Applications and Products

RiverSurveyor application softwareArgonaut-SW being used in irrigation applicationFrom the world's mightiest rivers, to the small stream in your backyard, SonTek/YSI has your water measurement solution. Years of on-the-job, water-resources field experience are at the core of how hydrological instruments are developed at SonTek. These influences have led to several of the most significant acoustic Doppler flow meter developments for the water-resources industry.

FlowTracker stream applicationArmed with SonTek tools that just a few years ago were unthinkable, hydrologists and technicians can now measure water velocity and flow with precision and efficiency that far surpasses conventional techniques. Included with each system is an industry-leading software package tailored to your application. Whether your water is hundreds of feet deep or just one-inch deep, whether it is moving fast or slow, or whether data needs to be stored internally or output in real-time, SonTek/YSI has a solution.

Water Resources Applications and Products
Products Typical Applications
Argonaut-SW
Shallow Water

SonTek/YSI Argonaut-SW (Shallow Water) current meterIdeal for monitoring flows in small channels from 0.5 to 16 ft (0.3-5 m) deep, the Argonaut-SW offers advanced Doppler performance for sites previously thought impossible to measure. Typically mounted on the bottom of a channel, stream, or pipe, the SW measures water level and vertically-integrated velocity, making it ideal for sites with reversing or stratified flow conditions. Argonaut-SW Details

  • Argonaut-SW Applications
    • Shallow water monitoring
    • Irrigation channels
    • Pipes, culverts
    • Natural streams
    • Storm water
    • Flood alert
FlowTracker Handheld ADV

FlowTracker Handheld ADVLaboratory-proven ADV technology in a compact, hand-held package. Precision, single-point water velocity measurements. The FlowTracker easily attaches to wading rods and offers unparalleled shallow water and low flow performance. Features a discharge mode based on USGS/ISO standards as well as a general purpose mode for water treatment or other applications. FlowTracker details

RiverSurveyor ADP

RiverSurveyor ADPs

Measuring flows has never been easier than with the RiverSurveyor Acoustic Doppler Current Profiling system. Designed specifically for use in rivers and open channels, the RiverSurveyor hardware/software accurately measures discharge from moving boats with unsurpassed accuracy and ease-of-use. Available in several configurations and acoustic frequencies, rivers can be profiled from less than 1 foot (0.3 m) to well over 300 feet (100 m). RiverSurveyor details

RiverCat System

RiverCat SystemThe RiverCat picks up where the RiverSurveyor leaves off by adding an integrated floating catamaran, battery power, and a wireless radio link. Weighing less than 25 lbs (12 kg), the RiverCat can easily be deployed as a tethered system from bridges or towed behind a small boat or even a kayak. An optional DGPS system makes the RiverCat a truly unbeatable package. RiverCat details

Argonaut-SL
Side-Looking

Argonaut-SL FamilyEasily installed on a riverbank, bridge abutment, or other vertical structure, the Argonaut-SL provides precise, 2D water velocity measurements in a horizontal layer. Because it measures remotely, the SL can avoid flow disturbances caused by the mounting structure. The SL supports the SDI-12 protocol, so it is easily interfaced to existing instrument arrays, or it can simultaneously record to its internal memory. The SL also supports current profiling and direct flow output in open channels. Options include a vertical beam for stage measurement and water quality instrumentation. Argonaut SL details

    • Currents
    • Discharge
    • Environmental
    • Estuaries
    • Flow
    • Irrigation canals
    • Open channel flow
    • Pollution monitoring
    • River gauging
    • Ship berthing
    • TMDL evaluation
    • Velocity indexing
    • Watersheds
Argonaut-XR
Extended Range

Argonaut-XR Current MeterThe Argonaut-XR offers all the features of the Argonaut-SL (including current profiling) in a 3D version intended for mounting on the bottom of a river or channel. The integrated pressure sensor allows a bottom-mounted XR to automatically adjust the position of the sampling volume with changing tide level or river stage. Argonaut XR details

    • Velocity indexing
Argonaut-ADV

Argonaut-ADVThe Argonaut-ADV uses the same technology as the FlowTracker for continuous single-point water velocity measurement in a compact package. Ideal for short-term field deployments or permanent installations, the Argonaut-ADV supports the SDI-12 protocol. Options include a built-in rechargeable battery, pressure sensors, and water quality instruments. Unparalleled low-flow and shallow water performance makes the Argonaut-ADV ideal for lakes, marshes, and estuaries. Argonaut ADV details
