Product Description
The Geolux RSS-2-300W radar sensor uses radar technology for providing contactless measurement of surface flow velocity. Contactless radar technology enables quick and simple sensor installation above the water surface with minimum maintenance. The radar operates in K-band (24.075 GHz to 24.175 GHz) and provides flow speed readings 10 times per second over serial RS-232, RS-485 Modbus, and analog 4-20 mA output. The instrument is easily integrated with Geolux or third-party dataloggers and all of the settings can be remotely configured. An integrated MEMS sensor is used for automatic angle compensation. Internal vibration monitoring and SNR calculation can be used for measurement quality assessment.

Geolux holds two calibration certificates from the Federal Institute of Metrology (METAS), the Swiss national metrology institute. The Federal Institute of Metrology (METAS) serves as the federal center of competence for all measurement issues, equipment, and procedures. METAS stands at the cutting edge of measurement accuracy in Switzerland. It develops the national measurement base. That is to say, it looks after the physical implementation, mutual comparison, and thus the international recognition of measurement units. For this purpose, it operates the necessary laboratories and conducts the research and development needed.
