Rosemount™ 2051CFA Annubar™ Flow Meter

The Rosemount 2051CFA Annubar Flow Meter delivers accurate flow and pressure via a single pipe penetration.

Featuring industry-standard performance, the Rosemount 2051CFA Annubar Flow Meter provides dependable flow measurements via mulitple communication protocols including WirelessHART® technology. The patented Annubar sensor design is able to deliver accuracy over a wide flow range, maintain a small profile in the pipe, and provide flow and pressure measurements via a signal pipe penetration. This safety-certified flow meter is engineered with a local operator interface (LOI) for field commissioning.

Key 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
  • T-shape design of averaging pitot tube ensures very low permanent pressure loss
  • Local operator interface offers easy-to-use menus and built-in configuration buttons for streamlined commissioning
  • Sensor stagnation zone positioned to reduce noise, measurement inaccuracies and keeps particulates from clogging
  • SIL 2/3 certified to IEC 61508 (via 3rd party) and prior-use certificate of FMEDA data for safety installations
  • WirelessHART® technology is secure, cost-effective and delivers >99% data reliability
  • SmartPower™ module provides up to 10-year maintenance-free operation and field replacement without transmitter removal
