Continuous methane monitoring for digesters, flares and the fence line.
Cairn Sensing places solar and battery-powered sensors around anaerobic digesters, gas handling equipment and the plant boundary, so you know when methane is escaping and when it isn’t.
Free 90-day pilot. No cost, no long-term commitment.
Leaks and odor complaints rarely arrive with a timestamp
A plant with anaerobic digesters handles biogas every hour of the day. Relief valves lift, cover seals age, flares go out, and gas lines develop small leaks. Most of that is found on a walk-around, if it’s found at all.
When a neighbor calls about odor, the question is what happened, and when. Without continuous readings, the honest answer is often “we don’t know.”
How Cairn fits
- Fence-line sensingSensors along the plant boundary show what’s actually leaving the site, around the clock.
- Near-equipment sensingUnits near digesters, gas storage and flares catch fugitive leaks and flare outages early.
- A timeline for complaintsWhen someone calls, you can check the readings and the wind for that hour.
- Solar and batteryNo wiring into plant power or controls. Units report over cellular, with satellite fallback.
- Alerts at your thresholdSet the level that matters to your operators and get notified when it’s crossed.
How a pilot works
We start with a 15-minute call about your site, what you monitor today and where readings come from.
If it’s a fit, we install a small number of sensors and run them for 90 days at no cost. You get the alerts and the data, and at the end you decide whether it’s worth keeping.
Cairn is a monitoring tool. It sits alongside your existing process controls and safety systems and doesn’t replace them.
