Open Channel Flow Meters

Flow-Tronic RAVEN-EYE 2+ Open Channel Flow Meter (Non-Contact)

The RAVEN-EYE is the newest non-contact RADAR area/velocity flow meter sensor for open channel flow measurements. The new sensor combines advanced digital Doppler radar velocity sensing technology with modern & powerful DSP process technology allowing self-learning average velocity calculations. The need for empirical models or time-consuming site calibrations becomes obsolete.
