Case Study: Enhancing City Gas Station Safety with the BL-CH4 MINI in Poland

Background
With increasing urban development and the widespread use of natural gas, city gas stations play a vital role in ensuring continuous and safe energy supply. However, traditional inspection methods for methane leak detection are often labor-intensive, time-consuming, and expose personnel to potential safety risks.

Challenge
A city gas company was facing difficulties in performing frequent and efficient leak detection across its network of urban gas stations. The stations were often located in densely populated or traffic-heavy areas, making ground-based inspection both disruptive and hazardous.

Solution: BL-CH4 MINI Sensor Integration
To address these challenges, the company adopted the BL-CH4 MINI, a lightweight laser methane detection sensor, mounted on a drone platform. The system uses TDLAS (Tunable Diode Laser Absorption Spectroscopy) to detect methane remotely and accurately in PPM·m (parts per million-meter), enabling real-time aerial scanning of gas pipelines, valves, and storage units within the gas station.

Deployment Process

Flight Planning: Pre-programmed routes were set to fly around key gas infrastructure.

Data Collection: The drone flew at a safe distance, scanning all potential leak points while transmitting methane readings in real time.

Analysis & Reporting: The system flagged high methane concentrations, allowing rapid decision-making and follow-up by ground crews.

Results

Efficiency: Reduced inspection time by 60% compared to manual checks.

Accuracy: Detected micro-leaks that were previously overlooked using traditional sniffers.

Safety: Minimized personnel exposure to hazardous areas.

Non-Disruptive: Allowed inspection without interrupting station operations or traffic.

The BL-CH4 MINI sensor, combined with drone technology, provided a non-contact, precise, and safe method for city gas station inspection. This successful deployment not only enhanced leak detection capabilities but also supported the company’s goal of smarter urban gas management.
