Rosemount 8800

Rosemount 8800 Series Vortex Flow Meters offer world-class reliability with a gasket-free, non-clog meter body that eliminates potential leak points, resulting in maximum process availability and fewer unscheduled shutdowns. The unique design of Emerson’s Rosemount 8800 Vortex Flow Meters features isolated sensors that eliminate the need to break process seals for flow and temperature sensor replacement.
