MetScan V1: Advanced UAV-Mounted Methane Detection System

As global energy operators strengthen their commitment to safety, emissions reduction, and operational efficiency, fast and accurate methane leak detection has become a critical priority. MetScan V1 by Soarability is a cutting-edge solution designed specifically for this mission—combining advanced laser sensing, intelligent data analytics, and UAV mobility to deliver industry-leading methane inspection capabilities.

Fully compatible with the DJI Matrice 400 and DJI Matrice 350 platforms, MetScan V1 transforms drone platforms into high-precision remote gas sensing tools. Whether deployed over pipelines, well sites, industrial facilities, landfills, or high-rise buildings, it enables operators to detect fugitive emissions from a safe distance and make informed decisions faster than ever before.

Purpose-Built Methane Detection From the Air

MetScan V1 is a UAV-mounted methane 3D scanning system engineered for rapid and efficient leak detection in the natural gas industry. It leverages Open-Path Tunable Diode Laser Absorption Spectroscopy (OP-TDLAS) to remotely detect CH₄ emissions over large or inaccessible areas—without requiring field personnel to approach hazardous zones.

Soarability MetScan V1 is optimized for a wide range of applications, including:

  • Aboveground and underground natural gas pipelines
  • Gas wells and well station components
  • Urban high-rise buildings and indoor leaks (through windows)
  • Utility tunnels, industrial plants, and storage facilities
  • Landfills, wastewater treatment plants, and chemical sites

Remote-Sensing Methane Sensor: High Sensitivity, Long Range

MetScan V1 OP-TDLAS methane sensor delivers industrial-grade accuracy and reliability.

Sensor Specifications

  • Method: Open-Path Tunable Diode Laser Absorption Spectroscopy
  • Laser Class: Class 3R (avoid direct eye exposure)
  • Measurement Range: 100 – 99,999 ppm·m
  • Measurement Error: ≤10% (1,000 – 50,000 ppm·m at 20 m)
  • Sampling Frequency: Up to 50 Hz
  • Weight (with gimbal): 890 g

Detection Performance

The Maximum Detection Distance (MDD) and Lowest Detection Limit (LDL) depend on several field factors, including:

  • Gas cloud size and concentration
  • Reflective surface properties and incidence angle
  • Sunlight interference
  • Sensor movement speed

Typical results under real conditions:

  • 1,000 ppm·m gas cloud detected continuously at 75 m under sunny conditions
  • 2,500 ppm·m gas cloud detected continuously at 100 m under cloudy conditions

This range performance allows operators to inspect assets safely from a distance, even when gas concentrations are low or environmental conditions are challenging.

Precision Imaging and Stabilization

Three-Axis Stabilized Gimbal

Soarability’s specially engineered 3-axis gimbal ensures:

  • Ultra-stable laser targeting
  • Vibration-free measurements
  • Clear, high-resolution imaging—even at long distances

This stability is essential for accurate methane detection in windy, dynamic, or high-altitude environments.

Integrated Laser Rangefinder

The onboard laser rangefinder provides:

  • Up to 800 m ranging distance (low-light)
  • Up to 500 m ranging distance (daylight)

Together with gimbal altitude and positional data, the system calculates:

  • Accurate methane reading coordinates (latitude & longitude)
  • Relative altitude of leak sources
  • Precise georeferencing for inspection reports

Dual-Camera Imaging System

MetScan V1 includes two integrated cameras:

  • 35 mm (equiv.) wide-angle camera for area coverage
  • 300 mm (equiv.) telephoto camera for detailed component imaging

Both views are fused in real time, enabling operators to simultaneously observe the broader environment and zoom in on specific valves, joints, or risers.

Intelligent Data Platform: Soarability Spatiotemporal Insights (SSI)

MetScan V1 works seamlessly with SSI, a browser-based platform for real-time monitoring and advanced post-flight analysis.

Advanced 2D/3D Visualization

SSI offers multiple methane visualization layers:

  • 3D point clouds
  • 2D grid heatmaps
  • Ray (line) projections
  • Interpolated methane maps

These tools provide spatial clarity, helping analysts understand plume dispersion, concentration intensity, and leak severity.

Realtime Data Streaming with MQTT

All methane, positional, and imaging data can be streamed directly to:

  • Control centers
  • Cloud dashboards
  • SCADA systems
  • Emergency monitoring platforms

This ensures that decision-makers receive critical leak information instantly.

Web Embedding for Operational Integration

The SSI interface can be embedded into clients’ existing control software or enterprise dashboards, enabling operators to integrate methane data with:

  • Inspection logs
  • Facility maps
  • Operational analytics
  • Maintenance workflows

Closed-Loop Analysis and Multi-Data Sync

SSI dramatically enhances operational efficiency:

  • One-click navigation to leak points
  • Time-series synchronization of concentration, imagery, and spatial coordinates
  • Instant tagging of anomalies with environmental context
  • Rapid reporting for maintenance teams

Application Scenarios

Natural Gas Well Stations

MetScan V1 captures high-resolution imagery and methane concentration data around:

  • Valves
  • Flanges
  • Wellhead components
  • Processing units

With centimeter-level positioning, operators can identify specific equipment responsible for emissions while keeping UAVs safely outside restricted zones.

Aboveground and Underground Pipelines

The system uses automated belt-type scanning and 50 Hz sampling to generate dense methane point clouds along pipeline routes. SSI instantly converts these into:

  • Pipeline heatmaps
  • Leak location markers
  • Dispersion analysis maps

This supports efficient corridor inspections, anomaly verification, and regulatory-compliant reporting.

High-Rise Buildings

MetScan V1 offers unique capabilities for urban safety:

  • Detects methane through windows and multi-layer glass
  • Identifies indoor and outdoor leak sources
  • Automatically determines a target’s relative altitude
  • Helps inspectors pinpoint which floor or apartment may be at risk

This makes it ideal for dense residential areas where gas incidents pose significant safety risks.

Conclusion

Soarability MetScan V1 is more than a methane detector—it is a complete, intelligent aerial inspection ecosystem. By combining long-range OP-TDLAS detection, precision imaging, 3D analytics, and real-time data streaming, it delivers unmatched efficiency and safety for operators in the natural gas, utilities, and industrial sectors.

Whether used for routine monitoring, emergency response, emissions reporting, or high-risk facility inspections, MetScan V1 empowers organizations to:

  • Reduce operational hazards

  • Accelerate leak detection

  • Improve environmental compliance

  • Strengthen infrastructure resilience

This UAV-based methane scanning solution sets a new standard for aerial gas inspection—bringing accuracy, intelligence, and scalability to the forefront of industrial safety.
