Patented T-shape sensor DP flow meter with Bluetooth connectivity, 150:1 rangedown, and SIL 2/3 certification.
The Rosemount 3051CFA Annubar Flow Meter represents the industry standard in dependable flow measurement, integrating a patented sensor design with cutting-edge WirelessHART® technology. This high-performance Annubar flow meter features a unique T-shape sensor with a flat upstream surface that provides a fixed separation point, ensuring superior performance over a wide flow range. The design includes a stagnation zone specifically positioned to reduce measurement noise, eliminate inaccuracies, and prevent particulates from clogging the sensor.
Modernize your process monitoring with integrated Bluetooth® wireless connectivity, which simplifies maintenance and service tasks by removing the need for physical connections or specialized configuration tools. Users can interact with the device through a graphical, back-lit display that supports eight different languages and remains easy to read in all lighting conditions. For streamlined commissioning, the device features quick service buttons for instant on-site configuration.
Single Pipe Penetration: This flow meter is capable of measuring both flow and pressure through a single pipe penetration, maintaining a small profile to reduce permanent pressure loss.
Extreme Scalability: Suitable for massive industrial applications, it supports line sizes ranging from 2 to 96 inches (50 to 2440 mm).
Proven Stability: Delivers a 10-year installed stability and a 150:1 rangedown, providing reliable measurements for diverse application requirements.
Leak Reduction: Complete flow assemblies are factory leak-tested and calibrated, reducing potential leak points by up to 70% while simplifying the installation process.
The Rosemount 3051CFA is SIL 2/3 certified to IEC 61508 by independent third parties, making it a trusted choice for safety-instrumented installations. It is equipped with advanced diagnostics, including Loop Integrity and Plugged Impulse Line detection, which identify electrical issues or piping obstructions before they can impact process quality or safety. When utilized in a wireless network, the SmartPower™ module ensures up to 10 years of maintenance-free operation with >99% data reliability.
