3051CFC Compact Conditioning Orifice Plate Flow Meter

Brand: Rosemount
Request Information
Providing precise flow measurements, the Rosemount 3051CFC Compact Conditioning Orifice Plate Flow Meter is an industry-leading solution designed with a compact conditioning orifice plate. 

This conditioning plate has a patented 4-hole design which enables accurate measurement downstream of flow disturbances.

This conditioning orifice plate also reduces pipe straight run, requiring only two pipe diameters (2D) upstream and downstream for installation in tight areas.
Features
  • Patented 4-hole orifice plate design enables accurate flow measurement near upstream flow disturbances.
  • Complete flow assemblies are leak-tested and calibrated to reduce leak points up to 70% and simplify installation
  • 10-year stability and 8:1 flow turndown (150:1 rangedown) produce reliable measurements and application flexibility
  • Innovative orifice plate requires only 2D upstream and downstream to reduce pipe straight-run requirements
  • Local operator interface offers easy-to-use menus and built-in configuration buttons for streamlined commissioning
  • Loop Integrity diagnostics detect electrical loop issues for reduced downtime
  • SIL 2/3 certified to IEC 61508 (via 3rd party) and prior-use certificate of FMEDA data for safety installations
