Hydrogen Measurement in Natural Gas Pipelines
Blending of hydrogen at levels up to 30% while maintaining measurement accuracy with Rosemount Ultrasonic
Opportunities to safely and effectively achieve lower emissions
The use of hydrogen in natural gas is seen as a cleaner source of energy and thereby increasing in popularity and demand. Hydrogen blended into natural gas pipelines allows for lower emissions than gas alone while still providing power and heat. This practice is being rapidly adopted in Europe, with some pipelines targeting 100% hydrogen. In North America, customers are still adapting and testing a maximum of 30% in the natural gas stream. The Rosemount™ SeniorSonic 3414 Four-Path Gas Ultrasonic Flow Meter ensures that customers can blend hydrogen into their current pipeline at levels of up to 30% and maintain the accuracy and reliability for which Rosemount is known.

Product Solutions
Preferred worldwide for fiscal measurement, the next-generation Rosemount SeniorSonic™ 3414 Four-Path Ultrasonic Flow Meter retains the field-proven, British Gas-chordal design while significantly increasing sampling speed with ultra-fast Rosemount 3410 Series Electronics. This powerful, high-performance meter minimizes measurement uncertainty by enabling rapid detection of changing flow dynamics such as blockages upstream of the meter, abnormal flow profiles and liquid hydrocarbons. MeterLink™ Software displays a wealth of predictive diagnostics generated by the meter, providing expert flow analysis, flow disturbance alerts and suggested corrective actions, to expedite detection before measurement is impacted.
- Speed issue resolution with 3D view of the flow profile that indicates swirl, crossflow, asymmetry and turbulence
- Reduce manual errors with automatic calculations of AGA 8 Compressibility and AGA 10 Speed of Sound
- Reduce measurement uncertainty with process alerts for wall buildup, liquids, blockage and deviating gas quality
