High-precision Surface Velocity Radar Sensor For Flow Velocity Monitoring.

Geolux RSS-2-300 W surface velocity radar sensor is a revolutionary flow speed sensor.Geolux RSS-2-300 W provides precise contactless measurement of surface flow velocity. Contactless radar technology enables quick and simple sensor installation above the water surface, and requires minimum maintenance.

RSS-2-300 W flow meter is used to monitor flow velocity of open channels such as rivers, irrigation channels or sewer systems, and for monitoring and control of hydropower plants and wastewater treatment plants. The flow meter is also suitable for various mass flow metering applications in mining processing plants, industrial installations, and, due to operation without moving parts and robust mechanical design, is ideal for measurement of flammable fluids and harsh chemical applications.

The radar operates in K-band (at 24.125 or 24.200 GHz), and provides flow speed readings 20 times per second over serial (RS-232, RS-485) and CAN interfaces. Variety of supported communication interfaces and protocols enable easy integration with existing telemetry equipment and SCADA systems. Integrated tilt sensor measures inclination angle of the sensor and the flow velocity measurement is automatically cosine-corrected according to the measured mounting tilt angle.

Geolux RSS-2-300 W radar sensor is certified according to both European and American standards, and is being used worldwide.

HydroSpan Ltd is the exclusive distributor and service partner of Geolux RSS-2-300W in Asia & Russian Federation.HydroSpan is also authorised by Geolux.d.o.o to sell RSS-2-300W globally.

Open Channel Flow Measuremen

RSS-2-300 W radar provides precise contactless measurement of surface flow velocity. Unlike ultrasound-based flow velocity sensors, the radar sensor is immune to air temperature / air density changes. Since the radar is packed inside IP66-rated waterproof enclosure, it is perfectly suitable for measuring open channel flow. The radar can be mounted either above the stream or sideways. The radar supports multiple communication interfaces and protocols, which makes it easy to integrate in an existing SCADA system.

Industrial Flow Measurement

RSS-2-300 W radar can be used for precise flow measurement in all kinds of outdoor and indoor industrial facilities. Since the radar waves propagate through plastic materials, the radar can be used to measure flow speed inside plastic pipes/tubes within an industrial facility. Geolux RSS-2-300 W radar is also perfectly suited for use in various water/sewage processing facilities, hydro power plants etc.
