The US Geological Survey's Grand Canyon Monitoring and Research Center is seeking to procure one density meter and one associated transmitter for measuring suspended-sediment concentration in water. The Request for Quote (RFQ) 140G0125Q0083 will be issued on March 7, 2025, with written quotes due by March 13, 2025, at 9:00 AM EDT.

The contract is set aside exclusively for small businesses and requires delivery of the equipment within 21 days after receipt of order to the Flagstaff, AZ location. The density meter must provide real-time flow and density measurements for pumped slurry and water, with specific technical requirements including a -inch measurement tube diameter, liquid flow accuracy of 0.1%, and liquid density accuracy of 0.005 g/cm3. The equipment should be constructed of stainless steel and capable of computer output. While no incumbent contractor is mentioned, the procurement builds on previous research, including work by the Concessionary of the Rhone River in France. The specific budget range is not disclosed in the solicitation documents, but the procurement is for a single density meter and transmitter to be used in scientific research at the Grand Canyon Monitoring and Research Center.
