UNSPSC 41112423: Pressure altimeter

A meter which measures the altitude by using the pressure difference of atmosphere.

UNSPSC 41112423 Pressure altimeter is a Commodity code that covers industrial control and measurement instruments used in water systems, wastewater operations, and facility management — specifically pressure measurement, switching, and data acquisition components integrated into supervisory control systems. State and local governments procure pressure switches, digital meters, flow control equipment, and related instrumentation to monitor and regulate water distribution, wastewater treatment, and pump station operations. Issuing bodies include cities, counties, and regional water authorities that maintain critical infrastructure. The mix of recent solicitations shows both routine inventory replenishment from municipal wastewater and water departments and larger capital modernization projects requiring integrated SCADA system upgrades with associated instrumentation and controls.

Recent activity spans Florida, New Mexico, and California. The City of Tampa, Florida posted ITB 26P00425 on July 9, 2026, seeking wastewater inventory components including pressure switches and loop-powered process meters, with bids due August 6, 2026 — a sheltered-market procurement restricted to Small Local Business Enterprise certified bidders with a 5% bid discount for evaluation. The City of Gallup, New Mexico released RFP NGWSP on November 21, 2025, for a comprehensive SCADA system upgrade across 46 water system locations, including replacement of pressure control and monitoring equipment over a 180-day implementation period, with proposals due December 11, 2025, and preferences for New Mexico resident and resident veteran businesses. Riverside County, California issued RFB RFB3909 on January 21, 2026, for Cla-Val industrial control parts inventory, with bids due February 13, 2026. These opportunities reflect both baseline consumables purchasing and infrastructure modernization driving demand for pressure instrumentation, industrial controls, and integrated data acquisition capabilities in water and wastewater systems.
