Product Description

Product Description

Emerson Rosemount 3051CF Stainless Steel Orifice Flowmeter

The Emerson Rosemount 3051CF Stainless Steel Orifice Flowmeter is a high-precision, integrated solution designed to deliver accurate and reliable differential pressure (DP) flow measurement for liquids, gases, and steam in demanding industrial environments. Part of Emerson's 3051 family, the 3051CF combines a stainless steel orifice plate assembly with a multivariable pressure transmitter to provide a compact, field-proven system for custody transfer, process control, and energy management applications. Its robust construction, advanced sensor technology, and digital communication capabilities make it ideal for industries such as oil and gas, chemical processing, power generation, and water/wastewater treatment.

Core Technology and Operating Principle
The 3051CF operates on the differential pressure principle, where an orifice plate installed in a pipeline creates a controlled pressure drop proportional to the flow rate. The device measures this pressure difference using a capacitive sensor, which detects changes in capacitance caused by the deflection of a silicon-based sensing element. By applying Bernoulli's equation and ISO 5167 standards, the transmitter calculates the volumetric or mass flow rate with exceptional accuracy.

A key innovation is the integration of multivariable measurement, allowing the 3051CF to simultaneously capture differential pressure (DP), static pressure, and process temperature. This eliminates the need for separate instruments and enables real-time compensation for fluid density variations in gas and steam applications. The transmitter's digital signal processing (DSP) enhances measurement stability by filtering noise from turbulence, vibration, or mechanical stress, ensuring consistent performance in dynamic conditions.

The flowmeter's stainless steel orifice plate and wetted components provide superior corrosion resistance and mechanical durability, even in aggressive environments like offshore platforms, chemical reactors, or high-temperature steam systems. Its design complies with ASME B40.7 and ISO 5167-2 standards for orifice plate geometry and installation.

Technical Performance and Features
The 3051CF delivers exceptional accuracy and versatility:

The transmitter's modular design allows easy replacement of components like the sensor module or electronics without removing the orifice plate from the pipeline, minimizing downtime. Its self-calibrating circuitry reduces the need for frequent manual calibration, while built-in diagnostics continuously monitor sensor health and signal integrity.

Advanced Diagnostic and Asset Management Features
The 3051CF incorporates predictive diagnostics to enhance operational reliability and reduce unplanned downtime. Key diagnostic capabilities include:

Sensor Health Monitoring: Detects sensor degradation, overpressure events, or coating buildup, providing early warnings of potential failures.
Orifice Plate Integrity Checks: Identifies wear, erosion, or blockage in the orifice plate, ensuring measurement consistency.
Signal Integrity Alerts: Notifies operators of electrical noise, grounding faults, or wiring issues affecting accuracy.
Self-Validation: Periodic checks verify measurement integrity without manual intervention, critical for pharmaceutical or food-grade applications.
These diagnostics are accessible via HART, Fieldbus, or Emerson's AMS Device Manager, enabling proactive maintenance planning and compliance with functional safety standards like IEC 61508 (SIL 2/3).

Ease of Use and Integration
Installation and configuration are streamlined through intuitive interfaces:

Local Display: A backlit LCD with push-button controls allows on-site setup and troubleshooting without pipeline shutdown.
Remote Configuration: HART or digital protocols enable adjustments via handheld communicators, mobile apps (e.g., Emerson Mobile Remote View), or control system interfaces.
Digital Twin Compatibility: Integrates with Emerson's PlantWeb® ecosystem for real-time analytics, predictive maintenance, and performance optimization.
The 3051CF's universal design supports multiple process connections (e.g., flanged, threaded, or welded) and adapts to legacy 4–20 mA systems while supporting modern digital upgrades.
