Rosemount 8800 Reducer Vortex Flow Meters

Product Description

The Rosemount 8800 Reducer Vortex Flow Meter utilizes the trusted electronics, sensor, and meter body of the Rosemount 8800 Series while harnessing the benefits of integral reducers to accurately measure lower flow rates. This design eliminates field assembly and welding of separate reducers and piping, thereby greatly reducing installation costs and project risk. Additionally, the face-to-face dimensions of the Rosemount 8800 Reducer match that of the traditional Rosemount 8800 Series for ultimate versatility.
