Rosemount 2051CFA Annubar Flow Meter
Rosemount  2051CFA Annubar Flow Meter
Describe
 Rosemount  2051CFA Annubar Flow Meter

Featuring reliable flow measurements, the Rosemount 2051CFA Annubar Flow Meter is an industry-standard device with a T-shaped, averaging pitot tube. 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.

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
