RiverRay ADCP - Intelligent River Discharge System A Revolution in Discharge Measurement Go straight to work collecting highly accurate stream and river discharge data with the RiverRay ADCP (Acoustic Doppler Current Profiler). This economical turnkey system comes complete with: the RiverRay ADCP, a custom-designed boat, userfriendly software, and convenient wireless communication - everything you need to begin making precision river discharge measurements. With over thirty years experience delivering acoustic Doppler products, Teledyne RDI’s RiverRay is the culmination of years of technology advances and invaluable customer feedback. From a shallow stream to a raging river, the revolutionary RiverRay delivers the simplicity and reliability your operations require, at a price that won’t break your budget. The RiverRay ADCP utilizes a flat surface 4-beam phased-array transducer. A dedicated fifth beam is used to measure depth. Product Features • Easy of use: Easy to carry, easy to deploy, and easy to operate; just power and go. Intelligent: Automatic adaptive sampling, which quickly provides accurate discharge measurements without the need for user configuration. Versatile: A single instrument can deliver high quality data in environments ranging from a 0.4 m stream to a 60 m deep river. Customizable: A manual override, which allows advanced users the ability to fully customize their system setting as an alternative to auto-adaptive sampling. Superior surface measurements: Interwoven independent and short range measurements improve the discharge computation in your critical surface layer. Fully integrated GPS for geo-referencing. Flat transducer: The sleek phased array transducer design provides reduced size, weight, and flow disturbance. Platform stability: RiverRay’s float boasts reduced drag, causes less flow disturbance, and provides superior handling—even in high water velocities and rough surface.
