The Rosemount 4051SFP Integral Orifice Flow Meter is specifically engineered to provide highly accurate flow measurement in small line sizes ranging from 0.5 to 1.5 in. (15 - 40 mm). By utilizing a primary element integrated in a meter run, this solution ensures optimal repeatability and provides ease of installation for compact piping configurations.
Designed to withstand tough processes and harsh environments, the 4051SFP is built on an all-welded hermetic stainless steel SuperModule platform that effectively resists overpressure and line pressure effects. This robust construction is backed by an industry-leading 20 year limited warranty and 20 year stability, ensuring long-term performance and peace of mind. With a span accuracy of 0.025% and a wide 800:1 rangedown, it delivers unmatched precision while minimizing the need to stock multiple unique models.
Modernize your maintenance routines with integrated Bluetooth® connectivity, which allows you to simplify configuration and maintenance while significantly increasing personnel safety by helping to avoid hazardous locations. The device further enhances operational awareness through built-in advanced diagnostics, such as Process Intelligence, Loop Integrity, and Dedicated Plugged Impulse Line detection. These insights keep you informed of potential issues before they impact your operations.
Every Rosemount 4051SFP comes fully configured, leak-tested, and ready to install right out of the box for fast installation. For critical applications, the meter is SIL 2/3 certified to IEC 61508 by an independent third party, making it a trusted choice for high-integrity safety installations. Users can easily monitor process data via a large, graphical backlit display that supports seven languages and provides faster response times of less than 50ms.
