Measure the Flow. Capture the Data. Stay Connected.

The Stalker Surface Velocity Radars (SVR) are engineered for accurate waterflow measurement, making them ideal for applications in water resource management, environmental monitoring, and industrial operations. They measures water speed with high precision, ranging from 0.4 mph to 40 mph, ensuring reliable data collection in rivers, streams, and water treatment facilities.

Less time recording data. More time measuring what matters.

  • SVR2 Connect

    Fast, accurate, non-contact surface water velocity measurement, now with connected field data.

    From routine discharge surveys to high-flow and emergency flood response, SVR 2 Connect helps teams in the field measure, record, and manage critical velocity data where the work happens.

  • Your Field Data. Connected.

    Pair SVR 2 Connect with the Mobile App. Wireless connectivity brings live measurement data directly to the SVR 2 Connect mobile app on a compatible iOS or Android device.

    Once paired, the app can:
    • Display live readings
    • Add GPS location data
    • Log measurements by field session
    • Capture timestamped data
    • Help eliminate manual transcription
    • Make field data easier to export and share
