Sixteen inch Coriolis meters!

High capacity Coriolis flowmeters with DN400 (16 inch) process connections provide high accuracy measurement for challenging applications

Emerson Process Management has expanded its range of Micro Motion ELITE® High Capacity Coriolis flowmeters with the introduction of a large line size version with DN400 (16 inch) process connections. This ELITE High Capacity Coriolis meter addresses the need for high accuracy, large line size measuring instruments and provides a high technology option for applications that have historically used mechanical/volumetric devices.

Emerson’s ELITE High Capacity line is the most comprehensive high flow rate Coriolis meter offering in the industry today. With the widest breadth and most flexible offering for any large line size application, ELITE High Capacity Coriolis meters are installed and operating in a wide range of applications throughout the world. The introduction of the DN400 version expands the scope of Micro Motion High Capacity Coriolis flowmeters to many more challenging applications including oil and gas pipelines, refinery oil movement and storage, speciality chemicals and marine bunkering.

Emerson’s highly accurate ELITE Coriolis product offers the flexibility to measure a wide variety of fluids. Ideally suited for difficult applications, the unique design delivers unparalleled measurement sensitivity and stability while delivering consistent, reliable performance over the widest flow range. Options include Super Duplex stainless steel for corrosion resistance and high chloride/high pressure applications, and 316L SS for high temperature and standard applications. The ELITE High Capacity meter is also a critical component of the Micro Motion MID-Certified Bunkering System, the first globally certified, mass-based measurement system for marine bunkering on-board barges and vessels.

The ELITE High Capacity Coriolis product line includes ten sensor models covering DN150-DN400 (6-16 inch) line sizes. They have flow rates up to 3,266,000 kilogrammes/hour and density accuracies of ± 0.0005 grammes per cubic centimetre. The compact design means that the new DN400 version needs just 1300 mm between mounting flanges and, depending on the flow conditions and process fluid properties, ELITE High Capacity Coriolis meters can be mounted in any orientation. They have a wide temperature range of - 240ºC to 200ºC, with the optional high temperature version extending this range to 350ºC. With no moving parts, Micro Motion Coriolis flowmeters are not subject to wear or measurement drift associated with the mechanical components of positive displacement (PD) or turbine meters.

Micro Motion ELITE High Capacity meters also offer two-phase flow capability for batching, loading, and entrained air applications. The meter’s density performance enables even small changes in density to be detected in pipeline distribution applications.

Emerson’s Smart Meter Verification, available on the ELITE Coriolis line, delivers additional 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 enabling fast, easy, in line meter performance assurance.

With over 750,000 installations worldwide, Emerson’s Micro Motion meters are proven across diverse applications that range from process measurement to well production management; to pipeline distribution and storage terminals. High accuracy mass flow measurement means devices are ideally suited for fiscal and custody transfer monitoring, as required by regulatory authorities.
