Rosemount 8800 Reducer Vortex Flow Meter

The Rosemount 8800 Reducer Vortex Flow Meter combines the reliable electronics, sensor, and meter body of the renowned Rosemount 8800 Series with integral reducers, offering accurate flow measurement at lower flow rates. This smart design eliminates the need for field assembly and welding of separate reducers and piping, reducing installation costs and project risks. Additionally, the face-to-face dimensions of the Rosemount 8800 Reducer match those of the traditional 8800 Series, providing unparalleled versatility for a wide range of applications.

Key Features

• Improve low flow rate measurement performance with an integrated reducer design.

• Simplify installation and reduce project risks with built-in reducers that eliminate field assembly and welding.

• Maintain flexibility in installation with the same face-to-face dimensions as the traditional Rosemount 8800 meters, allowing easy meter sizing without changing piping.

• Enable online sensor replacement without breaking the process seal with an isolated sensor.

• Enhance plant availability and reduce potential leak points with a unique gasket-free meter body design.

• Ensure additional safety with the CriticalProcess valve (CPA option), which allows verification of secondary containment integrity.

• Achieve vibration immunity with a mass-balanced sensor and Adaptive Digital Signal Processing with visual filtering.

• Simplify electronics verification with a standard internal signal generator included in every meter.

• Reduce maintenance costs and downtime with no moving parts that require repair or replacement.
