Rosemount™ 3051CFC Compact Annubar™ Flow Meter

Rosemount

The Rosemount 3051CFC Compact Annubar Flow Meter is an industry-leading flow measurement solution with an averaging pitot tube. This flow meter has been leak-tested and calibrated to reduce leak points and simplify installation. The patented, T-shaped sensor has a flat upstream surface for high performance over a wide flow range and is engineered to install between raised-face flanges to eliminate the need for impulse piping and additional process penetrations.
