THE WORLD LEADER FOR WATER
VELOCITY MEASUREMENT
www.sontek.com

Featuring a user-programmable cell extending up to 120 m
horizontally, flow disturbances caused by the mounting
structure can be eliminated by beginning the measurement
cell past the turbulence zone. The optional profiling
feature enables concurrent measurement of up to 10
additional equally spaced cells for quality assurance.
The Argonaut-SL is a side-looking acoustic
Doppler current and flow meter that precisely
measures water level and 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. Profiling, analog
output and waves extend the capability
of the Argonaut-SL to a wide range of
applications.
The Argonaut-SL outputs real-time velocity, level,
flow, total volume and diagnostic data in a variety
of communication formats. An optional Flow Display
box provides an easy-to-use interface for monitoring
both the output data and the system status.
Features
■ Water Level Measurement
■ Real-time Velocity, Flow, Volume
■ Multi-Cell Profiling
■ Waves
■ Power Ping
(Hi-Precision sampling)
When you need real-time flow output, the ViewArgonaut
software for Windows offers the easy answer for both
setup and analysis. Just select from one of our preprogrammed
cross-sections or enter your custom
geometry using our FlowWizard for a true flow
solution.

An Argonaut-SL can also provide water velocity information
next to a wharf, critical for ship berthing
operations. Similarly, an SL mounted on an offshore
platform can measure the water velocities across a
shipping channel to supplement a traffic management
system. The added benefit of the optional wave feature
is real-time wave spectra information.
