The document outlines the specifications for a Current Profiling System intended for discharge measurements in rivers and streams. The core components include a portable Broadband Acoustic Doppler Current Profiling (ADCP) system enhanced with a Real-Time Kinematic (RTK) GPS positioning system, a flotation platform, and necessary accessories. The ADCP must possess capabilities such as bottom tracking, wide coverage depth (0.1 to 6 m), built-in compass, a 5-beam configuration operating at 3 MHz, and a sampling frequency of at least 1 Hz. Key features include a velocity measurement range of +/- 5.0 m/s, the ability to measure multiple water column cells, integrated temperature, and tilt sensors, and robust Bluetooth communication. The equipment should ensure at least 7 hours of operation on a rechargeable battery and have a waterproof rating of IP67. A compatible RTK GNSS system with necessary components for enhanced positioning is also required, along with a flotation platform and custom carrying case. This document serves as part of a government RFP aimed at acquiring an advanced water measurement system, emphasizing accuracy, portability, and durability, pivotal for environmental monitoring and management initiatives at various governmental levels.
