you know your data is right.

RiverSurveyor S5 and M9

The RiverSurveyor S5/M9 systems give a new perspective to the notion of measuring open channel hydraulics. Using SonTek’s exclusive SmartPulseHD™, multiple acoustic frequencies are fused with precise bandwidth control for the most robust and continuous shallow-to-deep discharge measurements ever.

Triton-ADV

The SonTek/YSI Triton-ADV is a single-point, Doppler current meter designed specifically for low-power measurements in shallow water. The Triton-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; and excellent low-flow, shallow-water performance.
