Rosemount™ 2051CFC Compact Conditioning Orifice Plate Flow Meter

Rosemount

The Rosemount 2051CFC Compact Conditioning Orifice Plate Flow Meter is an industry-standard solution for reliable flow measurements. With a patented, 4-hole design, the compact conditioning orifice plate of this flow meter ensures dependable data downstream of disturbances and requires only two pipe diameters (2D) upstream and downstream for a reduced pipe straight run. This flow meter also features a local operator interface (LOI) for easy field commissioning.
