Rosemount™ 3415 4+1 Dual-Configuration Gas Ultrasonic Flow Meter

Designed to minimize fiscal measurement uncertainty, the Rosemount 3415 4+1 Ultrasonic Flow Meter combines the power and performance of a field-proven Rosemount four-path chordal, British Gas-design meter (certified to OIML R137 1&2 Accuracy Class 0.5) with a one-path, reflective check meter in a single body. The reflective path increases sensitivity to costly buildup on pipeline walls, enabling operators to take necessary action before measurement is adversely impacted. The meter is equipped with ultra-fast 3410 Series Electronics that generate a wealth of predictive diagnostics displayed via MeterLink™ Software, providing a wealth of flow intelligence to help expedite identification of costly process upsets.
