During most industrial inspections, the air is not the first thing teams think about. Inpection crews are focused on access, data quality, and staying on schedule. But around assets such as tanks, stacks, flare systems, and live piping, what you cannot see in the air can matter more than what you can see on the structure.
This is why Voliro is adding real-time flammable gas detection to the Voliro T—and why it is now included in every Voliro T subscription.
Industrial inspections frequently take place near live process equipment where flammable vapors may be present. When a drone is operating at height, close to a stack, or downwind of a small leak, handheld and fixed sensors may not detect changes in the atmosphere until it is too late. As a result, inspection teams are often forced to make decisions based on assumptions rather than real-time data from the point of inspection.
This creates a critical gap:
Without flammable gas data at the drone’s location, teams are effectively blind to a key safety variable along the flight path.
Monitor flammable gas conditions in real time with live %LEL readings directly from the aerial platform. This provides immediate awareness of the atmosphere where the drone is flying—not just at ground level or fixed sensor locations.
Built for inspections on live assets where shutdowns are costly or impractical. Real-time gas monitoring supports safer decision-making during inspections and can help simplify hot-work permitting in classified hazardous areas.
Operators receive on-screen alerts when %LEL readings exceed configurable thresholds, ensuring rapid awareness of changing atmospheric conditions and enabling timely adjustments to flight paths or stand-off distances.
The flammable gas payload operates alongside existing Voliro T NDT payloads, enabling combined inspection and safety monitoring without additional setup or workflow complexity. Available as a complimentary upgrade with all Voliro T subscriptions.
By adopting the Voliro T, operators already eliminate one of the biggest inspection risks: working at height. The aerial robotic platform allows inspectors to collect high-quality NDT data remotely, without scaffolding, rope access, or manned lifts.
However, one risk remains—the potential presence of flammable gas at the inspection point.
Even with strong site procedures and plant-wide detection systems, the atmosphere where the drone is operating has traditionally been a blind spot. This is the gap Voliro’s flammable gas payload is designed to close.
If you are flying near live piping, tank nozzles, vents, or stacks, you do not just want accurate inspection data. You also want to know whether the air surrounding the aerial platform is approaching a flammable range before it becomes a hazard.
At Voliro, safety is not treated as an optional add-on.
We do not want teams to fight for extra budget or make job-by-job decisions about whether a safety layer can be justified. Flammable gas awareness should not depend on commercial trade-offs.
That is why the flammable gas payload is now included in every Voliro T subscription.
By making it standard, Voliro ensures that all users have access to safety-critical information when operating near assets where flammable gas may be present.
The Voliro T flammable gas payload is built around NevadaNano’s Molecular Property Spectrometer (MPS) Flammable Gas Sensor.
During flight, the sensor continuously samples the surrounding air and reports flammable gas concentration as a percentage of the Lower Explosive Limit (%LEL). This data reflects the actual atmosphere at the drone—not at ground level or a nearby fixed sensor.
Key features include:
Rather than relying on a single target gas and correction factor, the MPS sensor analyzes the thermodynamic properties of the air-gas mixture to estimate how close it is to becoming ignitable.
