On a critical loop, drift between calibrations is a hidden cost: every tenth of a percent the transmitter wanders is either lost product, extra margin, or another trip to the field. The Rosemount 3051S Series is designed to keep that drift small for a long time, with 15-year stability and a 15-year limited warranty in the Ultra and Ultra for Flow performance classes.

At the core is the SuperModule, an all-welded hermetic stainless steel sensor platform. Ultra performance provides up to ±0.025% of span accuracy and 200:1 rangedown, and Ultra for Flow provides up to ±0.04% of reading for DP flow. The same series scales from a single Coplanar or in-line transmitter to integrated 3051SF flow meters, the 3051SMV MultiVariable transmitter for mass and energy flow, the ERS system for tall vessels, and 3051SAL level transmitters with direct mount seals.

Options include advanced diagnostics, a remote display up to 100 ft. (30 m) from the process, SIL 3 capable safety certification, and HART, FOUNDATION Fieldbus, or WirelessHART output. For general purpose and high performance points, see the Rosemount 3051 and the Rosemount 2051.
