Four-in-one compact flow meter

02 October 2020

Emerson has introduced the Rosemount 8800 Quad Vortex flow meter which has been designed to meet stringent safety standards in environments and applications that require safety instrumented systems (SIS).

The flow meter is said to be the first in the industry with quadruple sensors and transmitters to meet SIL requirements. Comprised of multiple independent sensors in an all-welded meter body, the meter provides a compact flow solution with built-in redundancies for added safety without introducing intentional leak points. The meter reduces piping needs threefold by eliminating the additional flanges and pipe runs required for the installation of multiple flow meters in a redundant flow measurement solution.

With the ability to meet measurement challenges in industries such as chemical, power, refining, and offshore oil and gas applications – particularly where space is limited and safety is crucial – the Rosemount 8800 Quad Vortex flow meter can take the place of multiple individual flow meters. It can accomplish the same task as four separate meters, without needing impulse lines that might clog. The meter is said to offer cost savings through reduced installation costs as it offers a simple all-in-one drop-in solution.

The design and configuration of the flow meter allows for a SIL 3-capable solution and protects against spurious trips using a two out of three (2oo3) voting method. The 2oo3 voting method ensures that at least two of the sensors must read ‘good’ for a process to continue, which means one poor reading does not trip a complete process shutdown.
