Features:

    The RAVEN-EYE® is a new generation radar velocity sensor. In combination with an appropriate level sensor, it provides an improved approach to open channel flow monitoring compared to older radar flowmeters. The new sensor combines advanced digital Doppler radar velocity sensing technology with most modern and powerful DSP processor technology allowing a patent pending selflearning average velocity calculation.

    The need for empirical models or time consuming site calibration become obsolete. A combined or detached ultrasonic or radar level sensing device or a submerged bubbler or pressure sensor convert’s the RAVEN–EYE® into customtailored non-contact open channel area/velocity flow meter.

    Use the RAVEN-EYE® in combination with the RTQ flow logger series for portable monitoring and for permanent monitoring with the UNI-TRANSTM which displays flow rate, velocity level and much more. The RAVEN-EYE® provides the user with highly accurate flow measurements under a wide range of flow and site conditions. By measuring the velocity of the fluid above the water surface, the RAVEN-EYE® eliminates accuracy and reliability problems inherent with submerged sensors, including sensor disturbances and sensor fouling.

    The RAVEN–EYE® is ideal for monitoring flows from corrosive liquids or with high solids content. The RAVEN-EYE® has an open communication standard allowing the sensor to be connected to PLC’s or third party loggers and monitors.
