Rosemount™ 3051SFA Wireless Annubar™ Flow Meter
rosemount 3051sfa wireless annubar flow meter
The Rosemount 3051SFA Wireless Annubar Flow Meter is a cost-effective, best-in-class MultiVariable solution that provides measurements via a secure WirelessHART® network.
This flow meter delivers direct variable measurements without the cost of wiring and is built with a patented averaging pitot tube designed for optimal accuracy over a wide flow range. This T-shaped Annubar sensor also maintains a small profile in the pipe for reduced permanent pressure loss and increased energy savings.
