UNSPSC 41112407: Liquid level controls or instruments

UNSPSC 41112407 Liquid level controls or instruments is a Commodity code covering sensors, controllers, interface boards, and monitoring equipment deployed in water and wastewater systems, utility infrastructure, and industrial facilities. State and local governments soliciting under this code include city water services departments, utility authorities, and municipal procurement offices. The work being bought spans fixed atmospheric and liquid-level monitoring equipment with associated control modules, interface boards, alarm systems, and calibration materials, as well as installation, commissioning, training, and ongoing maintenance support. Recent solicitations show purchasing agents requesting controllers and interface boards for SCADA systems, advanced HMI equipment, and hazardous-gas detection sensors with 48-hour replacement-parts availability requirements and multi-year service terms.

Recent opportunities cluster in Florida and the Southwest. The City of Tampa has posted two RFQs within the past two weeks—RFQ 27-P-00018 (due October 29, 2026) for 25 phase-monitor controllers, 15 interface boards for SCADA ACE3600 mixed I/O modules, and 15 duplex lift-station backup pump controllers, all with five-business-day delivery requirements; and RFQ 26-P-00515 (posted October 8, 2026, deadline passed) for three Advanced HMI 15" units. The City of Phoenix Water Services Department issued IFB-27-0435 (due September 4, 2026) for fixed atmospheric monitoring instruments detecting hydrogen sulfide, methane, oxygen, chlorine, and other hazardous gases, with a DBE-N participation requirement and five-year contract term. The City of Gallup, New Mexico released an RFP for a comprehensive SCADA system upgrade affecting 46 water-distribution locations (posted June 29, 2026), requiring fiber optic VLAN backbone implementation, 900 MHz and 450 MHz radio replacement, and New Mexico resident business preferences (8–10 percent) if certified. The Solid Waste Authority of Palm Beach County's waste-to-energy facility RFEI (due November 18, 2026) falls outside the code's nominal scope and represents an unrelated tagging.
