- Model OTT SVR 100 - Surface Velocity Radar for Measuring Open Channel Flow

From

1
OTT SVR 100 is a simple, non-contact, compact surface water velocity radar sensor. Designed for measuring flow in open channels and rivers where reliable velocity data is required continuously, during floods or periods of high concentrations of suspended sediments. The sensor is mounted above the water surface, away from floating debris using a flexible bracket for vertical or horizontal installation. Velocity measurements and sensor status information from the integrated vibration and tilt sensor is available via SDI-12 over RS-485 and Modbus.

  • Usage Type: Fixed installation 
  • Product Highlights: Identify data influenced by sensor movement (e.g., wind, traffic) using meta data from integrated vibration and tilt sensors.
  • Application fields: Non-contact surface velocity radar 
  • Internal data logger: No 
  • Measurement range: 0.08 ... 15 m/s (0.26 … 49 ft./s

Open channels, including:

  • River
  • Streams
  • Canals
  • Irrigation canals
  • Process water canals
  • Outlets / inlets

Velocity Measurements:

  • Continuous non-contact surface velocity measurements during low, normal or high flowIdentify data influenced by sensor movement (e.g., wind, traffic) using meta data from integrated vibration and tilt sensors
  • Automatically detect flow direction
  • Eliminate/reduce effects of wind, precipitation, vibration, or waves by setting site specific filter

Installation / Maintenance:

  • Sensor unaffected by floating debris or suspended sediment by installing above the water surface
  • Flexible sensor mounting for quick installation on horizontal or vertical structures
  • Easily conceal sensor with compact size and flexible mounting options
  • Virtually maintenance free

System Integration / Compatibility:

  • Simple system integration, no deep knowledge required
  • Low power, ideal for powering with solar power
  • Easily integrate with new or existing systems using SDI-12 (over RS-485) or Modbus protocols
  • Compatible with OTT Prodis 2 for system calibration
