Rosemount 3051CFP Integral Orifice Flow Meter
WWW.DISTRIBUTORALATINDUSTRI.COM | Rosemount 3051CFP Integral Orifice Flow Meter | The Rosemount 3051CFP Integral Orifice Flow Meter is an industrial flow measurement instrument manufactured by Rosemount, a brand of Emerson. It uses the differential pressure (DP) measurement principle, with an integrated orifice element built into the measurement pipe assembly
Rosemount 3051CFP Integral Orifice Flow Meter
The Rosemount 3051CFP is specifically designed for flow measurement in small-diameter pipelines ranging from ½ to 1½ inches (15–40 mm). Its integrated, self-centering orifice plate helps reduce measurement errors caused by plate misalignment and variations in the pipe’s internal diameter.
The instrument measures the pressure difference generated as fluid passes through the orifice. The transmitter then processes the differential pressure signal to calculate the flow rate based on the configured measurement parameters, fluid characteristics, and operating conditions.
With its integrated measurement element, the Rosemount 3051CFP helps simplify installation, reduce potential leakage points, and support consistent flow measurement across a variety of industrial applications.
Key Features and Benefits
- Integral Orifice Design: Features an integrated orifice element to simplify installation and reduce assembly complexity.
- Compact Pipe Measurement: Designed for small pipe sizes of ½ inch, 1 inch, and 1½ inches.
- Differential Pressure Technology: Measures flow based on the pressure difference generated across the orifice plate.
- Self-Centering Orifice Plate: Helps minimize measurement errors caused by plate misalignment.
- Factory-Assembled and Leak-Tested: The complete assembly is tested for leakage and calibrated to help simplify installation.
- Wide Transmitter Rangedown: Offers a transmitter rangedown ratio of up to 150:1, depending on the configuration. This does not represent a guaranteed flow turndown ratio.
- Optional Digital Display: An optional backlit graphical display is available for local measurement readings.
- Bluetooth® Connectivity: Available on selected configurations to facilitate instrument configuration and maintenance.
- Advanced Diagnostics: Optional diagnostic capabilities can support loop integrity monitoring and impulse line blockage detection.
- Multiple Communication Options: Communication protocols vary depending on the selected model code and configuration.
Operating Principle
The Rosemount 3051CFP operates using the differential pressure principle through the following process:
- Fluid Flow: The process fluid flows through the pipe section containing the orifice plate.
- Pressure Differential Generation: The orifice plate creates a pressure difference between the upstream and downstream sides.
- Differential Pressure Measurement: The transmitter measures the pressure difference generated across the orifice.
- Flow Rate Calculation: The instrument’s electronics process the differential pressure signal to determine the flow rate based on the configured parameters and fluid properties.
- Signal Transmission: The measurement results are transmitted to a compatible control system or displayed locally when the selected configuration supports a local display.
Advantages Over Conventional Orifice Metering Systems
The Rosemount 3051CFP offers several advantages for industrial flow measurement applications:
- Compact Measurement Assembly: Integrates the orifice element and transmitter into a compact measurement solution.
- Simplified Installation: Helps reduce installation complexity compared with separately assembled orifice measurement components.
- Improved Orifice Alignment: The self-centering orifice plate helps minimize alignment-related measurement errors.
- Reduced Potential Leakage Points: The integrated assembly can reduce the number of potential leak paths compared with conventional arrangements.
- Enhanced Maintenance Support: Optional diagnostic and communication features can help simplify troubleshooting and instrument maintenance.
The Rosemount 3051CFP Integral Orifice Flow Meter is suitable for industrial processes requiring compact, reliable flow measurement in small-diameter pipelines. Before selecting a unit, verify the process fluid, operating pressure and temperature, required flow range, pipe size, material compatibility, and communication requirements.
