Product Introduction
The Rosemount 2051CFC from Emerson is a compact differential pressure flow meter designed for reliable measurement in industrial pipelines. It combines an orifice-based primary element with a pressure transmitter in an integrated assembly, simplifying installation and supporting consistent flow monitoring.
Key Features
- Flexible Orifice Design: Available with a compact orifice plate or a patented four-hole conditioning plate.
- Reduced Straight-Run Requirements: The four-hole conditioning plate requires only 2D upstream and downstream in applicable configurations.
- Factory-Assembled Options: Leak-tested and calibrated assemblies help simplify installation and reduce potential leak points.
- Multiple Communication Options: Supports HART®, WirelessHART®, FOUNDATION™ Fieldbus, and PROFIBUS® PA on applicable configurations.
- Easy Commissioning: Selected models offer a local operator interface with built-in configuration buttons.
- Safety Certification: SIL 2/3 certification to IEC 61508 is available for applicable configurations.
Applications
- Oil and Gas: Flow monitoring in production, processing, and pipeline systems.
- Chemical Processing: Measuring compatible process fluids in transfer lines and production processes.
- Power Generation: Monitoring steam, water, and other suitable utility flows.
- Industrial Utilities: Measuring compressed air, fuel gas, and other plant utility flows.
- Process Control and Monitoring: Providing flow signals for control loops, consumption monitoring, and applicable custody transfer systems.
Technical Highlights and Selection Considerations
The 2051CFC combines compact installation with flexible orifice technology. The four-hole conditioning plate is particularly useful where upstream and downstream straight pipe lengths are limited. Applicable configurations support line sizes from 0.5 to 12 inches (15–300 mm).
When selecting a model, confirm the pipe size, process medium, operating pressure and temperature, flow range, orifice type, communication protocol, and required certifications. The necessary straight-run length and measurement performance depend on the selected configuration and installation conditions.
Frequently Asked Questions
Q1: What does the Rosemount 2051CFC measure?
It measures the flow of gases, liquids, and steam using differential pressure generated by an orifice-based primary element.
Q2: What is the difference between a standard orifice plate and a four-hole conditioning plate?
A standard orifice plate provides conventional differential pressure measurement. The four-hole conditioning plate helps manage disturbed flow profiles and can reduce straight-run requirements.
Q3: How much straight pipe is required for the 2051CFC?
The four-hole conditioning plate can require only 2D of straight pipe upstream and downstream in applicable installations. Requirements for other configurations may differ.
Q4: Does the Rosemount 2051CFC support wireless communication?
Yes. WirelessHART® is available on applicable configurations. Wired communication options depend on the selected transmitter.
Q5: What information is needed to select the correct model?
Provide the pipe diameter, fluid type, operating conditions, flow range, preferred orifice configuration, communication requirements, and any applicable safety or certification requirements.
