Flow Measurement for Fluidized Catalytic Cracker
Increase process uptime and eliminate harmful emissions from measurement leaks
Efficient flow measurement reduces maintenance costs and leaks
Oil refineries tend to experience plugged impulse lines with very hot viscous black slurry oil with catalyst fines in their flow instrumentation at the fractionator bottoms. Plugged impulse lines require flushing which can result in inaccurate measurement and increased maintenance costs. The Rosemount™ 8800 Vortex Flow Meter can reduce the costs of having to flush the impulse lines yearly and prevent plugging with the all-welded, no-clog design.

Product Solutions
Rosemount 8800 Flanged Vortex Flow Meter offers 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 8800 Flanged Vortex is ideal for all applications from general purpose to the most demanding application. The unique design of the 8800 features an isolated sensor that eliminates the need to break process seals for flow and temperature sensor replacement.
- An isolated sensor allows for online replacement without breaking the process seal
- Increase plant availability, decrease maintenance costs, and eliminate potential leak points with a unique gasket-free meter body design
- The CriticalProcess valve (CPA option) provides an extra level of safety assurance by allowing users to verify secondary containment integrity
