The Rosemount 3051SFP Integral Orifice Flow Meter is a premier multivariable device specifically customized with an integral orifice primary element. This integrated meter run assembly is engineered to facilitate highly accurate flow measurement and repeatability in small line sizes (0.5 - 1.5 in. / 15 - 40 mm) while providing an integrated, trouble-free solution that eliminates unnecessary pipe penetrations.
Equipped with the Ultra for Flow performance class, the 3051SFP achieves an optimized ±0.04% of reading accuracy. The device features built-in flow calculations for the direct reporting of fully compensated mass flow, volumetric flow, and energy flow. To ensure best-in-class calculations, Callendar-Van Dusen sensor matching is utilized to significantly improve temperature accuracy.
Built for harsh environments, the all-welded SuperModule™ design offers industry-leading stability and a 15-year limited warranty. This meter supports multiple communication protocols, including WirelessHART®, which delivers over 99% data reliability and reduces wiring costs. The field-replaceable SmartPower™ module further ensures up to 10 years of maintenance-free operation.
The Rosemount 3051SFP is SIL 2/3 certified to IEC 61508, making it a trusted component for safety-instrumented systems. Its advanced diagnostics suite—including Process Intelligence, Loop Integrity, and Plugged Impulse Line detection—provides comprehensive coverage to identify abnormal process conditions and electrical issues before they impact your operations.
