UNSPSC 41112517: Optical flowmeter and accessories

Apparatus for measuring the flow rate of gas, and other flowing materials with the help of an optical laser base probe.

UNSPSC 41112517 Optical flowmeter and accessories is a Commodity code under which state and local governments procure laboratory measurement and calibration equipment—specifically gas flow calibrators, mass flow terminals, zero air generators, and related analytical components used in air quality monitoring, water utility operations, and environmental compliance testing. The work encompasses equipment procurement, meter verification and calibration services, replacement parts for monitoring systems, and maintenance support. Issuing bodies span state environmental protection agencies, municipal water districts, county operations, and local wastewater departments, with standout repeat activity from the Texas Commission on Environmental Quality (TCEQ) Air Monitoring Division and the Illinois Environmental Protection Agency.

Recent activity concentrates in Texas and Illinois. The Texas Commission on Environmental Quality has issued multiple bids for gas flow calibrators (RFB 582-26-15780, due July 7, 2026) and mass flow terminals (RFB 582-26-15424, due March 31, 2026), both requiring NIST-traceable equipment with EPA compliance and one-year warranties delivered within 14–60 days. The Illinois Environmental Protection Agency procured zero air generators valued at $59,100 through sole-source award to Sabio Environmental, LLC (effective March 3, 2026) and replacement Teledyne-API air quality monitoring parts valued at $43,780 (posted March 2, 2026, due March 9, 2026). Eastern Municipal Water District in Riverside County, California is requesting proposals for meter verification, calibration, certification, preventative maintenance, and repair services (RFP3856, due July 15, 2026). The City of Tampa, Florida issued an Intent to Single Source for Yokogawa parts and service for wastewater operations (posted February 25, 2026), and Riverside County posted an RFB for Cla-Val inventory parts (posted January 21, 2026, due February 13, 2026). Texas procurement vehicles permit bidder preferences under state rules based on Texas residency, service-disabled veteran ownership, and economically depressed area sourcing where applicable; Illinois and California procurements include small-business and minority-enterprise goals.
