About this file
This is a detailed technical specification document from the Bureau of Land Management (BLM) for one Acoustic Doppler Current Profiler (ADCP) system. The system must include a portable acoustic Doppler profiler/discharge measurement system for floating platforms in medium depth streams, an ADCP-compatible dive resistant measuring platform for shallow streams with velocities up to 5.0 m/s, necessary cables and cases (power cable, RS232 communication cable, power supply, hard-shell shipping case), and Windows software for real-time display capabilities.
The specifications outline precise technical requirements including velocity measurement capabilities (0.06m to 25m profiling range, ±20 m/s velocity range, ±0.25% accuracy), transducer configuration (5 or 9 transducers with 4 beam/4 dual beam Janus configuration), depth measurement specifications (0.2m to 80m range), temperature sensing (±0.1°C accuracy), and additional features like compass/tilt functionality and 8Gb internal memory. The system must be waterproof rated IP 68 minimum and operate between -5°C to 45°C. Delivery is required by August 1, 2025, to the BLM office in Taos, NM, with FOB Destination terms.
