About this file
This specification document outlines the Bureau of Land Management's (BLM) requirements for one Acoustic Doppler Current Profiler (ADCP) system to be delivered to Taos, NM by August 1, 2025. The system must include a portable acoustic Doppler profiler for floating platform use in medium depth streams, a dive-resistant measuring platform for shallow streams up to 5.0 m/s velocities, power and communication cables, power supply, hard-shell shipping case, and Windows software for real-time display capabilities.
The technical specifications require velocity measurement profiling ranges of 0.06m to 40m distance and ±20 m/s velocity, with ±0.25% accuracy. The system must have 5 or 9 transducers in a 4 beam/4 dual beam Janus configuration, operating at 1.0-3.0 MHz and 0.5-1.0 MHz frequencies. Additional requirements include a temperature sensor (±0.1°C accuracy), solid-state compass/tilt functionality, 8GB internal memory, 50m waterproof depth rating, and 8-hour continuous operation capability without GPS. The solicitation (140L4025Q0004) is a total small business set-aside under NAICS 334513, with quotes due February 3, 2025.

BUREAU OF LAND MANAGEMENT (BLM)
ACOUSTIC DOPPLER CURRENT PROFILER (ADCP)
SPECIFICATION DOCUMENT
The BLM has a requirement to procure one (1) Acoustic Doppler Current Profiler (ADCP) system.
Requirements: (1) portable acoustic Doppler profiler/discharge measurement system for use on a floating platform in medium depth streams. (1) An ADCP compatible dive resistant measuring platform suitable for shallow streams in velocities up to 5.0 m/s, with a soft carrying case suitable for rugged field applications. (1) power cable, wet pluggable 9-pin D-sub-RS232 communication cable, power supply, and hard-shell shipping case. (1) Windows software capable of real-time display of current profiles, bottom tracking, water depth, and discharge measurement. The ADCP must support DBPS/RTK GPS interface for geo-referencing and sound speed corrections as an integrated or expandable functionality.
Specifications: The ADCP unit shall meet the following government specifications:
