Rosemount 3051S Series of Instrumentation

Overview

The Rosemount 3051S Series of Instrumentation is a scalable platform for integrated pressure, flow, and level measurements, engineered to achieve unparalleled productivity and efficiency across an entire plant operation. Featuring fast start-ups, reduced operating costs, and increased accuracy, the 3051S Series can optimize operations in four critical areas: production, quality, energy efficiency, and safety and environment.

As an authorized supplier of Emerson instrumentation, Seven Star LLC proudly offers the Rosemount 3051S Series to oil and gas, chemical, power generation, and water treatment facilities across the Sultanate of Oman, Muscat, and the wider GCC. By leveraging the scalable power of the 3051S across an entire operation, plant teams minimize process variability, gain greater process insight, reduce maintenance and downtime, and meet regulatory demands.

Measurement Principle

The Rosemount 3051S Series is built around the all-welded hermetic stainless steel SuperModule platform, which resists overpressure and line pressure effects to ensure 0.025% accuracy in Ultra and Ultra for Flow performance classes. These performance classes deliver 15-year stability and a 15-year limited warranty, with a rangedown ratio of up to 200:1 producing reliable measurements across a wide range of application conditions.

The patented Coplanar platform underlying the 3051S allows two pressure-sensing isolating diaphragms to enable differential pressure measurement, while also supporting gauge and absolute measurement configurations. This scalable architecture integrates seamlessly with manifolds, primary elements, and remote seal solutions, giving engineers a single platform adaptable to pressure, DP flow, and DP level applications.

Engineering Design of the Rosemount 3051S

The Rosemount 3051S Series offers an intuitive interface with a large, graphical, back-lit LCD display, improved accessibility through remote display options, and enhanced process and electrical loop insights through Advanced Diagnostics and PlantWeb alerts. Devices arrive fully assembled and leak-tested from the factory for simple installation and maintenance, with pressure ranges up to 4000 psi (275 bar) and a burst pressure limit of 10,000 psig (689.5 bar).

The platform integrates seamlessly with 4-20mA HART, WirelessHART, and FOUNDATION Fieldbus protocols, giving system integrators flexibility across both wired and wireless plant architectures. MultiVariable options, high-pressure capabilities, and remote seal compatibility extend the 3051S Series across pressure, flow, and level measurement roles that would otherwise require separate dedicated instruments.
