The Rosemount 2015CFC compact Annubar flowmeter is designed to provide industry-standard performance and reliable flow measurement. The flowmeter's constant velocity pitot tube features a patented T-shaped design with a flat upstream surface, allowing for excellent performance across a wide range of flow rates. During installation, the flowmeter is positioned between the convex flanges, eliminating the need for pressure taps and additional process openings.

Here are the key features of the Rosemount 2051CFC Flanged Annubar Flow Meter:

All-in-One Design: Integrates the 2051C pressure transmitter and Annubar sensor into a compact, flanged assembly—simplifies installation and reduces leak points.

Annubar Technology: Utilizes a patented averaging pitot tube to provide accurate differential pressure measurements across various flow profiles.

Wide Turndown Ratio: Achieves up to 100:1 rangedown with 5:1 flow turndown, enabling precise measurement across a wide flow range.

Direct Mount Configuration: No impulse piping needed, which reduces installation cost and potential measurement drift.

Advanced Communications: Supports HART®, WirelessHART®, FOUNDATION™ Fieldbus, PROFIBUS®, and Low Power protocols for integration flexibility.

Diagnostics and Interface: Comes with basic device diagnostics and a local operator interface for straightforward configuration and maintenance.

SIL Rated: Certified for SIL 2/3 applications per IEC 61508, making it suitable for safety-instrumented systems.

Rugged Construction: Built with 316 stainless steel wetted materials, designed to withstand challenging process environments.

Versatile Applications: Suitable for gas, liquid, and steam service in industries like power, oil & gas, and chemical processing.
