Rosemount 8800D Vortex Flowmeter 4-Inch ANSI 600 Flanged

The Rosemount 8800D Vortex Flowmeter is a high-performance instrument designed for accurate measurement of volumetric and mass flow rates in liquids, gases, and steam applications. This model features a 4-inch (DN100) flanged connection rated for ANSI 600 pressure class, constructed with 316L stainless steel wetted parts for corrosion resistance and durability in harsh industrial environments. It utilizes vortex shedding technology to provide reliable, maintenance-free operation with no moving parts, reducing downtime and operational costs. Key benefits include high accuracy (±0.75% of rate for liquids, ±1% for gases/steam), wide turndown ratio, and integrated temperature compensation for mass flow calculations. Compared to similar products like orifice plates or turbine meters, the 8800D offers lower pressure drop, easier installation, and better performance in vibrating conditions. Drawbacks may include sensitivity to flow profile disturbances, requiring straight pipe runs. Ideal for applications in oil & gas, chemical processing, and power generation. This unit, manufactured in 2015, appears new or surplus based on images, with no visible wear, and includes a digital transmitter for HART communication.
