The Rosemount 3417 is the industry benchmark for fiscal measurement verification. By integrating two independent British Gas-design ultrasonic systems into a single meter body, this dual-configuration flow meter delivers 4+4 path redundancy. Certified to OIML R137 Accuracy Class 0.5, it generates two autonomous measurements on a single meter run, ensuring superior measurement accuracy, uptime, and regulatory compliance.
Equipped with the ultra-fast 3410 Series Electronics, the Rosemount 3417 utilizes MeterLink™ Software to provide real-time detection of flow disturbances. The robust T-200 transducers ensure optimal performance in sour and corrosive environments. With the integrated Smart Meter Verification feature, users can significantly reduce the time spent on data analysis while maintaining a 3D view of the flow profile to monitor swirl and turbulence.

When selecting a Rosemount 3417, the focus is on achieving the highest level of fiscal measurement security. This 4+4 configuration is ideal for high-value gas pipelines where downtime is not an option. Ensure you select the appropriate transducer series (T-21, T-22, or T-200) based on your gas quality; for sour gas or high-pressure applications, the titanium-encapsulated T-200 transducers are the standard for long-term resilience. For those also managing liquid lines, consider the [Rosemount 3810 Series Electronics] to standardize your ultrasonic platform across the enterprise.
The Rosemount 3417's "two meters in one body" design simplifies installation by removing the need for a second meter run or intermediate flanges. During installation, it is critical to ensure the British Gas (BG) orientation is maintained for optimal path coverage. Unlike traditional setups, the patented synchronization method allows for high sampling rates without cross-interference between the two measurement systems. For remote locations where cabling is an issue, we recommend exploring the [Rosemount 3051S Wireless] system for auxiliary pressure and temperature data integration.
Maintenance cycles for the 3417 can be extended by utilizing the Smart Meter Verification Basic feature. This allows technicians to track meter performance against an as-built baseline without a full shutdown. If a transducer requires attention, the T-200 transducers are safely extractable under pressure up to 42", eliminating the need to blow down the pipe. For complex piping layouts where straight runs are limited, the [Rosemount 9295 Process Flow Meter] might be used in secondary lines, but for the main fiscal run, the 3417’s 3D flow profile diagnostics provide the best defense against swirl and asymmetry.
Q: What is the main advantage of the Rosemount 3417's 4+4 dual-configuration?
A: The Rosemount 3417 combines two independent 4-path ultrasonic measurement systems in a single meter body. This provides full redundancy and two autonomous measurements on one meter run, which is essential for fiscal measurement verification and validation.
Q: Can the transducers be replaced while the gas pipeline is under pressure?
A: Yes, the T-200 transducers are robust, titanium-encapsulated, and specifically designed to be safely extractable under pressure without special tools for line sizes up to 42 inches.
Q: Does the meter provide diagnostics for flow disturbances?
A: Yes, integrated MeterLink™ Software provides real-time detection of disturbances like swirl, crossflow, and turbulence using 3D flow profile visualization and predictive diagnostics.
