Abstract
This paper investigates the feasibility of utilizing a closed four-branch resonant as a concentration sensor during the transportation of natural gas mixed with H2. Accurate detection of changes in H2 concentration is critical to ensuring pipeline operational safety, as an increase in H2 content can lead to delayed fractures or localized cracks within the pipeline. By carefully tuning the parameters of the four-branch closed resonator sensor, this study significantly improves its performance metrics. Specifically, the figure of merit reaches 4.93 × 105, the quality factor is 8.96 × 105, and the concentration detection limit is as low as 1.01 × 10–7. In addition, the device’s simple design and superior performance make it particularly suitable for applications in biosensing, air quality monitoring, and the detection of oxygen and harmful gases.
