Emerson 3051SMV MultiVariable Transmitter Original Intelligent PressureTransmitter
The Rosemount 3051S MultiVariable Transmitter delivers unprecedented performance and capabilities by providing superior flow calculations including fully compensated mass or volume, energy, and totalized flow. Specify the level of compensation that best matches the application:
■ Gas, natural gas, and steam measurement: Utilize full compensation (differential pressure, line pressure, and temperature measurement)
■ Saturated steam: Utilize differential and line pressure, or differential pressure and temperature measurement
■ Liquids: Utilize differential pressure and temperature measurement
■ Liquids at stable temperatures: Utilize differential pressure measurement
■ 4–20 mA HART® , WirelessHART®, FOUNDATION™ Fieldbus protocols

■ Quickly configure, service, and troubleshoot with access to all devices near the technician at speeds up to 10 times faster than traditional HART® connections.
Diagnostics
■ The Loop Integrity diagnostic continuously monitors the electrical loop to detect issues that affect the communication signal and will alert you to corrosion, water in the housing, or an unstable power supply.
■ The Plugged Impulse Line diagnostic continuously monitors for plugged impulse lines and alerts you to abnormal conditions so you can take proactive measures before it affects the quality of the process.
■ Diagnostic events are tracked in the built-in diagnostic log which allows you to see the device status at all times.
■ These capabilities are safety certified for your most critical applications.
Enhanced software
■ Application specific configuration allows you to transform your pressure transmitter into a flow meter with a totalizer or a level transmitter with volume calculations.
■ Process alerts can be configured for any dynamic variable. They can be given a custom name, assigned target thresholds, and can notify via HART alert or analog output alarm.
Quick service buttons
■ Straightforward menus and built-in configuration buttons allow you to quickly commission the device.
■ Configure in hazardous-area locations without removing the transmitter cover using external buttons.
