Emerson Releases Brand New Flow Meter With Quadruple Sensors and TransmittersSeptember 23, 2020 by Alessandro Mascellino
The Rosemount 8800 Quad Vortex flow meter is one of the first in the industry with quadruple sensors and transmitters.
Developed to meet safety integrity level requirements, the meter provides a compact flow solution with built-in redundancies without the need for intentional leak points.

The Rosemount 8800 is first and foremost a flow measurement solution designed to guard against spurious trips by utilizing two out of three votings and including a fourth integrated transmitter for process control. The device has an accuracy rating of ±0.65% of the volumetric rate for liquids and ±1% of the volumetric rate for gas and steam.
Featuring a 15:01 turndown, the meter has an output of 4-20 mA with HART 5 or 7 or 4-20 mA with HART 5 or 7 and scalable pulse output. Flanges are available in various facings, but Emerson already provides variants following the ANSI Class 150 to 1500, DIN PN 10 to PN 160, and JIS 10K to 40K.

The Rosemount 8800 Quad Vortex has operating temperatures between -330 °F and +800°F (–201°C and +427°C), and line size of 2 to 12-in, 50 to 300 mm.
Introducing Quadruple Sensors and Transmitters
Made of multiple independent sensors placed within an all-welded meter body, the meter reduces piping needs threefold. The flow meter also features an isolated sensor allowing for inline replacement without breaking the process seal.
Its CriticalProcess valve (CPA option) provides an extra level of safety assurance by allowing users to verify secondary containment integrity. The addition of a mass balanced sensor and Adaptive Digital Signal Processing with visual filtering allows the meter to achieve vibration immunity.
The Rosemount 8800 is IEC 61508-certified for safety instrumented systems up to SIL 3 with 2oo3 voting. All pairings between sensors and transmitters are independently calibrated and given a unique calibration number called a reference k factor.
Designed for Space-Saving Piping Applications
The Rosemount 8800 is built to meet measurement challenges in chemical, power, refining, and offshore oil and gas applications. Within these fields, the flow meter built for applications where space is limited, and safety is crucial, where multiple individual flow meters would be needed in a small space.
The new flow meter from Emerson performs as well as four separate meters, without needing impulse lines that might clog. This way, the meter saves money by reducing installation costs and integrating multiple devices into a simple all-in-one drop-in solution.

“Our refining and chemical customers who have tested this new flow meter have found tremendous value from this unique and differentiated flow solution,” commented Julie Valentine, refining industry flow solutions director for Emerson’s Automation Solutions business.
“The 8800 Quad Vortex flow meter has made the specification, purchase, and installation of a SIS/SIL application with reduced piping and space requirements easier than ever before.”
The flow meter is already available on Emerson’s site, and you can check its data-sheet.
