Introduction In recent years, as urbanization and industrialization accelerate, natural gas has taken on an increasingly important role in energy structures. However, the widespread adoption of natural gas also lies multiple challenges including hidden safety risks, low management efficiency, and growing pressure to save energy and reduce carbon emissions. On one hand, safety incidents such as gas leaks and carbon monoxide poisoning continue to occur, posing threats to life and property. On the other, traditional gas metering methods are struggling to meet the accuracy, operational efficiency,...

Safety is the first and most fundamental requirement for natural gas application. A single leak, if undetected, can lead to catastrophic consequences of explosions, poisoning, oreven large-scale industrial accidents. For households, incomplete combustion remains a leading cause of carbon monoxide poisoning worldwide, while in industrial environments, the presence of toxic gases such as hydrogen sulfide or ammonia poses additional hazards. To address these risks, Cubic offers a comprehensive portfolio of sensing technologies, ranging from methane detection to electrochemical CO and toxic gas sensors,...

In residential settings, the role of gas monitoring is primarily centered on protecting families from accidental leaks. Homes are typically equipped with natural gas pipelines, LPG cylinders, or other fuel sources for daily energy needs. Despite the convenience, these systems are prone to failures-aging pipelines can corrode, connections can loosen, and appliances such as stoves, heaters, and boilers can malfunction. In poorly ventilated spaces, even minor leaks may quickly reach dangerous concentrations.

■ NDIR Four-channel Technology to Acetic acid and Ethanol Cubic OEM CO detector and CH4 detector, built on advanced sensor platforms, combine fast response and stable performance, making them ideal for integration into smart alarms or home safety networks. Cubic residential safety monitoring solutions are designed with accessibility and ease of use in mind. Compact detectors installed in kitchens, basements, or near gas appliances can provide continuous surveillance. When concentrations exceed safe thresholds, the device issues alarms both audible and visible, to alert occupants to evacuate or...

Industrial environments present a more complex landscape for gas monitoring, both in terms of scale and diversity of hazards. In high-risk industrial environments such as oil and gas extraction, coal mining, LNG transportation, and urban underground gas networks, methane leaks pose serious threats to personnel safety and equipment integrity. To address the challenge, Cubic has developed methane safety monitoring solution based on TDLAS and NDIR technologies for different industrial application scenarios.

Cubic TDLAS-based methane sensing solution, is designed for fixed-point online monitoring. Leveraging tunable diode laser absorption spectroscopy, Cubic TDLAS methane sensor provides high selectivity, accuracy, and resistance to interference, maintaining stable measurements even in complex background gases and high-humidity conditions. Deployed at critical nodes such as pipelines, regulator and metering stations, valve pits, storage facilities, and LNG terminals, these sensors enable real-time concentration monitoring, rapid leak detection, and trend analysis Complementing fixed leakages monitoring,...

Accurate gas measurement is essential for natural gas trade, as it underpins settlement and compliance with national regulations. To ensure reliability, Cubic pioneers ultrasonic technology in gas metering across residential, commercial, and industrial applications.

Residential Ultrasonic Gas Flow Sensor Module Leveraging mature ultrasonic technology, Cubic developed residential ultrasonic gas meter module series USM-MN/MP-G1.6/G2.5/G4 and USM-MN/MP-L-G1.6/G2.5/G4 modules, and commercial residential ultrasonic gas meter module series USM-G10/G16/G25/G40. Cubic residential ultrasonic gas meter module series, USM-MN/MP-G1.6/G2.5/G4 and USM-MN/MP-L-G1.6/G2.5/G4 modules, adopt a specially designed flow channel that enhances measurement accuracy and anti-contamination performance. They support measurement of air, various natural gases, natural gas blended with...
