Rosemount™ 8800 Quad Vortex Flow Meter

The Rosemount 8800 Quad Vortex offers a redundant flow solution with two-out-of-three voting and a fourth transmitter for control.

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.

Key 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 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 that simplifies electronics verification
  • All sensor/transmitter pairings are independently calibrated and are given a unique calibration number called a reference k factor


Frequently Asked Questions

A: It is a fully redundant solution in a compact design which eliminates the need for additional flow meters and additional straight run, which reduces installation costs. With no impulse lines and a unique all-welded design, leak points are eliminated, and operating expenses decrease significantly. The cost of a false trip can be very expensive in terms of lost production and the cost of restarting the process. The Rosemount Quad Vortex delivers a reliable 2oo3 voting scheme, which keeps the process running until at least two out of the three transmitters respond to a trip simultaneously.

A: Emerson’s Rosemount Quad Vortex Flow Meter is certified for safety instrumented functions (SIFs) capable up to SIL 3. It is commonly used in Safety Instrumented System (SIS) loop applications, where equipment must meet the highest reliability standards while minimizing and/or eliminating unscheduled shutdowns. During the instrumentation decision process, the requirements document typically states what SIL level the product must meet. The Rosemount Quad Vortex was designed to meet reliability specifications while also providing a fully redundant solution to meet certification levels.

A: The Rosemount Quad Vortex is installed in several different industries like chemical, refining and power. In steam measurement where safety is critical and a reliable mass and energy balance is needed, the Rosemount Quad Vortex is utilized for its accuracy and dependability. The Rosemount Quad Vortex has been installed in numerous applications — hydrofluoric alkylation units, delayed coker heaters, feedwater flow in power plants, reformers in chemical plants, and more.

A: For simplified troubleshooting, device diagnostics allow for verification in the field of the flow meter’s electronics and sensor without process shutdown. The flow signal generator built directly into the electronics enables remote verification of the electronics. The sensor strength value is typically used to see the flow signal and provide further information about the filter settings and health of the sensor.

A: With such a simple installation consisting of bolting in, wiring up and turning on, installation time and costs are greatly reduced. As there are no moving parts, no calibration needed in the field, and no maintenance required, both time and money are saved with this solution.
