3051CFA Annubar Flowmeter

Brand: Rosemount
Request Information Favorite
An industry-leading flow measurement solution, the Rosemount 3051CFA Annubar Flow Meter is customized with a patented T-shaped, averaging pitot tube that features reliable accuracy over a wide flow range. 

This patented sensor design maintains a small profile in the pipe for reduced permanent pressure loss and is capable of flow and pressure measurements via a single pipe penetration.

This flow meter is also leak-tested and calibrated to reduce leak points for increased process control.
Features
  • Patented T-shape Annubar Creates a Fixed Separation Point for DP Signal Improvement Over a Wider Flow Rate
  • 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
  • Sensor Stagnation Zone Positioned to Reduce Noise, Measurement Inaccuracies and Keeps Particulates From Clogging
  • 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
