About this opportunity
The National Institute of Standards and Technology seeks seven ultrasonic flowmeters and associated equipment for replacement on the National Bureau of Standards Reactor cooling systems, with proposals due September 4, 2026. This is full and open competition with no set-aside; award will be made to the lowest-priced, technically acceptable offeror.
Place of performance is Gaithersburg, Maryland. The procurement requires new, commercial off-the-shelf equipment meeting firm technical specifications: each meter must cover 0–6000 GPM with a minimum 50:1 turndown ratio, 2% total error of reading (1% accuracy above 1 FPS), isolated 4–20 mA analog output with 0.1% loop accuracy, and capability for secure digital communications via Modbus/Ethernet. Equipment must operate on 4" and 12" diameter Schedule 80 aluminum primary cooling pipes and Schedule 40 steel secondary cooling pipes without pipe breach, function at process fluid temperatures no higher than 114 degrees Fahrenheit and pressures no higher than 10 psia, and accommodate primary cooling water that is heavy water (purified) and secondary cooling water with minimal solids and some expected algae. All units must include permanent Windows-compatible software licenses, IEC 61326-1 Certificates of Conformance, installation/operation/maintenance manuals, interface cables, and manufacturer warranty. Power is 120VAC 60 Hz (preferred) or 24 VDC. Delivery is F.O.B. Destination within four months from award. The solicitation incorporates cybersecurity requirements addressing FISMA, OMB Circular A-130, and FIPS Publication 200, including system security plans, access controls, multifactor authentication, vulnerability scanning, encryption at TLS 1.2 or better with FIPS 140-2/140-3 validation, and incident response procedures. NAICS code 334516; PSC 6640. Quotations must be submitted in three volumes (Technical, Price, and Terms and Conditions) with price valid for 90 days from submission. The Government reserves the right not to award and to award without discussions.

Amendment 1to RFQ 1333ND26QNB610465
Clarification questions:
Vendor Question 1:
Could you please confirm the solids content (TSS) of the water? If this is clean water, with less than 2% TSS, please let us know so we can determine the appropriate unit for the application.
NIST Response:
This water is moderately clean, not a slurry (2% TSS is closer to wastewater) but not filtered
Vendor Question 2:
The factory has confirmed that no software is required to configure the meter, as very few ultrasonic meters require software for configuration.
NIST Response:
PC-based data logging is a nice-to-have but not a necessity.
Vendor Question 3: (clarification on the following process conditions for the primary and secondary cooling systems)
Operating temperature of the process fluid (or pipe surface temperature) at the measurement points, for both the primary and secondary cooling loops. This determines whether standard or high-temperature transducers are required.
NIST Response:
No higher than 114 degrees Fahrenheit.
Vendor Question 4: (clarification on the following process conditions for the primary and secondary cooling systems)
Operating pressure of the cooling water at the measurement points (primary and secondary).
NIST Response:
No higher than 10 psia.
Vendor Question 5: (clarification on the following process conditions for the primary and secondary cooling systems)
Confirmation of the process fluid — the SOW references cooling water; please confirm it is treated water with no significant entrained solids or aeration that could affect ultrasonic signal transmission.
NIST Response:
Primary – Heavy water, purified. Secondary - Water with minimal solids. Some algae to be expected but not significant.
