Rosemount™ 3051SFA Annubar™ Flow Meter

The Rosemount 3051SFA Annubar Flow Meter is a no-equal solution with a patented, averaging pitot tube that delivers superior measurement accuracy over a wide flow range. This flow meter can measure multiple variables and is engineered with an integrated thermowell for temperature measurement. Its patented T-shaped sensor is capable of obtaining measurements via a single pipe penetration while maintaining a small profile in the pipe to reduce permanent pressure loss and increase energy savings.
