Product Data SheetPS-00838, Rev. FFebruary 2022Micro MotionTM MVDTM Direct ConnectTMCoriolis Meters with MVDTM TechnologyThe Micro Motion MVD Direct Connect solution combines the accuracy, reliability, andperformance of Micro Motion Coriolis meters withthe simplicity of a direct Modbus interface. TheMVD Direct Connect I.S. barrier option enablesinstallation of the meter into hazardous areas andprovides the same power conditioning benefits thata transmitter offers. Unique MVD Direct Connect architecturesimplifies installation and reduces cost andcomplexity through direct integration into aModbus host Complete solution provides access to allMicro Motion process variables, embeddeddiagnostics, and full sensor configuration Optional compact DIN rail barrier allowshazardous-area installation and provides powerconditioning

MVD Direct Connect Coriolis Meters with MVD TechnologyFebruary 2022Micro Motion MVD Direct Connect Coriolis Meterswith MVD TechnologyMicro Motion Coriolis meters from Emerson meet a vast range of application needs, ranging from extremelow-flow up to high-flow, high-capacity lines. Cryogenic, hygienic, high-temperature, and high-pressure —Micro Motion meters can handle them all. Micro Motion meters are available with a variety of wetted partsto ensure the best material compatibilityMVD technology makes your Micro Motion meter work smarter Front end signal processing gives faster responsetime and dramatically reduces signal noise Provides reduced wiring costs through use ofstandard 4-wire instrument cable On-board signal processing results in thecleanest, most accurate signal delivered, evenwith tough measurement conditions such asentrained gasMicro Motion MVD Direct ConnectCoriolis metersThe unique architecture of Micro Motion MVDtechnology lowers the power requirements anddistributes safe DC power to the sensor,dramatically lowering installed costs compared totraditional analog meters. The MVD Direct ConnectI.S. barrier conditions the power and providesintrinsically safe DC power and Modbuscommunications to the sensor in the field.In a typical Micro Motion MVD meter, the coreprocessor performs the Coriolis signal processingfunctions. The transmitter then transduces thedigital data to traditional analog or frequencyoutputs for use by the control system. Without thetransmitter, you still have all the sensor and flowrate data, plus management controls such asevents, two-phase flow limits, and totalizers —accessible via Modbus communications.2Micro Motion MVD Direct Connect meters are theideal solution for systems integrators and OEMslooking for the most efficient and cost-effective wayto provide MVD technology to their customers for avariety of fluids including toothpaste, vegetableoils, vinegar, ketchup, mayonnaise, and additives, inapplications like: Material blending skids Juice blending CNG dispensers Remote flow monitoringAccess information when you need itwith asset tagsNewly shipped devices include a unique QR code asset tag thatenables you to access serialized information directly from thedevice. With this capability, you can: Access device drawings, diagrams, technicaldocumentation, and troubleshootinginformation in your MyEmerson account Improve mean time to repair and maintainefficiency Ensure confidence that you have located thecorrect device Eliminate the time-comsuming process oflocating and transcribing nameplates to viewasset informationwww.emerson.com

MVD Direct Connect Coriolis Meters with MVD TechnologyFebruary 2022Micro Motion meters and the MVD Direct ConnectsolutionMicro Motion leads the industry with the widest selection ofmeter types and sizes available. Match the meter to yourrequirements: sanitary, improved surface finish, hazardousarea, high temperature, secondary containment, explosionproof, and more.MVD Direct solutions can be installed with any Micro Motionmeter that accepts an integral core processor.For meters that cannot accept an integral core processor, theMVD Direct Connect solution can be installed with a remotecore processor, as long as hazardous area approvals are notrequired.Micro Motion is continually expanding its meter line. Forinformation on a specific meter, consult the meter product datasheet or contact Micro Motion.Modbus communications and MVD Direct ConnectProLink III softwareCustom softwareFor configuration, management, and viewing process variables,Micro Motion offers ProLink III, a Windows-based softwareprogram.Your custom software can perform the same functions and thentranslate process data into process control. Using industrystandard Modbus protocol, you can read flow rates and totals,start and stop batches, and respond to process fluctuations anderror conditions.ProLink III automatically recognizes the meter it is connected to,retrieves process data, reports status and alarms, and providesdata logging and meter fingerprinting capabilities.ProLink III provides full support for MVD Direct Connectinstallations with or without the barrier.4Micro Motion has published its Modbus interface, providingcomplete access to meter functionality.www.emerson.com
