SonTek Argonaut-XR Profiler

PriceRequest Pricing


The Argonaut-XR offers exceptional value for near-shore deployments in less than 40 m of water. Designed specifically for mounting on the bottom of a river, channel, or harbor, the XR features a special mode that automatically adjusts one of its measurement cells for changing water levels. Its small size, rugged build, and flexible system architecture make the XR attractive for real-time operation and autonomous deployments.

  • Software

    View Argonaut Software - V 3.72

    ViewArgonaut is a Windows-based deployment, postprocessing, and diagnostic software program that can be used with any SonTek Argonaut current meter (MD, SW, XR, Argonaut-ADV and SonTek-SL500).

    Argonaut-SL/SW/XR Firmware - V 12.2

    Recent update corrects Modbus Output "Level" Parameter: The Modbus output of the "Level"parameter in Register 30051 & 30052 was corrected to not include the SystemElevation used in the "Stage" parameter and the flow calculations. It is now simply the water level above thevertical beam as intended. The changedoes not affect any other output formats (i.e. SDI-12) or internally recorded data.

    Previous udpates include:

    • Adds two new Channel Types (Culvert and Equation)
    • Improved Total Volume calculations; allows accumulating volume even when collection is temporarily interrupted
    • Option added to disable Total Volume Reset on the Flow Display
    • Adds SDI-12 Auto Sampling, which allows instrument to continue data collection even when no data logger command is received
    • Improved low-battery recovery; allows automatic data collection restart if a low-voltage battery recovers (e.g., when battery recharges itself via a solar panel)
    • Adds an alternate method of interrupting data collection via a modem using plus (+) or equals (=) characters
    • Scaling of analog output signals now based on setting of Total Volume units

    If you wish to take advantage of the new features in this version, follow the instructions below based on the version of firmware currently in your system.

    Argonaut SL/SW/XR Firmware Version 7.0 or Later

    This is a free update for systems that currently have v7.0 or later firmware installed. We strongly recommend updating your system to this new version. To update your system to this version:
