1 Introduction
1.1 General overview of Rosemount Liquid
Ultrasonic Flow Meter
Rosemount 3814 Liquid Ultrasonic Meters have various configurations that meet
a broad range of customer requirements. Each meter comes fully assembled from
Emerson, and all parts and assemblies are tested prior to shipment.

Troubleshooting Manual
Computer simulations of various velocity profiles demonstrate that four
measurement paths provide an optimum solution for measuring asymmetric
flow. The Rosemount 3814 Liquid Ultrasonic Meter utilizes four cross-bore,
parallel-plane measurement paths to offer a high degree of accuracy,
repeatability, and superior low-flow capabilities without the compromises
associated with conventional technologies. These features make the Rosemount
3814 Liquid Ultrasonic Meter the best choice for custody transfer applications.
The Rosemount 3814 Liquid Ultrasonic Meter technology can be applied to
custody transfer flow measurement applications as shown in the following
section.
1.2 Typical applications
• Custody transfer measurement
• Allocation measurement
• High viscosity, low Reynolds Number applications (where Re ≤5000)
• Check metering
• Leak detection
• Line balancing
• Batch control
• Loading and off loading
• Offshore
— FPSO (Floating Production, Storage and Offshore Loading)
— Offshore Platforms
— Barges
• Pipelines
