UNSPSC 41112502: Rheometers

UNSPSC 41112502 Rheometers is a Commodity code that covers instruments for measuring the flow properties and viscosity of fluids and gases, but state and local opportunities posted under this code show minimal alignment with its nominal scope. The recent opportunities tagged to this code actually span atmospheric monitoring equipment for water and wastewater facilities, gas flow calibrators for environmental compliance, mass flow terminals for air monitoring networks, and well-plugging services—none of which constitute rheometry. Water utilities including Collier County, the City of Tampa, and the City of Phoenix Water Services have solicited single-source procurements and competitive bids for flow measurement devices, level controllers, and gas detection sensors used in treatment process control and SCADA integration. A state environmental agency, the Texas Commission on Environmental Quality (TCEQ), has issued multiple bids for specialized calibration and flow measurement equipment. The Solid Waste Authority of Palm Beach County and Dane County have also posted opportunities related to waste-energy and renewable-gas facilities involving process instrumentation. The code shows fragmented issuing-body participation across water utilities, county waste management, and state environmental divisions.

Recent activity concentrates in Florida and Texas, with secondary signals in Arizona, Wisconsin, and California. The Solid Waste Authority of Palm Beach County posted a mass-burn waste-to-energy facility RFEI (Request for Expressions of Interest) due November 18, 2026, seeking Demolition, Design, Build, Operate and Maintain (DDBOM) services including process equipment and instrumentation. Collier County issued a Notice of Intent to Single Source Gilson Engineering Sales, LLC for Siemens process instrumentation products and services (three-year term, October 2026 start), and the City of Tampa posted an Intent to Single Source for Emerson-Flexim clamp-on flow measuring devices from CL2 Solutions due August 26, 2026, with an estimated 12-month cost of $30,000. The City of Phoenix Water Services Department solicited atmospheric monitoring instruments for fixed installations under IFB-27-0435 (five-year contract, proposals due September 4, 2026) with DBE-Neutral program requirements. TCEQ solicited gas flow calibrators (proposals due July 7, 2026) and a mass flow terminal (proposals due March 31, 2026) for air monitoring calibration. Eastern Municipal Water District in California requested proposals for meter verification, calibration, and repair services due July 15, 2026. The code shows little substantive recent activity directly aligned with rheometer procurement.
