For superior accuracy, the Rosemount 3051SFC Compact Annubar Flow Meter is a no-equal, multivariable device engineered with built-in flow calculations for direct reporting of fully-compensated mass flow.
This flow meter includes an averaging pitot tube that installs between raised-face flanges, eliminating the need for impulse piping and additional process penetrations. The patented, T-shaped sensor is also designed with a flat upstream surface for high performance over a wide flow range.
