Rosemount 8800D Vortex Flowmeter 4-Inch 150 ANSI

The Rosemount 8800D Vortex Flowmeter is a high-performance instrument designed for accurate measurement of liquid, gas, and steam flow in industrial applications. Utilizing vortex shedding technology, it provides reliable mass flow, volume flow, and density measurements with minimal pressure loss. Key features include a robust all-welded sensor design that eliminates ports or crevices, reducing leak points and enhancing durability in harsh environments. It offers excellent vibration immunity, high accuracy (±0.75% for liquids, ±1% for gases), and a wide turndown ratio. Advantages over similar products like ultrasonic or turbine meters include lower maintenance needs, no moving parts, and better performance in high-vibration settings. Applications span oil and gas, chemical processing, power generation, and water treatment. Benefits include easy installation with flanged connections, digital communication protocols (HART, FOUNDATION Fieldbus), and advanced diagnostics for predictive maintenance. Drawbacks may include higher initial cost and sensitivity to flow profile disturbances if not installed with sufficient straight pipe runs. This unit, manufactured in 2013, appears in good used condition based on images, with intact flanges and transmitter.
