With 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 % 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% 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 w here 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% 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."
