SonTek Acoustic Doppler Measurement

SonTek FlowTracker

Designed with the field user in mind, this handheld ADV®
(Acoustic Doppler Velocimeter) measures currents, attaches easily to wading rods, and features an automatic discharge computation using a variety of international methods, including ISO and USGS standards. At the end of the data run, just press a button and the FlowTracker calculates the discharge for you! With rugged construction for any climate and a backlit display easily read during both day and night, the FlowTracker goes wherever you need it to go.

Argonaut-SW

Monitoring flow in natural streams, concrete lined channels and pipes could never be easier than with the Argonaut-SW. This lightweight and compact system uses SonTek's proven Doppler technology to measure the 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-SL

The Argonaut-SL is a side-looking Doppler current meter that precisely measures 2-D water velocity in a horizontal layer. Because it is easily installed on a riverbank, bridge abutment, or other vertical structure, it is the perfect choice for long-term current monitoring. Options for water level measurement, water quality, telemetry, and flow calculation extend the capability of the Argonaut SL to a wide variety of applications.

Argonaut-ADV

Providing robust, laboratory-precision flow measurements in a compact and easy-to use package, the Argonaut-ADV is the ultimate solution to shallow water flow monitoring. Ideal for low-flow applications, it is equally versatile in higher velocity environments and when precise water velocity is needed close to a boundary.

Argonaut-XR

Designed specifically for mounting on the bottom and looking up, the low-profile Argonaut-XR is an advanced Doppler sonar for 3-D water velocity measurement. Because the Argonaut-XR vertically integrates water velocity from the bottom all the way to the surface, it is an ideal tool for sites where bi-directional flows are present. Optional CTDs and multiprobes can make it a complete environmental monitoring solution.
