Geolux RSS-2-300 WL flow velocity and level meter uses radar technology to provide precise contactless measurement of surface flow velocity, and ultrasonic robust sensor for measuring the distance from the sensor to the water level. Contactless radar & ultrasonic technology enables quick and simple sensor installation above the water surface, and requires minimum maintenance.
RSS-2-300 WL flow meter is used to monitor flow velocity and level 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. Ultrasonic level sensor operates in frequency range between 20 kHz and 350 kHz.
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 WL radar sensor is certified according to both European and American standards, and is being used worldwide.
Radar Configurator Software
Geolux provides a user-friendly RSS-2-300 Water Flow Radar Configurator PC software free of charge. The software connects to the RSS-2-300 WL flow meter over serial port and can be used to configure flow meter operating parameters. Additionally, the Configurator utility also displays the measured flow speed over time.
The Configurator utility allows users to change the output data protocol, to select serial baud rate, change and configure various measurement and averaging algorithms, and to control the radar orientation.
RSS-2-300 Water Flow Radar Configurator runs on Windows XP or later, both 32-bit and 64-bit.
