About this file
This document is a Salient Characteristics specification for an Acoustic Doppler Current Profiling (ADCP) System. The specification details requirements for a highly precise underwater measurement system with two primary components: a main ADCP system and a pulse-coherent mode functionality. The ADCP system must have a three-beam configuration with a right-angled head, operational acoustic frequency of 2 MHz, water velocity profiling capabilities up to 10 m, and internal sensors for temperature, compass, tilt, and pressure. Additional technical specifications include a 12 VDC power source, 16 GB internal data storage, RS422 communication, a compact housing (80 mm diameter x 634 mm long), and a depth rating of 500 m.
The pulse-coherent mode component adds advanced measurement capabilities, including velocity profiling up to 4 m, user-selectable cell sizes between 0.01-0.13 m, a minimum blanking distance of 0.1 m, and the ability to handle 256 cells. The system must operate in temperatures from -5 to 40°C, include a 5 m serial cable with a specific connector, and be shipped in a protective crate. The comprehensive specifications suggest this is a sophisticated scientific or marine research instrument intended for precise water current and environmental data collection.
