Rosemount™ 3814 Four-Path Liquid Ultrasonic Flow Meter

High-accuracy 4-path meter for refined products to heavy crude. Full-bore design minimizes pressure drop and maximizes reliability.

From refined products to heavy crude, the highly accurate Rosemount 3814 Four-Path Ultrasonic Flow Meter offers exceptional rangeability and linearity to minimize measurement uncertainty of liquid hydrocarbons. Preferred worldwide for highly accurate, repeatable measurement in accordance with API Chapter 5.8 and OIML R117, the meter features a full bore design that virtually eliminates pressure drop to improve measurement integrity and reliability. Powerful Rosemount 3810 Series Electronics detect changing flow dynamics and help operators pinpoint issues, including blockages upstream of the meter and abnormal flow profiles, to minimize measurement uncertainty.

Key Features

  • Minimize measurement uncertainty and downtime with advanced diagnostics that pinpoint process upsets
  • Identify upstream blockages and abnormal flow profiles in real time using advanced MeterLink Software
    Extend calibration cycles by monitoring meter health to minimize operating and maintenance costs
  • Improve accountability and auditing with high-capacity archive data logs that include pressure and temperature
  • Reduce maintenance costs and eliminate periodic calibration (unless locally mandated) by having no moving parts
  • Further facilitate maintenance with field-replaceable, non-wetted transducers
  • Simplify future upgrades with expandable Rosemount 3810 Series Electronics platform
  • Increase I/O with new Type 4 CPU Module with up to six frequency or digital outputs
