Safety over 13,000 km: gas leak detection with Axetris sensors

The challenge: an ageing network with risks

Parts of Romania’s natural gas network, over 13,000 kilometers in length, date back to the 1960s. The outdated infrastructure and older low-pressure systems raise the risk of methane leaks and therefore also explosions – especially in densely populated areas. Previously used leak detection methods were often based on inaccurate and slow sensors. A more precise solution was sought.

The solution: fast and reliable leak detection with Axetris sensors

The answer came from Smartech, a specialist in flow measurement and fluid analysis. The company has developed a portable laser measuring device (PLD) equipped with the compact LGD gas sensor from Axetris. TDLAS technology (Tunable Diode Laser Absorption Spectroscopy) enables precise detection of even the smallest methane concentrations – in less than two seconds and also in mobile applications.

A special bonus: The sensor measures methane (CH₄) and ethane (C₂H₆) simultaneously. Since only natural gas contains ethane, real gas leaks can be clearly distinguished from biological gases from decaying matter, avoiding false alarms. In addition, a GPS module documents the exact location of each leak.

From suspicion to repair

Trained specialists use the PLD to search defined risk areas. The results are visualized and assessed cartographically in real time. If a leak is suspected, verification is carried out by drilling within a radius of 50 meters. If the suspicion is confirmed, excavators uncover the pipe – with a success rate of over 90%. This allows damaged seals to be replaced quickly and efficiently.

The effect: better safety at lower costs

The combination of Leister sensor technology and Smartech expertise not only saves time and money when searching for leaks, but also actively protects people, the environment and infrastructure. Less unnecessary digging and fewer emissions – a real step forward for safety in the gas network.

Smartech and Axetris – a strong partnership for greater precision, efficiency and sustainability in the gas supply.
