Smokestacks don't lie. Neither does your EPA report.
Cement kilns, steel furnaces, chemical reactors — every combustion event emits a measurable signature. Flux CEMS units bolt directly to stack flanges, survive 1,400°F flue gas, and stream CO₂, SO₂, NOₓ, and particulate data to your compliance dashboard in under 8 milliseconds. No interpolation. No estimation. The number the inspector sees is the number the sensor measured.
- IP67-rated enclosures rated for −40°C to +85°C
- NDIR + electrochemical dual-sensor redundancy
- Automatic QA/QC flags per 40 CFR Part 75
Real methane readings. No smoothing. No delays.
Aging landfill infrastructure leaks methane at rates that compound quarterly. Our soil-embedded sensor grids triangulate plume origin within 3 meters, quantify flux rates in g/m²/day, and generate the geospatial boundary maps that LMOP compliance requires. The data below is live from a 47-acre municipal landfill in Alameda County, California — published unedited.
- Plume origin triangulation to ±3 meter accuracy
- LMOP and EPA Method 25C compatible output
- Automatic OGI-equivalent leak detection alerts
Soil breathes. Flux listens at 900 MHz.
Enteric fermentation, manure management, and nitrogen cycle emissions account for 11% of US greenhouse gas output — yet most agricultural facilities still rely on IPCC Tier 1 emission factors calculated from herd counts and feed logs. Flux replaces estimation with measurement: solar-powered sensor stakes every 200 meters, continuous N₂O and CH₄ readings, and automatic Scope 1 inventory updates that sync to your CDP disclosure platform before each reporting window.
- Solar-powered, 18-month autonomous operation
- LoRaWAN mesh network, no cellular dependency
- Direct CDP and GHG Protocol inventory integration
The cost of a missed reading: $70,117 per day.
EPA's Clean Air Act Section 114 penalties for CEMS data gaps start at $25,000 per day per violation. Add Title V permit deviation fees, state enforcement multipliers, and the cost of a third-party audit triggered by a data gap, and a single missed quarterly filing can exceed $280,000 before legal fees. Flux's redundant sensor architecture and automated substitute data procedures eliminate data gaps before they become violations.
- Automated substitute data under 40 CFR 75.33
- Real-time compliance status dashboard per stack
- Regulatory counsel review queue built into workflow
