Rosemount™ 3051SFC Compact Annubar™ Flow Meter
Northeast Controls is pleased to be the authorized Emerson representative to sell this product line for Municipal Water and Wastewater applications, and as part of an overall Integrated Solution for all applications and industries.
rosemount 3051sfc compact annubar flow meter
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.
