Interphex 2004: Emerson keeps shrinking Coriolis transmitters' size, costs
New York, NY—Emerson Process Management reports that integrating Coriolis flowmeters into its PlantWeb digital plant architecture, programmable logic controller (PLC) systems, or distributed control systems (DCSs) is now easier and less expensive because Emerson just released its ultra-compact Micro Motion Model 1500 MVD Coriolis transmitter.
New York, NY— Emerson Process Management reports that integrating Coriolis flowmeters into its PlantWeb digital plant architecture, programmable logic controller (PLC) systems, or distributed control systems (DCSs) is now easier and less expensive because Emerson just released its ultra-compact Micro Motion Model 1500 MVD Coriolis transmitter. Now on exhibit at Interphex 2004, Model 1500 MVD features multivariable, digital signal processing.
Designed to fit easily into control room panels, Micro Motion Model 1500 MVD transmitter has a simple, four-wire connection to the sensor for power and signal, eliminating the expense of running custom cables or providing a separate power source at the sensor. Model 1500’s small size saves added expense in the control room because it needs only 0.03 cubic feet of space, rather than the 1.0 cubic feet typically required for Coriolis transmitters.
Despite its small size, Model 1500 offers immediate improvements in process measurements due to the transmitter’s advanced, patented, digital signal processing (DSP) technology, called MVD. Model 1500 provides milliamp and frequency outputs for direct mass and volumetric flow measurement, and allows easy monitoring of density, temperature, flow totals and meter diagnostics.
For applications requiring transmission of multiple process variables, Emerson also offers the recently released Micro Motion Model 2500 DIN rail transmitter, which has additional I/O channels that are configurable for the application. Micro Motion flowmeters using the Model 1500 or 2500 transmitters can be placed in all areas of a plant, including hazardous areas. Benefits of using the Micro Motion Model 1500 and 2500 transmitters include:
Lower installed costs by using standard 4-wire cabling, eliminating the need to separately power the sensor, and reducing space requirements.
Improved process performance through reduced raw material usage, reduced batch variability.
Improved production yield/less waste, faster material throughput and faster response time.
Reduced downtime with higher stability, enhanced diagnostics capabilities, and loops that are easier to tune.
Easier to use by providing an easy-to-mount and easy-to-wire package, while still maintaining the superior performance and flexibility of the MVD architecture.
In addition, installation convenience of Model 1500 expands the use of accurate, precise Micro Motion Coriolis technology to power improved manufacturing quality by Emerson’s PlantWeb digital plant architecture. Also, the online monitoring and diagnostics data delivered by Model 1500 provides predictive process and flowmeter health information that PlantWeb delivers to plant operastors, enabling more efficient scheduled and proactive maintenance.
