Rosemount™ 3418 Eight-Path Gas Ultrasonic Flow Meter

High-accuracy 8-path meter with swirl immunity. Requires minimal straight run and no flow conditioner—ideal for compact installs.

The Rosemount 3418 8-path ultrasonic flow meter crafted, developed, and designed by Emerson, offers the highest accuracy and best in class performance coupled with the same high functionality required by sophisticated fiscal measurement users. The 3418 combines the power of two interlocked 4-path British Gas design meters in one flow meter body. The second set of chords is the mirror image of the first, which allows the meter to cancel out the effects of swirl and cross flow. The 3418 Flow Meter boasts a 0.5 OIML accuracy class and requires only five diameters of straight run and no flow conditioner.

Key Features

  • No flow conditioner reduces compression and pumping costs and eliminates maintenance due to blockages
  • High rangeability of >100:1 ensures fewer meter runs smaller line sizes and lower capital costs
  • 3410 Series Electronics provide fast sampling, an expandable electronics platform and an archive data log containing pressure, temperature and gas composition information which allows the meter to act as a redundant flow computer
  • 3410 Series Electronics calculate corrected volume rates, mass rates and energy rates
  • T-200 Transducers are safely extractable under pressure without special tools (for line sizes up to 36")
  • Significantly reduce time previously spent on data analysis and troubleshooting with the new Smart Meter Verification Basic feature now included in the latest 3410 Electronics firmware update
