Emerson Launches Super Duplex Stainless Steel Micro Motion Coriolis Meter

Micro Motion Duplex Stainless Steel Coriolis meters Shanghai, China (July 12, 2011) — Emerson Process Management now offers Micro Motion ELITE high-flow Coriolis meters made from super duplex stainless steel for corrosion Applications and harsh environments. The super duplex stainless steel instrument provides 8”-10” (DN200-250mm) pipe caliber and the pressure rating increases to 2320psi (160bar).

The super duplex stainless steel instrument has the same reliability, accuracy, and turndown ratio as the 316 stainless steel instrument, while also improving corrosion resistance and pressure rating. Super duplex instruments have excellent corrosion resistance (such as formation water) for the often associated high chloride content in the oil field and are particularly well-suited for measuring production media and medium pipeline pressure applications. Due to the presence of corrosive compounds in crude oil, natural gas and other hydrocarbon fluids, it is necessary to use more reliable and more rugged instruments to ensure high-precision measurements over a wide range of measurements.

Micro Motion ELITE High-Flow Coriolis meters provide ±0.10% liquid and volume flow measurement accuracy, plus ±0.35% gas quality measurement accuracy. The high flow Coriolis meters have a density measurement accuracy of ±0.0005 g/cc and can handle a maximum liquid flow of 94,000 lb/min (2,550 tons/hour).

Emerson's Micro Motion Coriolis meters have a design with no moving parts and therefore do not generate wear or measurement errors due to rotating parts in positive displacement (PD) or turbine instruments. In addition, the Micro Devices smart meter self-checking function verifies the overall performance of the instrument (sensor, transmission, and signal processing) without interrupting the production process and without removing the instrument from the pipeline, thus ensuring the reliability of the measurement. degree. The smart meter self-verification function can set the schedule or click the button to complete the instrument performance check in a few minutes.

Micro Motion Coriolis meters lead the process manufacturing industry in terms of quality, measurement performance and reliability, and are part of Emerson's range of smart, digital field devices. These devices make the PlantWeb digital plant structure more powerful. When these flow meters are integrated into the PlantWeb digital plant structure, they can further reduce costs, increase plant availability, and are more in line with safety and environmental requirements.
