Rosemount 8800 Reducer Vortex Flow Meter – 1" (DN25)

Model: 8800DR010SA3E7D1I8A75HR7Q5Q8Q66Q70Q77

• Flanged vortex flow meter with reducing flanges integrated into the design
  
• Reduces cost by eliminating the need for field assembly of reduced piping
  
• Both reducer and standard vortex have a common face-to-face dimension which
  
• Available with 1 inch through 14 inch (25 mm through 350 mm) line sizes

Key Features

• Integrated Reducer Design (Built-In, Not Bolted-On)
  Accurately measures lower flow rates without needing separate reducers or pipe modifications
• Extended Low-Flow Measurement Range
  The reducer design can double the measurable low-end flow range, making it ideal for variable or low-load processes
• Lower Installation Cost & Risk
  Eliminates field welding and piping adjustments → faster installation and fewer errors
• Same Face-to-Face Dimensions as Standard 8800
  Drop-in replacement without changing piping layout—engineers love this part
• Gasket-Free, Non-Clog Design
  No impulse lines or crevices → reduced leak points and maintenance
