Product Description
The Rosemount 8800 Dual Vortex provides a redundant flow measurement solution. The 8800 Dual Vortex Flow Meter protects against false trips using one out of two, or two out of two voting. The 8800 Dual 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.
Features:
- Dual sensors, sensing elements, and transmitter configuration provide a compact solution for redundant flow measurement
- IEC 61508 certified for use in safety instrumented systems up to SIL 3 with 1oo2 voting
- 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 Critical Process valve (CPA option) provides an extra level of safety assurance by allowing users to verify secondary containment integrity
- Achieve vibration immunity with a mass balanced sensor and Adaptive Digital Signal Processing with visual filtering
- A standard internal signal generator included in every meter simplifies electronics verification
- All meters are calibrated and are given a unique calibration number
