RSS-2-300 WL flow meter is used to monitor flow velocity and water level in open channels such as rivers, irrigation channels or sewer systems, and for monitoring and controlling 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 surface velocity 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. The level radar sensor operates in the W-band, between 77 GHz and 81 GHz.
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 WL instrument is certified according to both European and American standards, and is being used worldwide.
