ADV Family of Products

Since the original invention of the 10-MHz ADV (Acoustic Doppler Velocimeter) by SonTek, the ADV has developed into a family of products appealing to a broad range of applications. With ADV models available in three acoustic frequencies, and with its multi-sensor and integration capabilities, ADVs are more diverse and capable today than ever before. Just during the past couple of years, there have been several major additions and improvements to the ADV product line, including:

Increased sensitivity

Improved amplitude measurement accuracy

Integration with a wide variety of sensors

A smaller Delrin housing that reduces flow disturbances

An increased variety of probes for special applications

Underwater connector on probe housing is now standard

RS-485 capability

Typical ADV Applications

Low Flows
Turbulence
Small-scale structures
Boundary layer
Acoustic altimetry
Coastal oceanography
Open-channel flow
Flow-field mapping
Sediment transport
Water treatment
High-precision, single-point measurements

Whether your application is in the laboratory, the ocean, or a river or stream, there is an ADV configuration to suit your needs.

Acoustic Doppler Velocimeter Family of Products

10-MHz ADVField

The 10-MHz ADV Field Probe has been made stronger and more durable for outdoor use in rivers, streams, and water treatment applications.
A new underwater connector greatly facilitates probe change-outs in Field or Lab units.
Our SonLink protocol allows multiple ADV Field systems to be controlled and synchronized via RS-485.

ADV Probes

(Left) - The 5-cm laboratory probes can be used with 16-MHz MicroADVs and 10-MHz ADVs.
(Middle) - The ruggedized 10-cm field probe for 10-MHz ADVs.
(Right) - The sturdy 18-cm, 5-MHz ADV Ocean Probe is ready to withstand the abuse of pounding waves in the surf zone.

FlowTracker
Handheld ADV

Designed with the field user in mind, the FlowTracker easily attaches to top-setting wading rods for use in streams and a variety of shallow-water, open-channel environments.
Features an automatic discharge algorithm that is used by the U.S. Geological Survey.
Keypad interface with real-time velocity display.
No external batteries or computer required for data collection.
Laboratory-proven ADV Doppler technology - up to 15 times better than electromagnetic flowmeters. Capable of measuring velocities down to 0.001 m/s (0.003 ft/s) and in water as shallow as 2 cm (~1 inch).
2D/3D current measurement
