Rosemount™ 8800 Quad Vortex Flow Meter
The Rosemount 8800 Quad Vortex provides the ultimate redundant flow measurement solution to guard against spurious trips using two out of three voting and includes a fourth integrated transmitter for process control.
The 8800 Quad 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 shedder bars, quadrupole sensors and sensing elements, and quadrupole transmitter configuration provides the ultimate solution for redundant flow measurement
  • IEC 61508 certified for use in safety instrumented systems up to SIL 3 with 2oo3 voting
  • An isolated sensor allows for inline 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
  • 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 sensor/transmitter pairings are independently calibrated and are given a unique calibration number called a reference k factor
