The SPH Engineering FluX Methane Ethane Core Sensor is a UAV-integrated dual-gas sensor measuring methane (CH4) and ethane (C2H6) simultaneously at 1 Hz. The ethane channel enables thermogenic versus biogenic methane source discrimination — distinguishing fossil fuel pipeline leaks from natural biological methane sources to eliminate false positives in complex survey environments. Integrated with SkyHub and UgCS for georeferenced, real-time dual-gas data acquisition, it is the definitive sensor for oil and gas pipeline inspection where source attribution matters.

Dual Gas CH4 + C2H6. Thermogenic Source Discrimination. 1 Hz.
The FluX Methane Ethane Core Sensor measures both methane (CH4) and ethane (C2H6) simultaneously at 1 Hz — one dual-gas reading per second throughout the survey flight. Ethane is a reliable thermogenic gas marker: it is present in fossil fuel pipeline leaks but absent from biogenic methane sources such as wetlands, agriculture, and landfills. By analyzing the CH4/C2H6 ratio in real time, operators can confidently distinguish genuine pipeline leak events from natural background methane — eliminating false positives and prioritizing infrastructure integrity responses. Integrated with SkyHub for georeferenced acquisition and UgCS for real-time ground station monitoring.

Thermogenic vs. Biogenic. Source Attribution in Flight. Ethane is present in fossil fuel gas leaks and absent from biological methane sources. By measuring both CH4 and C2H6 simultaneously, the FluX dual-gas sensor enables real-time source attribution — confirming whether a detected methane anomaly is a pipeline leak or a natural background source, before the drone lands.

Eliminate False Positives. Prioritize Real Leaks. In complex survey environments with mixed methane sources — agriculture, wetlands, landfills, and pipeline infrastructure — single-gas CH4 sensors cannot distinguish leak events from background. The FluX CH4/C2H6 sensor resolves this ambiguity, ensuring field teams respond to confirmed thermogenic leak events rather than chasing biogenic background signals.

Georeferenced Dual-Gas Maps. Regulatory-Ready from Landing. CH4 and C2H6 concentration data is captured with synchronized GPS position throughout the mission via SkyHub — producing georeferenced dual-gas maps that integrate directly into GIS platforms and reporting workflows for pipeline integrity documentation, environmental compliance, and regulatory submissions.

The SPH Engineering FluX Methane Ethane Core Sensor is a UAV-integrated dual-gas sensor measuring both methane (CH4) and ethane (C2H6) simultaneously at a 1 Hz sampling rate. The addition of ethane detection alongside methane enables thermogenic versus biogenic methane source discrimination — a critical capability for oil and gas pipeline inspection, where distinguishing fossil fuel leaks from natural biological methane sources eliminates false positives and prioritizes genuine infrastructure leak events.

Key Features

  • Dual-Gas CH4 + C2H6 Detection — Simultaneous measurement of methane and ethane concentrations; ethane is a reliable thermogenic gas marker absent from biogenic methane sources, enabling confident source attribution
  • Thermogenic vs. Biogenic Source Discrimination — The CH4/C2H6 ratio distinguishes fossil fuel pipeline leaks (thermogenic, ethane-present) from natural biological methane sources such as wetlands, agriculture, and landfills (biogenic, ethane-absent) — eliminating false positives in complex environments
  • 1 Hz Sampling Rate — One dual-gas measurement per second for continuous, high-temporal-resolution gas concentration data throughout the survey flight
  • In-Situ Contact Sensing — Measures gas concentrations in the ambient air mass directly surrounding the drone — ideal for close-proximity leak confirmation, low-altitude pipeline inspection, and detailed emissions mapping
  • SkyHub Integration — Integrates with the SkyHub onboard computer for automated, georeferenced dual-gas data acquisition synchronized with UAV GPS position and telemetry
  • Real-Time UgCS Monitoring — Live CH4 and C2H6 concentration data streamed to the UgCS companion application on the ground station for immediate anomaly detection and operator awareness during flight
  • Georeferenced Data Output — Dual-gas concentration data logged with synchronized GPS position for direct GIS integration and regulatory reporting
