Ensuring Safety, Compliance, and Operational Integrity with Dynament Infrared Gas Sensors 

Why Methane Leak Detection Matters 

Methane (CH₄) is the primary component of natural gas, a highly combustible gas. Even small leaks in pipelines, storage, or processing systems can pose significant hazards: 

• Explosion & Fire Risk: Methane-air mixtures in the right concentration range are flammable and explosive. 

• Regulatory & Safety Compliance: Operators must detect and mitigate leaks to comply with safety and environmental standards. 

• Operational Integrity: Undetected leaks degrade system efficiency, waste gas, and increase costs. 

• Environmental Impact: Methane is a potent greenhouse gas; leaks contribute to emissions losses. 

To manage these risks, reliable, fast, and certified methane detection is essential in natural gas infrastructure and operations. 

Industry Challenges: Risks of Inadequate Leak Monitoring 

Detecting methane leaks in natural gas systems is challenging due to: 

• Wide Concentration Ranges: Leaks may range from trace ppm to percent volume / LEL levels. 

• Harsh Environments: Sensors must operate in variable temperatures, humidity, contaminants, and pressure. 

• Explosive Atmospheres: Equipment must meet ATEX, IECEx, or other explosion-proof certifications for Zones 1/2. 

• Fast Response & Low Drift: Leaks must be detected quickly, over a long service life, and with minimal recalibration. 

• Integration into Safety Systems: Alarm outputs, data interfaces, and diagnostics are needed for control systems. 

Operators risk delayed leak detection, non-compliance, safety incidents, and economic loss without robust methane sensing. 

Dynament offers a comprehensive lineup of non-dispersive infrared (NDIR) sensors tailored for methane and hydrocarbon leak detection, optimized for safety, reliability, and regulatory use.
