Rosemount 4051SFA Anubar Flow Meter

The Rosemount 4051SFA Anubar flowmeter is equipped with a pitot tube for averaging velocity, delivering exceptional measurement accuracy across a wide flow range. Its T-shaped sensor features an integrated thermal sleeve, enabling measurements to be taken through a single pipe opening—while maintaining a compact profile within the pipeline to minimize permanent pressure loss and reduce energy consumption. Designed specifically for demanding applications and harsh environments, the Rosemount 4051SFA Anubar flowmeter also boasts Bluetooth® connectivity, simplifying configuration and maintenance tasks while enhancing operator safety. Additionally, its advanced built-in diagnostic capabilities provide you with deeper insights into system performance.
