The Rosemount 3051S is a "no-equal" solution for complex industrial flow sensor requirements. Built on the all-welded hermetic SST SuperModule platform, it provides unmatched 15-year stability. This multivariable DP flow solution allows primary elements to be pre-assembled, creating a ready-to-install differential pressure flow measurement system that reduces potential leak points by 70%.
To ensure maximum uptime, the 3051S features plugged impulse line diagnostics and process intelligence to detect abnormal conditions before they cause failure. Utilizing WirelessHART flow measurement protocols, this transmitter offers over 99% data reliability in secure networks, while the SIL 2/3 certified transmitter rating ensures compliance with the strictest safety standards.

Performance Class: Choose Ultra for Flow for high-precision custody transfer or Ultra for standard control.
Material Compatibility: For corrosive fluids, select Tantalum or Alloy C-276 wetted materials instead of standard 316L SST.
Protocol Selection: Use WirelessHART for remote locations to save on wiring costs, or HART/Fieldbus for integrated wired systems.
Pre-assembled Efficiency: Order with pre-assembled primary elements to ensure the device is factory leak-tested and calibrated.
Remote Display: If the transmitter is in a hard-to-reach area, utilize the remote display option for easier loop connection and monitoring.
Alignment: Ensure proper orientation of impulse lines to prevent gas trapping in liquid lines or liquid trapping in gas lines.
Diagnostic Alerts: Monitor Loop Integrity diagnostics to identify electrical issues before they impact the process.
Impulse Line Checks: Regularly review the Plugged Impulse Line status through the transmitter interface to prevent measurement drift.
Power Management: For wireless models, the SmartPower module provides up to 10 years of life; schedule replacements based on the selectable update rate.
