Surface Velocity Radar – SVR Sensor

Accurate Non-Contact Surface Water Velocity Monitoring for Rivers, Canals & Flood Applications

The Surface Velocity Radar (SVR) Sensor is a high-performance non-contact monitoring solution designed to measure surface flow velocity in open channels, rivers, streams, and stormwater systems. Using advanced 24 GHz Doppler radar technology, the sensor detects the frequency shift of electromagnetic waves reflected from the moving water surface and converts it into precise surface velocity measurements. This allows reliable flow monitoring without direct contact with water, reducing maintenance and improving long-term performance. The SVR sensor is ideal for hydrological monitoring, flood warning systems, irrigation canals, wastewater channels, and environmental water management applications. Mounted safely above the water surface, it remains protected from floating debris, sediment, and harsh flow conditions while delivering continuous real-time monitoring even during floods and high suspended solids conditions.

Key Features:

  • 📡 Non-Contact Doppler Radar Measurement

    Uses advanced Doppler radar technology to accurately measure surface water velocity without direct sensor contact, reducing fouling and maintenance requirements.

  • 🌊 Wide Velocity Measurement Range

    Supports a measurement range from 0.05 to 15 m/s, making it suitable for both low-flow streams and high-velocity flood conditions.

Key Features:

  • 🎯 High Accuracy with Integrated Tilt Compensation

    Provides ±2% accuracy with integrated tilt and vibration sensing for stable performance and reliable data quality in challenging field conditions.

  • 🛡️ Rugged IP68 Outdoor Design

    Built with weatherproof housing and durable construction for long-term outdoor installation in harsh environmental conditions.

Applications:
