Rosemount™ 3051CFA Annubar™ Flow Meter

The Rosemount 3051CFA Annubar Flow Meter offers easy installation and accurate flow measurement for 0.5–1.5 in. lines.

Featuring industry-standard performance, the Rosemount 3051CFA Annubar Flow Meter provides dependable flow measurements via mulitple communication protocols including WirelessHART® technology. 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. Available with a graphical, backlit display, Bluetooth® connectivity, flow specific configuration and enhanced software capabilities designed to access data quickly.

Key Features

  • Patented T-shape sensor with a flat upstream surface offers a fixed separation point for high performance over a wide flow range and a stagnation zone positioned to reduce noise, measurement inaccuracies, and keep particulates from clogging
  • Application specific configuration allows you to transform your pressure transmitter into a flow meter with a totalizer
  • Complete flow assemblies are leak-tested and calibrated to reduce leak points up to 70% and simplify installation
  • 10-year installed stability and 150:1 rangedown produce reliable measurements and wide application flexibility
  • Bluetooth® wireless connectivity unlocks a far simpler process to perform maintenance and service tasks without the need for a physical connection or separate configuration tool
  • The graphical, backlit display allows for easy operation in 8 different languages in all lighting conditions
  • Loop Integrity and Plugged Impulse Line diagnostics detect electrical loop issues and plugged impulse piping before it impacts the quality of the process for increased safety and reduced downtime
  • Quick service buttons offer built-in configuration buttons for streamlined commissioning
  • SIL 2/3 certified to IEC 61508 (via 3rd party) and prior-use certificate of FMEDA data for safety installations
  • Wireless Features
    • WirelessHART® technology is secure and cost-effective and delivers >99% data reliability
    • SmartPower™ module provides up to 10-year maintenance-free operation and field replacement without transmitter removal
    • Easy installation enables quick instrumentation of measurement points without the cost of wiring
