Rosemount™ 3418 Eight-Path Gas Ultrasonic Flow Meter
High-accuracy custody transfer 8-path meter with swirl immunity. Requires minimal straight run and no flow conditioner—ideal for compact installations.
Key Features
- Maintain custody transfer accuracy with minimal upstream piping and no flow conditioner using an eight-path design that compensates for swirl, asymmetry, and crossflow, reducing pressure loss, blockage risk, and maintenance requirements.
- Enable compact installations with as little as 5D upstream piping while maintaining OIML R137 Class 0.5 performance.
- Increase operational flexibility with >100:1 rangeability to support wide flow conditions with fewer meter runs.
- Simplify troubleshooting with Smart Meter Verification that converts diagnostic data into clear, actionable insights.
- Improve measurement confidence using multi-path diagnostics that detect changing flow profiles and process disturbances early.
- Minimize downtime with non-wetted transducers that can be serviced or replaced under pressure without special tools.
