About the company
Primary Flow Signal Inc., a small-business manufacturer based in Cranston, Rhode Island, supplies precision flow measurement hardware and naval stowage components to the Department of the Navy as a prime contractor under total small-business set-asides, with subsidiary work as a subcontractor on deep-submergence systems certification and hardware modification tasks.
The company operates as a Subchapter S Corporation for-profit manufacturer with a focused customer base dominated entirely by the Department of the Navy. Naval Sea Systems Command accounts for eight awards and $10 million in combined potential value (99% of the prime footprint), anchored by a $7.36 million firm fixed-price purchase order awarded January 21, 2025, for Center Cell Access Ports (CCAP) assemblies for Virginia Payload Tube-equipped submarines, with a base quantity of ten assemblies and options for ten additional units through December 31, 2028. Secondary Navy customers include Naval Supply Systems Command (one award, $19 thousand, for tab-locking items awarded March 20, 2024) and a shared services center award in 2022 for venturi flow meters at $13 thousand. A single award from the CDC Pittsburgh ($12 thousand) represents the only non-Navy activity in the source data.
Primary Flow Signal Inc. competes exclusively under total small-business set-asides on its prime work. Recent awards demonstrate capability in export-controlled naval hardware manufacture: the $2.67 million stowage pallets order (awarded June 15, 2026, for Virginia-class submarine infrastructure, completing January 25, 2028) requires Joint Certification Program certification, NIST SP 800-171 DoD Assessment scores, and CMMC Level 2 self-certification; the CCAP contract similarly demands rigorous export-control and precision-manufacturing compliance. A $13.4 thousand order for FWD CROSS machine components (awarded May 24, 2024, completing August 16, 2024) and smaller precision-hardware orders round out the prime portfolio.
On the subcontract side, Primary Flow Signal Inc. delivers deep-submergence systems scope-of-certification installation and removal services and temporary alteration, temporary modification, and carry-on hardware services to American Systems Corporation, with five subcontract awards between February 2024 and March 2025. The vendor places task orders under the Payload Integration into Deep Submergence Systems Hardware and Services vehicle (three task orders) and SeaPort-e (two task orders).
Activity accelerated in 2024 and 2025 after a dormant period—five awards in 2024 following only one award in 2022—with one recompete exposure inside the next twenty-four months (the stowage pallets order, $2.67 million potential value). Combined potential value across all eleven awards stands at $10.1 million, with $8.4 million obligated to date (84% of ceiling).
