UNSPSC 41112512: Flow computers or totalizers

UNSPSC 41112512 Flow computers or totalizers, a Commodity code, covers gas flow measurement, calibration, and verification equipment that state and local governments procure to maintain laboratory and field monitoring networks. State and local buyers under this code are primarily environmental and water utilities acquiring specialized flow measurement hardware, calibration systems, and related analytical instrumentation to meet EPA compliance requirements and support air and water quality monitoring programs. Recent solicitations name state environmental agencies, regional water districts, and county governments as primary issuing bodies.

Activity under the code concentrates in Texas and Illinois, with California and Florida also posting recent opportunities. The Texas Commission on Environmental Quality (TCEQ) Air Monitoring Division has issued multiple RFBs in the past two months: RFB 582-26-15780 (posted June 30, 2026, due July 7, 2026) seeks Mesa Metrology Series ML-800 gas flow calibrators with multiple flow cells to maintain NIST traceability for EPA gas verification protocols, with deliveries required within 60 calendar days to TCEQ's Austin facility; RFB 582-26-15424 (posted May 27, 2026, due March 31, 2026) procures a Molbox2-A700K mass flow terminal by Fluke Electronics (Part #6074904) or equal to serve as a primary flow standard for TCEQ's calibration laboratory. Eastern Municipal Water District (EMWD) in Riverside County, California issued RFP3856 (posted June 9, 2026, due July 15, 2026) for meter verification, calibration, certification, preventative maintenance, and repair services across its service territory. The Illinois Environmental Protection Agency posted a sole-source procurement for Sabio Environmental zero air generators valued at $59,100.00 (posted March 12, 2026, due March 20, 2026). Texas bidders may claim state preferences under 34 TAC Rule 20.38 for Texas bidder status, service-disabled veteran ownership, or economically depressed area sourcing; Illinois and California procurements follow state small-purchase and competitive-bidding rules. All equipment must meet stringent technical specifications, maintain manufacturer warranties, and comply with federal environmental standards.
