The Rosemount 3051CFC Series compact orifice flow meter is a complete flow monitoring system designed for closed loop control and general purpose monitoring applications. By integrating the 3051C pressure transmitter with the 405 Compact Orifice primary element, Rosemount has created a high performance, direct mount differential pressure flow meter that lowers installed cost by eliminating the need for fittings, impulse tubing, valves, adapters and manifolds.

Designed to be installed between any existing raised-face flanges, the 3051CFC provides straightforward and affordable installation in a complete system which arrives assembled, calibrated, pressure tested, and ready to install. It is ideal for volumetric measurement of relatively clean liquids, while also being suitable for gases and steam.

The 3051C transmitter offers differential, gauge, and absolute pressure measurements with 0.04% reference accuracy, 80:1 turndown, and 0.12% total real-world performance. It utilizes advanced software including 4-20mA HART, Low Power HART, or FOUNDATION fieldbus communication. The coplanar platform provides installation flexibility.

The 405 Compact Orifice follows ASME and ISO corner tap design and is available in standard or conditioning styles, with the 405C requiring only 2 pipe diameters from upstream disturbances. A self-centering ring ensures optimal accuracy. Available for line sizes from 1/2 to 12 inches and pressures to 600# (PN 100) with 5-year stability and 100ms response time, a wide range of options customize the system to nearly any application.
