The Rosemount 3051CFP is a specialized integral orifice flow meter engineered specifically for high-accuracy requirements in line sizes from 0.5 to 1.5 inches (15–40 mm). By utilizing a self-centering orifice plate within a dedicated meter run, this differential pressure flow meter eliminates the centering errors common in small-bore piping, ensuring superior repeatability and precision.
This Bluetooth industrial sensor allows technicians to perform maintenance and configuration wirelessly, bypassing the need for physical tool connections. Integrated with WirelessHART flow transmitter technology, the 3051CFP delivers over 99% data reliability. Furthermore, its SIL 2/3 certified architecture provides advanced plugged impulse line diagnostics, proactively detecting piping obstructions before they compromise process safety or quality.

Setting up the Rosemount 3051CFP is designed to be a streamlined process, minimizing potential errors in small line size applications. Follow these expert steps for a successful deployment:
Step 1: Selection & Alignment – Choose the correct self-centering orifice plate for your specific line size, ranging from 0.5 to 1.5 inches (15–40 mm). The self-centering design is engineered to facilitate highly accurate flow measurement by eliminating manual centering errors.
Step 2: Meter Run Integration – Integrate the orifice assembly into the meter run. Every Rosemount complete flow assembly is factory leak-tested and calibrated, which reduces potential leak points by up to 70% compared to traditional field-built installations.
Step 3: Wireless Configuration – Activate the Bluetooth® connectivity to perform maintenance and service tasks without needing a physical connection or separate configuration tools.
Step 4: Rapid Commissioning – Use the Quick Service Buttons and the graphical, back-lit display (supporting 8 languages) to finish commissioning quickly, even in low-light environments.
Step 5: Advanced Diagnostics Check – Verify the Plugged Impulse Line and Loop Integrity diagnostics through the transmitter interface to ensure the system is free of obstructions before full-scale operation.
