UNSPSC 41112503: Rotameters

UNSPSC 41112503 Rotameters is a Commodity code that encompasses flow measurement and monitoring instrumentation procured by state and local water utilities, environmental agencies, and waste facilities to measure, calibrate, and verify fluid and gas flows in treatment processes, monitoring networks, and industrial operations. State and local governments buy rotameters and related flow-measuring devices as components of larger process control systems, often integrated with SCADA infrastructure or standalone atmospheric and water quality monitoring installations. The issuing bodies span water and wastewater departments within cities and counties, state environmental agencies, special-purpose water districts, and county waste management authorities. Recent solicitations show water utilities and environmental monitoring divisions are the primary buyers, with repeat activity from Florida water and wastewater systems (Collier County, City of Tampa) and multi-jurisdictional agencies such as the Texas Commission on Environmental Quality.

Activity under the code concentrates in Florida, Texas, Wisconsin, Arizona, and California, driven by water treatment facility upgrades, waste-to-energy projects, and atmospheric monitoring network maintenance. Representative recent opportunities include Collier County's notice of intent to single-source Siemens Process Instrumentation products including flow meters and level sensors for water and wastewater SCADA integration (PUR17875, challenge period closed October 1, 2026); the City of Tampa's sole-source procurement of Emerson-Flexim clamp-on flow measuring devices for the David L. Tippin Water Treatment Facility at an estimated 12-month cost of $30,000 (26X01679, objection deadline August 26, 2026); the City of Phoenix's IFB for atmospheric monitoring instruments including gas sensors and calibration equipment at water and wastewater facilities (IFB270435, offers due September 4, 2026); the Texas Commission on Environmental Quality's bid for gas flow calibrators including Mesa Metrology Series ML-800 base units and flow cells (RFB 582-26-15780, bids due July 7, 2026); and Eastern Municipal Water District's RFP for meter verification, calibration, certification, and repair services (RFP3856, proposals due July 15, 2026).
