Product Data Sheet PS-00838, Rev C April 2013 Micro Motion® MVD™ Direct Connect™ Coriolis Meters with MVD™ Technology The Micro Motion® MVDTM Direct ConnectTM solution combines the accuracy, reliability, and performance of Micro Motion Coriolis meters with the simplicity of a direct Modbus® interface. The MVD Direct Connect I.S. barrier option enables installation of the meter into hazardous areas and provides the same power conditioning benefits that a transmitter offers. Peak performance Coriolis meter High performance compact drainable Coriolis meter Hygienic compact drainable Coriolis meter Straight tube full-bore Coriolis meter Unique MVD Direct Connect architecture simplifies installation and reduces cost and complexity through direct integration into a Modbus host Complete solution provides access to all Micro Motion process variables, embedded diagnostics, and full sensor configuration Optional compact DIN rail barrier allows hazardous-area installation and provides power conditioning R-Series General purpose flow-only Coriolis meter

Micro Motion MVD Direct Connect Meters Micro Motion Coriolis meters from Emerson Process Management meet a vast range of application needs, ranging from extreme low-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 parts to ensure the best material compatibility. Coriolis meters. Coriolis meters offer dramatic benefits over traditional volumetric measurement technologies. Coriolis meters: • Deliver accurate and repeatable process data over a...

MVD Direct Connect architecture MVD Direct Connect I.S. barrier (Recommended) Hazardous area Barriers installed in safe areas minimize wiring and ground loop issues. Safe area MVD Direct Connect I.S. barrier MVD Direct Connect architecture eliminates transmitters, interface cards, wiring, and cabinet space. Use 4-wire cable between the core processor and the barrier, and use standard RS-485 cable between the barrier and the host. The MVD Direct Connect barrier snaps onto a 35 mm DIN rail, and measures less than 5 × 5 × 1 inches (105 × 110 × 25 mm). Easy on installation Streamlined...

Micro Motion meters and the MVD Direct Connect solution Micro Motion leads the industry with the widest selection of meter types and sizes available. Match the meter to your requirements: sanitary, improved surface finish, hazardous area, high temperature, secondary containment, explosion-proof, and more. MVD Direct solutions can be installed with any Micro Motion meter that accepts an integral core processor. For meters that cannot accept an integral core processor, the MVD Direct Connect solution can be installed with a remote core processor, as long as hazardous area approvals are not...
