Emerson Improves Hygienic Micro Motion® Coriolis Meters with Next-Generation Transmitter Technology

(Product News, 28 Oct 2009)

Emerson Process Management announces the availability of the Model 2400S transmitter with next-generation MVD(TM) technology on its hygienic Micro Motion® H-Series Coriolis meters. The Model 2400S transmitter expands meter installation options for H-Series Coriolis meters to include integral or remote mounting in the field, or control room mounting using a DIN rail, panel or rack format.
Micro Motion Coriolis H-Series meters are ideal for food & beverage and life science industries. The H-Series was specifically designed to find the optimum balance between raw sensitivity to flow and density, and the need for compactness and drainability. The benefits are the ability to clean and drain the flow tubes while delivering high turndown capability with uncompromising flow, density and % concentration (e.g. Brix, % Solids) measurement performance in varying real-world conditions. In addition, thanks to its fundamental design and low drive frequency, the hygienic Micro Motion Coriolis H-Series meters offer great immunity to entrained gas, or two phase flow.
Emerson's Micro Motion Model 2400S is equipped with next-generation MVD digital processing technology that delivers true and complete meter verification. The verification identifies sensor health while the meter is in line, the process is flowing, and without secondary references. This unique feature eliminates disruptions caused by traditional meter tests and ensures the meter is performing to original factory specifications.
With next-generation MVD technology, the Model 2400S provides faster meter response time and advanced algorithms to deliver excellent performance in empty-full-empty (EFE) batching. In EFE batching the piping starts empty, fills with liquid, remains full for the duration of the batch, and then empties upon completion of the batch. This batching is commonly found with railcar, tanker truck loading and multi-product lines. Because the piping and the meter must be emptied between each fill, measurement can be a challenge when using a flowmeter that is configured for only liquid processes. The Model 2400S on the Micro Motion H-Series Coriolis meters handles the application without losing measurement performance or accuracy.
The Micro Motion H-Series meter delivers mass flow accuracy up to ±0.1% and volume flow accuracy up to ±0.15% on liquids, mass flow accuracy of ±0.5% on gases, and liquid density accuracy up to ±0.001 g/cc. With no moving parts to wear out or break down, no intrusive parts, and with no special flow or piping requirements, Micro Motion H-Series meters offer an outstanding, overall hygienic metering solution for the food, beverage, life sciences and pharmaceutical industries
The H-Series is available with DeviceNet or PROFIBUS DP communication protocols in addition to FOUNDATIOn Fieldbus and the traditional interfaces such as 4-20 mA, frequency and HART®. DeviceNet and PROFIBUS DP are widely used in the food, beverage, and life science industries with PLCs. Direct digital communications with the PLCs means that two wires can now carry secondary and tertiary process variables and instrument/process diagnostic information, as well as the primary measurement. The result is that one instrument can provide flow, density and temperature measurements, eliminating the need for multiple sensors and the wiring/configuration costs associated with them. In addition, digital communications unlock instrument diagnostic information, such as drive gain, meter verification and other alarms.
The Model 2400S is available in either standard painted aluminum or 316L stainless steel housing rated to IP66 and IP67. It can be coupled with the Micro Motion H-Series Coriolis meter that is certified by the European Hygienic Equipment Design Group (EHEDG) and 3-A authorized. This measurement solution is perfect for applications requiring excellent cleanability, corrosion resistance, and chemical compatibility in clean-in-place environments.
The Micro Motion Coriolis Hygienic H-Series with scalable transmitter architecture is 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 these flowmeters are integrated into the PlantWeb architecture.
