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. Its patented T-shaped sensor is engineered with an integrated thermowell, 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. This flow meter is also engineered with built-in flow calculations for fully compensated mass flow measurements and is offered with multiple communication protocols including WirelessHART.
