SonTek Acoustic Doppler Water Velocity Measurement

Whether you are looking to collect flow data in rivers, streams or canals, or you need current profiles in deeper ocean environments, SonTek has an array of instrumentation that can be used in any body of water, at various depths.

Geotech is a SonTek representative in Colorado, New Mexico, Utah, and Wyoming.

FlowTracker®2

Water Velocity Meter

SonTek FlowTracker2
FlowTracker2 with Probe Attached

The new FlowTracker®2 (FT2) handheld Acoustic Doppler Velocimeter (ADV®) has all the technology you have grown to know and trust with the original FlowTracker, but now comes with functional, modernized features (Bluetooth, GPS and large color screen, to name only a few) based on the evaluation and feedback from hydrologists, researchers and scientists who have made the FlowTracker their instrument of choice.

SonTek-IQ™

SonTek-IQ

The SonTek-IQ™ starts with a custom flow algorithm derived from hundreds of field measurements. The four velocity beams profile water velocity both vertically and horizontally ensuring complete coverage of the velocity field. The built-in pressure sensor and vertical acoustic beam work in tandem to measure the water level. Simply input the channel geometry using the intuitive SonTek-IQ software and you are outputting flow data in minutes.

SonTek Hydroboard
SonTek Hydroboard used as a floatable platform for Riversurveyor systems

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. A deterministic microcontroller expertly apportions the proper acoustics, pulse scheme, and cell size to get the highest definition possible so you can focus on the measurement, not the instrument setup. The system even has a vertical beam for precise channel definition and it's all designed to work intuitively.

Argonaut-SL

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

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

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.
