Methane gas leak detection is a critical safety, environmental, and compliance requirement across Australia’s high-risk industrial sectors. As a highly flammable hydrocarbon gas, methane presents serious explosion hazards, operational disruption risks, and regulatory exposure when leaks go undetected.
ProDetec delivers engineered methane gas leak detection systems designed for continuous monitoring in demanding industrial environments. From upstream gas production and transmission through to processing, storage, and wastewater infrastructure, our methane leak detection systems are selected, designed, and supported to perform where reliability matters most.
With deep experience in gas detection across Australia and New Zealand, ProDetec supplies certified methane detection technologies backed by local engineering expertise, commissioning support, and ongoing service – ensuring long-term performance, compliance, and confidence.
Methane gas detection involves continuous or periodic monitoring of methane concentrations in the air to detect leaks before they escalate into safety incidents, explosions, or environmental breaches.
Methane is colourless, odourless, and lighter than air. While odorants are added for domestic applications, industrial methane leaks often occur in environments where smell is unreliable or masked by other process gases. This makes engineered methane gas detection essential.
A methane leak detection system typically consists of fixed or portable sensors, control panels, alarms, and integration with safety or shutdown systems. These systems measure methane concentration as a percentage of the Lower Explosive Limit (LEL), providing early warning well before conditions become hazardous.
While methane is lighter than air, other hydrocarbons, such as LPG, require different sensor placement and technologies, which is why methane systems are often specified separately from an LPG gas detector.
The most common methane detection methods include:
Measures methane by detecting how it absorbs infrared light at specific wavelengths. Ideal for long-term stability and harsh environments.
Detect methane through combustion on a heated sensor element, suitable for general LEL detection.
A properly designed methane leak detection system uses sensor technology matched to the application, environmental conditions, and safety objectives. ProDetec engineers assess airflow patterns, gas behaviour, ignition sources, and site layout to ensure methane sensors are positioned for effective early detection.
These systems often integrate with gas detection monitors, alarms, ventilation systems, and emergency shutdown (ESD) logic to minimise risk and response time.
Correct methane sensor placement is critical to the effectiveness of any methane gas leak detection system.
Because methane is lighter than air, sensors are typically installed:
Sensor placement must consider airflow, ventilation systems, temperature gradients, and structural obstructions. ProDetec provides site-specific design support to ensure methane sensors detect leaks quickly and reliably, rather than after gas has dispersed.
For larger or open areas, solutions such as infrared hydrocarbon gas detector technologies may be used to effectively monitor wide zones or perimeters.
Methane gas leak detection systems in Australia must comply with a range of safety, electrical, and hazardous-area standards, depending on the application.
Key considerations include:
ProDetec supplies methane gas detectors and systems that meet relevant Australian and international standards, including IECEx and ATEX certification where required. Our solutions support compliance obligations while also aligning with industry best practices for safety and reliability.
Ongoing performance is equally important. Regular gas monitor calibration ensures methane sensors remain accurate and compliant over their service life, particularly in regulated environments.
Across all sectors, ProDetec delivers methane leak detection solutions tailored to Australian operational realities, compliance obligations, and environmental commitments.
ProDetec does more than supply equipment. We act as a technical partner throughout the lifecycle of your methane leak detection system.

A methane detector may detect methane present in sewer gas, but sewer gas often contains additional compounds such as hydrogen sulphide. Dedicated sensors may be required depending on the application, such as an H2S gas detector.
Modern methane sensors are highly accurate when correctly selected, installed, and maintained. Infrared-based methane sensors offer excellent long-term stability with minimal drift.
Calibration frequency depends on the sensor technology, site conditions, and regulatory requirements. Regular gas monitor calibration is essential to ensure reliable methane leak detection and compliance.
Response time varies by sensor type and environment. ProDetec supplies methane gas monitors designed for rapid response to minimise escalation risk.
