Velocity Radar

Non-contact open channel surface velocity measurement

OTT SVR 100 surface velocity radar sensor

OTT SVR 100 — Surface Velocity Radar

The OTT SVR 100 is the ideal sensor for collecting surface water velocity measurements without being installed in the water. Compact radar sensor with integrated SDI-12 interface. Provides data during floods or high suspended sediment events.

  • Non-contact measurement — mounted above the water surface
  • Ultra-compact mounting design with flexible angle of inclination (vertical or horizontal)
  • Integrated SDI-12 interface (also SDI-12 over RS-485)
  • Integrated vibration and tilt sensors — identifies data influenced by sensor movement
  • Compatible with OTT Prodis 2 software for system calibration
  • Safe from rising water levels and floating debris
  • Reduces field visits and total cost of ownership
