The Rosemount 3814 stands as the pinnacle of liquid ultrasonic flow meter technology, engineered specifically for high-precision hydrocarbon flow measurement. Designed to meet the stringent requirements of API Chapter 5.8 and OIML R117, this four-path ultrasonic flow meter serves as the gold standard for custody transfer applications, blending operations, and refinery balance.

Precision and Accuracy in Custody Transfer

With an industry-leading measurement uncertainty of < ±0.027%, the Rosemount 3814 ensures total confidence in your fiscal data. Its advanced four-path configuration eliminates swirl-induced distortion, providing reliable data even in turbulent flow regimes. The full-bore design ensures no pressure drop, optimizing efficiency in complex industrial flow control networks.

Advanced Electronics and Real-Time Diagnostics

Powered by the robust Rosemount 3810 Series electronics, this flow meter provides lightning-fast acoustic sampling and real-time flow state recognition. Operators can leverage the MeterLink software to access powerful predictive maintenance insights, including real-time monitoring of flow symmetry and transducer health. This non-wetted transducer design allows for field servicing without disrupting pipeline integrity, significantly reducing operational downtime.
