Coriolis flow measurement for corrosive & harsh environment

High capacity Coriolis meters are ideal for corrosive oil and gas applications

The Micro Motion® ELITE® High Capacity Coriolis meter is now available in Super Duplex material to handle corrosive applications and harsh environments. The Super Duplex meter is available for line sizes from DN 200-250mm (8”-10”) and improved pressure rating to 160 bar (2320 psi).

Super Duplex stainless steel offers the same reliability, accuracy and turn down performance as meters made with 316 stainless steel material, with the added benefit of increased corrosion resistance and pressure rating. Super Duplex delivers excellent resistance to high chloride levels found in the oil field, such as formation water, and is particularly well suited for measuring production fluids and medium pipeline pressure applications. Because of the corrosive compounds in crude oil, natural gas and other hydrocarbon streams, more reliable and robust meters are required that can deliver highly accurate measurement over wide flow ranges. 

The Micro Motion ELITE High Capacity Coriolis meter offers ± 0.10 per cent mass and volume flow accuracy for liquids, and mass accuracy of ± 0.35 per cent for gas. The High Capacity Coriolis meter also offers density accuracies of ± 0.0005 g/cc and can handle a maximum liquid flow capacity of 2,550,000 kg/h. 

Emerson’s Micro Motion Coriolis meters are designed with no moving parts so they are not subject to wear or measurement drift associated with the rotating components of positive displacement (PD) or turbine meters. In addition, Micro Motion Smart Meter Verification delivers measurement confidence by verifying the complete meter performance (sensor, drive and signal processing) while the operation is flowing and without removing the meter from the line. Smart Meter Verification can check meter performance on a set schedule or at the touch of a button in minutes.

Micro Motion Coriolis meters lead the process manufacturing industry in quality, measurement performance and reliability, and are part of Emerson's broad range of intelligent, digital field devices that power the PlantWeb™ digital plant architecture. Further cost savings, increased plant availability, and enhanced safety and environmental compliance are achieved when the flowmeters are integrated into the PlantWeb digital plant architecture.
