The Workhorse Proteus from Teledyne RD Instruments is an acoustic Doppler current profiler (ADCP) for collecting current, wave, flow, transport, and discharge data in oceans, estuaries, and rivers. Its Advanced Doppler Sonar Platform supports flexible pinging and sampling schemes, while the Catalyst Processor handles data processing, logging, and communication with other electronics.
Proteus uses four angled beams for current profiling and a fifth, vertical beam for direct measurement of vertical velocity. Its narrow beamwidth supports precise velocity measurements, while an attitude and heading reference system (AHRS) and dynamic bin mapping improve orientation compensation. Serial and Ethernet interfaces support integration with survey and monitoring systems.
