UNSPSC 81141507: Tank gauge maintenance

Tank gauging is the measurement of liquids in large storage tanks with the purpose of quantifying the volume and mass of the product in the tanks. Using mechanical gauges that required maintenance, repair, and supply of parts. The oil and gas industry generally uses static volumetric assessments of the tank content. This involves level, temperature and pressure measurements.

UNSPSC 81141507 Tank gauge maintenance, a Commodity code, covers the rental, refill, delivery, and maintenance of liquid-storage and process tanks — principally CO2 and cryogenic nitrogen systems, but also including industrial wastewater and potable-water tanks. State and local governments solicit under this code for recurring tank-service contracts (monthly rental and refill) and one-time tank replacement and installation projects. Issuing bodies include county operations departments, municipal water authorities, and higher-education institutions. Collier County, Florida has posted two similar Quick Quote solicitations within the past month, signaling repeat procurement demand for CO2 tank services across multiple aquatic facilities.
