UNSPSC 41112420: Pressure drop gauge

Equipment that is used when the pressure is lowered to make the pressure condition fit to the experiment.

UNSPSC 41112420 Pressure drop gauge is a Commodity code that encompasses pressure gauges, pressure transmitters, pressure switches, and related process instrumentation equipment purchased by state and local water, wastewater, and industrial facilities for monitoring, control, and process compliance. State and local governments procure these items both as standalone inventory replenishment—individual gauges, transmitters, and switches for replacement and stocking—and as components integrated into larger control system upgrades and facility automation projects. The work ranges from spot purchases of specific gauge types to multi-year framework agreements with authorized equipment distributors that include repair parts, warranty service, and factory support. Issuing bodies include city water and wastewater departments, county utilities, and special-purpose water authorities; the City of Tampa and City of Phoenix Water Services Department appear frequently in recent solicitations. Single-source and authorized-distributor procurements also dominate the code's activity, reflecting the integration of pressure instrumentation into existing SCADA systems and operational compliance requirements.

Recent activity concentrates in Florida and Arizona, with representation from New Mexico. The City of Tampa issued an Intent to Single Source (ISS 27-X-00020) for Allen Bradley and Rockwell Automation products and support services across its Water, Wastewater, and Waste to Energy Departments, with objections due October 14, 2026, and separately solicited inventory gauges by RFQ 26-P-00548 (due October 6, 2026) covering twenty-four line items of pressure gauges and chlorine gauges with delivery required within five business days. The City of Phoenix Water Services Department issued IFB 26-0398 for a five-year pressure and temperature instrumentation equipment contract commencing October 15, 2026, with sealed offers due August 18, 2026, specifying transmitters, pressure switches, gauges, diaphragm seals, and accessories from manufacturers including ABB, Ashcroft, Emerson, Endress+Hauser, Honeywell, Siemens, and VEGA. Collier County, Florida issued a Notice of Intent to Single Source (PUR17875) Gilson Engineering Sales, LLC for Siemens process instrumentation products including pressure transmitters and level sensors integrated with the county's SCADA system at water and wastewater facilities, with a three-year term from October 1, 2026. The City of Tampa also solicited wastewater inventory components—pressure switches and process meters—by ITB 26-P-00425 (bid discount restricted to SLBE vendors, due August 6, 2026).
