Emerson Introduces New Rosemount Orifice Plate Flow Metering Technology
Needing minimal straight pipe-run, patent-pending design installs downstream of disturbances, and conditions flow profile for stable, accurate measurement

CHANHASSEN, MN (August 30, 2004) — Emerson Process Management revolutionizes flow metering again with the next generation of orifice plate technology. Rosemount Conditioning Orifice Plate products deliver ±0.5% accuracy with only two diameters of straight pipe-run. This patent-pending design makes orifice metering more flexible and better than ever before.

The Rosemount 405 Compact Conditioning Orifice Plate and 1595 Conditioning Orifice Plate enable users to extend the use of orifice plates into measurement points previously limited by existing piping configurations. These products deliver accurate and repeatable results downstream of a variety of flow disturbances that normally cause swirl in the flow process. Rosemount Conditioning Orifice Plate technology consists of four equally spaced holes that condition the flow profile for a more stable, accurate measurement. This unique design is the highest performing primary element available.

Rosemount Conditioning Orifice Plates require less straight run, significantly reducing material, labor and procurement costs. These devices can be installed virtually anywhere. The Conditioning Orifice Plate offers an economical way to retrofit installations that have experienced poor results caused by limited straight-run.

Integrating the new Conditioning Orifice Plate primary with Rosemount transmitters as a flowmeter provides a more cost-effective and reliable measurement. The unit arrives assembled, configured, and ready to install. The 3051SFC Flowmeter combines the new Compact Orifice design with the scalable architecture of the Rosemount 3051S transmitter. This flowmeter provides advanced software capability, including user configured flow units, low flow cut-off and customized process alerts. Installation flexibility is greatly improved because users are able to install their flowmeter directly in the process piping and position their display and communication ports at grade level.

The Rosemount 3095MFC Mass Flowmeter integrates the Compact Orifice primary with the 3095 MultiVariable™ transmitter. This flowmeter enables accurate, compensated mass flow output by measuring differential pressure, pressure, and temperatures with a single device. This flowmeter is ideal for gas and steam applications where a compensated flow output is required.

The 3051SFC and 3095MFC are part of Emerson's broad range of intelligent, digital field devices that power the PlantWeb® digital plant architecture to improve plant efficiency by 2% and more through delivering asset optimization, process automation, and management execution. Further cost savings, increased plant availability, and enhanced safety and environmental compliance are achieved when the flowmeters are integrated into the PlantWeb architecture.
