METHANE DETECTION AND MONITORING


ith the arrival of new methane emissions standards and legal reporting dates, the detection and monitoring of environmentally


damaging gases is the spotlight like never before. For residential, industrial and utility applications, Teledyne Gas & Flame Detection (Teledyne GFD) is offering vital assistance with its new MethaSense range of battery-powered methane detectors, which allows users to take advantage of cutting-edge NDIR (non-dispersive infrared) sensor technology. All three models in the versatile, autonomous new product family - MethaSense, MethaSense XP and MethaSense Trace - feature patented NDIR sensors for reliable and precise methane detection. To suit residential and commercial applications, MethaSense is a compact, wireless natural gas detector with a range of 0-5 per cent volume. High methane selectivity and immunity to sensor poisoning ensure accurate detection without false alarms, making this state-of-the-art detector ideal for preventing gas-related incidents in homes and small businesses. Integrated audible and visual alarms provide immediate alerts to safeguard occupants and property, while its compatibility with advanced metering infrastructure supports smart home integration. Progressive signal processing algorithms ensure MethaSense detects, alarms and monitors methane at concentrations as low as 10 per cent of the lower explosive limit (LEL) for enhanced safety. Optional wireless (LoRaWAN) connectivity enables real-time gas detection visualisation, further boosting safety and efficiency with clear, actionable insights. Offering low cost of ownership, MethaSense delivers both affordable protection and peace of mind. In addition, 10+ years of battery life means MethaSense operates independently for continuous protection, even during power outages.


Also part of the product family is MethaSense XP, which is engineered for industrial environments where robust performance and


reliability are essential. MethaSense XP’s rugged design and reliable detection capabilities ensure worker safety and operational continuity, especially in areas where maintenance access is limited. It combines the same advanced NDIR sensor technology with enhanced durability and wireless communication options, including LoRaWAN, NB-IoT and Bluetooth. MethaSense XP again features audible and visual alarms, while its 10+

year battery autonomy and immunity to corrosion and saturation make the detector ideal for continuous safety monitoring in demanding conditions. With ATEX and IECEx certifications, MethaSense XP operates reliably in hazardous zones. Completing the family is MethaSense Trace,


a high-performance methane detector for LDAR (leak detection and repair) and utility applications, where accurate and autonomous methane monitoring is essential for regulatory compliance and environmental protection. A rugged build with IP67 ingress protection rating for outdoor use ensure uninterrupted performance in harsh conditions, reducing operational risks and maintenance costs. Exceptional methane sensitivity provides 10× higher methane selectivity than previous- generation sensors, with a detection range that extends from 50 ppm to 100 per cent volume for both low-emission environmental monitoring and high-concentration safety thresholds. A fast and comprehensive solution, the detector delivers 24/7 methane emission monitoring, detection and quantification across large-scale industrial sites. By combining real-time sensing, cloud-based analytics and automated reporting, MethaSense Trace enables operators to detect, localise and measure methane emissions with precision. This not only helps reduce emissions but also ensures full compliance with new methane regulations.


As of 5 August 2025, operators in the EU must submit detailed reports on their annual source- level methane emissions in accordance with the EU Methane Regulation (previously Regulation 2024/1787). The reports need to include comprehensive data on methane emissions from all relevant sources within the facility. Independent verification is also necessary.


“NDIR technology, as utilised by all three detectors in our new MethaSense series, offers high selectivity, fast response times and long-term reliability,” explains Régis PREVOST, product line manager, Teledyne GFD. “Users benefit from natural gas detectors that provide a low-maintenance, cost-effective, versatile solution for continuous methane monitoring, supported by key features that include up to 10+ years of battery life, zero recalibration requirements, wireless connectivity options, and suitability for smart infrastructure and safety-critical environments.”

EXPLOSION GAS ANALYZERS FOR ZONE 1 APPLICATIONS


A


METEK Process Instruments has expanded its 993X series of gas analyzers – including both 993X and 9933 models - with new explosion proof (Ex d) enclosures certified for ATEX and IECEx Zone 1 hazardous locations. The new design enables reliable analyzer installation in applications where purge gas is unavailable or impractical, addressing a common challenge in remote and utility-limited facilities. The explosion proof 993X enclosure is rated IP66 and NEMA 4X, allowing outdoor installation and operation in minimally temperature-controlled environments. By eliminating the need for a continuous inert purge gas supply, the design helps reduce installation complexity, operating costs, and overall system infrastructure requirements.


“Many customers rely on purge-protected analyzers, but those systems are not practical in every Zone 1 location,” says Michael Gaura, senior product manager at AMETEK Process Instruments. “The explosion proof 993X gives users a robust alternative that maintains measurement performance.” The 993X series primarily uses ultraviolet (UV) spectroscopy to provide continuous measurement of sulfur compounds and other key components in natural gas and biomethane streams, including hydrogen sulfide, carbonyl sulfide, and methyl mercaptan. The analyzers are also widely used in sulfur recovery and removal processes to measure sulfur-containing species such as sulfur dioxide and carbon disulfide, supporting process control, emissions compliance, and product quality. Other technologies can also be integrated to measure the concentrations of hydrogen and carbon dioxide in these end user applications, when required. With the addition of explosion proof certifications, the 993X series offers greater flexibility for operators designing analyzer shelters and hazardous area installations across oil and gas production, processing, and renewable gas applications.
