Technical Specifications RAVEN-EYE

TECHNICAL SPECIFICATIONS RAVEN-EYE® The RAVEN-EYE® is a universal non-contact level/velocity flow sensor that can be connected to the RTQ flow logger series or the UNI-TRANSTM monitor & transmitter. Optionally it can also be connected to any device using the Modbus ASCII communication protocol. Velocity Measurement Method Radar Range ±0,15 to ±9 m/s (bi-directional) Accuracy ± 0,5%, + zero stability Zero Stability ± 0,02 m/s Resolution 0,001 m/s Optional Combined Level Measurement (Ultrasonic) Method Ultrasonic pulsed echo Range 0,25 to 2,00 m (with ULS-02) 0,25 to 6,00 m (with ULS-06) Accuracy ± 1% of reading, + zero stability Includes non-linearity, hysteresis and temperature effects for US Zero Stability ± 2 mm Resolution 1 mm Optional Combined Level Measurement (Radar) Method Radar Range 0,01 to 15 m Accuracy ± 2 mm of reading Resolution 1 mm Optional Separate Level Measurement Method: Any 4-20 mA loop powered sensor Flow Measurement Method: Conversion from surface velocity measurement to average velocity based on patent pending self learning model using velocity distribution measurements. Conversion of water level and pipe size to fluid area. Multiplication of fluid area by average velocity to obtain the flow rate. Conversion Accuracy: ±5.0% of reading Assumes pipe is 0 to 90% full Communication RS-485 communications port with Modbus ASCII slave communication protocol RAVEN-EYE® New Generation Open Channel Non-Contact Radar Velocity Sensor 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 self-learning 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 custom-tailored 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.
