RSS-2-300W-Series

RSS-2-300W Surface Flow Velocity Meter

Name: RSS-2-300W Surface Flow Velocity Meter
SKU: RSS-2-300W-Series

The Geolux RSS-2-300W is a highly sensitive Doppler radar sensor designed for the contactless measurement of surface flow velocity. Operating in the K-band (24.075 GHz to 24.175 GHz), the instrument leverages the Doppler effect to accurately measure the velocity of river flow at the surface. Due to its contactless operation, the RSS-2-300W offers quick and easy installation above the water surface, minimizing the need for maintenance.

Features

Contactless surface velocity measurement. The instrument reports flow speed and flow direction, and can detect flow reversal.
Accuracy validated by top laboratories worldwide.
RS-232, RS-485 Modbus, and analog 4-20 mA interfaces included.
Remote configuration of all instrument parameters.
Robust, small-sized IP68 aluminum or stainless steel enclosure.

Description

The instrument provides highly accurate flow velocity readings 10 times per second, which are transmitted via RS-232, RS-485 Modbus, and analog 4-20 mA outputs, ensuring seamless integration with Geolux or third-party dataloggers. An integrated MEMS sensor offers automatic tilt angle compensation and built-in internal vibration monitoring and SNR calculation for assessing measurement quality. The instrument’s accuracy has been confirmed by multiple laboratories worldwide, including METAS (Switzerland), WATIC (China), KICT (Korea), Brodarski institut (Croatia), and Central Water and Power Research Station (India).

The instrument is designed for continuous non-contact surface flow monitoring in hydrological networks according to WMO-No. 168.
