Rosemount 3051S Series of Instrumentation
Description
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.
With fast quotation turnaround and technical support, 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, while a common spare-parts pool across pressure, flow, and level duty points lowers overall inventory carrying cost.
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, from low-flow startup transients to full-rate steady-state operation.
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), covering everything from low-pressure utility loops to high-pressure wellhead service.
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.
Key Features
The Rosemount 3051S Series combines scalable architecture with industry-leading accuracy and reliability. Core capabilities include:
- SuperModule platform delivering 0.025% accuracy and resistance to overpressure and line pressure effects.
- Ultra and Ultra for Flow performance classes with 15-year stability and 15-year limited warranty.
- Rangedown ratio up to 200:1 for wide application flexibility.
- Integrates with 4-20mA HART, WirelessHART, and FOUNDATION Fieldbus protocols.
- Large graphical, back-lit LCD display with remote display options.
- Advanced Diagnostics and PlantWeb alerts for enhanced process insight.
- Pressure ranges up to 4000 psi (275 bar), burst limit of 10,000 psig (689.5 bar).
- Seamless integration with manifolds, primary elements, and remote seal solutions.
Industrial Applications
The Rosemount 3051S Series is well suited to oil and gas processing, chemical manufacturing, power generation, and water treatment facilities across Oman requiring scalable, high-accuracy pressure, flow, and level measurement. Its ability to serve pressure, DP flow, and DP level roles from a single platform simplifies spare parts management and technician training across large industrial sites.
With engineering support in Muscat, Seven Star LLC supports refineries, chemical plants, and utilities throughout the Sohar and Salalah economic zones and the broader GCC region with the Rosemount 3051S Series’ scalable measurement platform.

Why Choose Seven Star LLC for the Rosemount 3051S Platform
Because the 3051S SuperModule platform can be configured for pressure, DP flow, or DP level duty from a single hardware base, the biggest sourcing risk is ordering the wrong performance class or output protocol combination for a plant that has already standardized on HART, WirelessHART, or FOUNDATION Fieldbus elsewhere. Seven Star LLC’s engineers confirm the required performance class (Ultra vs Ultra for Flow), rangedown, and communication protocol against the customer’s existing DCS or asset-management environment before quoting, so the delivered unit integrates without a rework cycle. We also help plant teams plan spares around the platform’s modular design – a single SuperModule sensor inventory can support pressure, flow, and level roles – which lowers total spare-parts holding cost, and we arrange calibrated-unit delivery with documentation into Oman and the wider GCC so commissioning schedules aren’t held up by customs paperwork.

About brand
Rosemount is Emerson's brand for pressure, temperature, level and flow measurement, best known for the 3051 pressure transmitter. Frank Werner, Robert Keppel and Vernon Heath founded it in Minnesota in 1956 as Rosemount Engineering Company, first making temperature sensors for aerospace. It moved into the process industries, took the name Rosemount Inc. in 1966, and has been part of Emerson since 1976.
Seven Star LLC is an independent supplier in Muscat. We list Rosemount transmitters, level instruments, flowmeters and analytical sensors, and supply them and their spares to oil and gas, power, water and process plants in Oman and the GCC by model code.

Many Rosemount transmitters share one platform, so the model code tells you what you have. On a 3051, the letter after the number sets the type: C for coplanar (differential or gauge), T for in-line, L for liquid level and CF for a complete flowmeter. The next characters set the measurement type, the range code, the output (4-20 mA HART, FOUNDATION Fieldbus or WirelessHART) and the wetted materials. A transmitter with the wrong range code may work, but with poor accuracy at the point that matters.
Where Rosemount instruments are used
In Oman and the GCC, Rosemount instruments are used across upstream oil and gas, gas plants and LNG, refineries, tank farms and terminals, power and desalination stations, and water networks. Ultrasonic gas meters and tank gauges are used for fiscal and custody transfer measurement.
Ordering Rosemount instruments: what we need
Send the full model code from the nameplate (for example 3051CD2A22A1AM5B4) and the tag if it is a replacement. For a new instrument, send the measuring range, process connection, wetted materials, output protocol and hazardous area approval.
