Description
Teledyne RD Instruments’ Workhorse Horizontal Acoustic Doppler Current Profiler (H-ADCP) is an acoustic monitoring system that “looks” out horizontally from its mounting structure to measure near-surface water currents and optional multi-directional waves. This unique instrument utilizes Teledyne RDI’s Broadband signal processing to obtain an optimal combination of range, resolution, and data quality which cannot be obtained using narrowband products. The Workhorse H-ADCP measures currents at 128 individual points at up to 200 meters horizontal range, providing a detailed illustration of the complete flow structure centered at a single depth. The 300 kHz H-ADCP can be upgraded to add wave height and direction capabilities, fulfilling all your monitoring needs.
