UNSPSC 41112413: Differentialpressure gauge

A measurement instrument designed to measure the difference between two pressure sources.

UNSPSC 41112413 Differential pressure gauge is a Commodity code. State and local governments procuring under this code are buying pressure gauges, pressure transmitters, pressure switches, and related process instrumentation for water, wastewater, and waste-to-energy operations. Recent solicitations show that the code encompasses both standalone inventory purchases of pressure gauges (dial sizes, connection types, materials), integrated instrumentation suites bundled with level sensors, flow meters, temperature transmitters, and accessories for SCADA system integration, and authorized distributor agreements for branded equipment lines such as Allen Bradley, Rockwell Automation, and Siemens process instrumentation. The issuing bodies include municipal water and wastewater departments, waste-to-energy authorities, and county utilities. Tampa appears as a repeat buyer across multiple line-item and single-source solicitations; Phoenix Water Services and Collier County Water and Wastewater are also active solicitors.

Recent activity concentrates in Florida and Arizona. The City of Tampa issued an RFQ (26-P-00548) due October 6, 2026 for twenty-four line items of pressure gauges and related equipment from vendors such as Ashcroft and WIKA, with awards on a one-year basis and delivery required within five business days. The City of Phoenix Water Services Department solicited sealed offers under IFB 26-0398, a five-year contract with offers due August 18, 2026, for pressure transmitters, pressure switches, pressure gauges, diaphragm seals, and related accessories from approved manufacturers including Ashcroft, Dwyer, Emerson, Honeywell, and Siemens, with DBE-N small business participation plan requirements and a local stocking distributor mandate for same-day or next-business-day fulfillment. Collier County, Florida issued a Notice of Intent to Single Source Gilson Engineering Sales, LLC for Siemens MultiRanger ultrasonic level controllers, valve positioners, and flow meters integrated into the County's SCADA system at Water and Wastewater facilities, with a three-year term from October 1, 2026 through September 30, 2029, and the single-source challenge period closed October 1, 2026.
