Rosemount™ 3417 4+4 Dual-Configuration Gas Ultrasonic Flow Meter
Fully redundant 4+4 path meter for unmatched accuracy and uptime. Delivers two independent measurements in one meter body.
Key Features
- Achieve continuous measurement validation with two fully independent four-path custody transfer meters operating in a single flow body.
- Reduce custody transfer risk by identifying measurement deviation through real-time comparison of independent meter outputs.
- Simplify installation with a dual-meter configuration that eliminates the need for a second meter run and additional piping.
- Increase operational flexibility with >100:1 rangeability to support wide flow conditions with fewer meter runs.
- Maintain uptime with transducers that can be serviced under pressure without interrupting flow or requiring special tools.
- Accelerate troubleshooting with Smart Meter Verification that converts complex diagnostics into clear, actionable insights.
Frequently Asked Questions
The Rosemount™ 3417 4+4 Dual‑Configuration Gas Ultrasonic Flow Meter provides redundancy by integrating two independent four-path custody transfer meters within a single body, each with its own electronics and transducers, enabling dual measurement for pay/check or parallel validation applications in high-value gas transactions.
The Rosemount™ 3417 Dual-Meter is recommended for natural gas custody transfer applications that require independent measurement verification, such as pay/check installations or stations serving multiple customers. Its dual-meter design enables operators to compare flow rate, speed of sound, and diagnostic data between two independent measurements to detect bias, quantify error, and support contractual verification requirements.
The Rosemount™ 3417 reduces financial risk by providing two independent measurements that can detect divergence caused by process disturbances or installation effects, allowing operators to identify discrepancies early and avoid disputes, billing corrections, and revenue loss in high-volume natural gas pipelines.
The Rosemount™ 3417 should be selected when full redundancy of custody transfer (CT) measurement is required, such as in large transmission pipelines or international custody transfer stations, where regulatory, contractual, or financial requirements demand redundant, independent CT measurement rather than diagnostic-only verification.
In the Rosemount™ 3417, mirrored four-path configurations can produce opposite bias responses when exposed to disturbed flow conditions, while one meter reads low the other would read high, enabling operators to quickly identify and quantify measurement shift caused by swirl, blockage, or installation effects.
