Product Description
The Geolux RSS-2-300 W flow meter uses radar technology to provide 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 the K-band (at 24.125 GHz), and provides 20 flow speed readings per second over serial (RS-232, RS-485) and CAN interfaces. A variety of supported communication interfaces and protocols enable easy integration with existing telemetry equipment and SCADA systems. The 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.
Applications

Open Channel Flow Measurement

An RSS-2-300 W surface velocity radar provides precise, contactless measurement of surface flow velocity in open channels. Unlike ultrasound-based flow velocity sensors, the radar sensor is immune to air temperature and air density changes. The radar is enclosed inside a robust, IP68-rated, waterproof enclosure, making it immune to harsh environmental conditions. The sensor is mounted above the water surface.

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 and tubes within an industrial facility. Geolux RSS-2-300 W radar is also perfectly suited for use in various water and sewage processing facilities, hydro power plants, etc.
