UNSPSC 41112501: Flowmeters

UNSPSC 41112501 Flowmeters (Commodity) covers flow measurement and calibration equipment that state and local governments procure for air quality monitoring, water system management, and wastewater collection operations. Recent solicitations show state environmental agencies and municipal water districts buying specialized gas flow calibrators with NIST traceability, mass flow terminals for laboratory calibration, and flow monitoring systems for collection networks—equipment that must integrate with existing infrastructure and meet EPA or equivalent compliance standards. The work ranges from equipment procurement with factory calibration and warranty to multi-year service contracts encompassing installation, maintenance, remote monitoring, and quarterly reporting. Issuing bodies include state environmental protection agencies (Texas Commission on Environmental Quality, Illinois EPA), municipal water and wastewater districts (Eastern Municipal Water District, City of Nashua), and county governments (Riverside County).

Texas dominates recent activity under this code. The Texas Commission on Environmental Quality posted two solicitations within the past two months: an RFB for gas flow calibrators (due July 7, 2026) specifying Mesa Metrology equipment with NIST traceability and one-year manufacturer warranty, and an earlier RFB for a mass flow terminal (Fluke Electronics Molbox2-A700K or equivalent, due March 31, 2026) serving as a primary calibration standard for air monitoring networks. The City of Nashua, New Hampshire issued an IFB for wastewater collection system flow monitoring (due June 10, 2026) requiring seventeen flow monitors, three rain gauges, real-time monitoring, remote notification, and three years of maintenance through June 30, 2029, with a mandatory pre-bid meeting on May 27, 2026. Eastern Municipal Water District (California) is requesting proposals for meter verification, calibration, and repair services (due July 15, 2026). Riverside County, California issued a competitive bid for Cla-Val parts inventory (due February 13, 2026). Texas bidders can claim preferences under state rules based on Texas residency, veteran ownership, or economically depressed area sourcing, though no set-asides are imposed. All procurements require F.O.B. destination pricing, manufacturer documentation or equivalency certification, and compliance with state certifications including non-boycott of Israel and Iran exclusions.
