GAS DETECTION
Portable, ATEX-certifi ed methane quantifi cation technology for the oil and gas sector
Accurately quantifying fugitive methane emissions is critical for oil and gas operators under growing environmental and regulatory pressure. Conventional detection systems often struggle in hazardous environments, where safety certifi cation and reliable performance are crucial.
The new SEMTECH® HI-FLOW 3 from Sensors Inc. is engineered
specifi cally for ATEX Zone 1 applications, bringing industry-leading precision to the fi eld. Building on the success of HI-FLOW 2, this next-generation portable analyser combines spectroscopy- based methane sensors with a high-output sampling fan, delivering fl ow rates of up to 500 LPM. The system achieves minimum leak detection down to 0.025 LPM (≈1 g/hr), while accommodating signifi cantly higher maximum leak rates than comparable instruments.
At its core, a state-of-the-art Tunable Diode Laser Absorption Spectroscopy (TDLAS) sensor ensures methane-specifi c measurements, thereby eliminating interference from other gases present across upstream, midstream and downstream operations. Compact, battery powered and extremely rugged, HI-FLOW 3 offers end users at oil and gas plants and refi neries the accuracy and certifi cation needed to meet today’s methane monitoring challenges.

Precision hydrogen leak detection for water and gas utility networks
INFICON’s Sensistor® XRS9012 is
designed to deliver reliable hydrogen leak detection for utility companies, with water pipelines being one of its key applications. Precise leak detection helps maintain network integrity, reduces losses, and ensures safety in municipal and industrial water systems, where undetected failures can result in considerable operational and environmental consequences.
The instrument uses cost-effective forming gas (5% hydrogen, 95% nitrogen) as a tracer, detecting with sensitivity down to 0.7 ppm Hâ‚‚ in air. Its response time of less than one second and quick recovery enable operators to perform continuous testing confi dently, even in challenging fi eld conditions. The ability to detect very small leaks helps water utilities identify issues early, minimising disruptions and repair costs.
With its rugged IP55-rated aluminium housing, ergonomic design, and extended battery life, the Sensistor®
XRS9012 is ideal for fi eld deployment in challenging environments.
Adjustable sensitivity and diagnostic features improve reliability, while fast recharging supports high productivity.
Beyond water pipelines, the technology is also used in wastewater networks, telecom cable systems, and industrial infrastructure, while hydrogen energy systems could be a long-term application. For today’s operators, however, the XRS9012 provides a proven solution for leak detection in the water and utility sectors where accuracy and durability are vital.
