Industrial Emission Quality Monitoring with iNut: SO2 · NOx · CO · Dust Monitoring & Automatic Reporting

Traditional emission monitoring has too many blind spots: manual, periodic measurements mean only a handful of scattered data points each month, figures are scattered across paper logs and Excel files, and when a parameter exceeds the threshold at midnight, no one finds out until it's too late. On top of that, every reporting period means gathering numbers by hand, calculating averages, and cross-checking QCVN limits — time-consuming and error-prone.

Modern emission monitoring isn't about "measuring for the sake of it" — it's about letting data stream in continuously, with the system watching thresholds and generating reports on its own. iNut brings exactly that toolkit to the mouth of the smokestack: dedicated sensors, wireless transmission, edge-layer processing, remote alerts and an SCADA dashboard — all on a platform you fully control.

Every trustworthy report starts with an accurate measurement. iNut pairs dedicated sensors for each parameter — SO2, NOx, CO and dust (PM/TSP), plus O2, flue gas temperature and flow rate for conversion to standard conditions — then brings it all together in one place in real time. No more one device per parameter and one screen per device.

Smokestacks are often located where running cables is difficult and grid power isn't available. iNut RS485 / WiFi Mesh transmits data wirelessly and runs on solar power, so it can be installed right at the base of the stack without long cable runs. At the edge layer, iNut PC aggregates data from multiple points, runs conversion logic and provides 4G uplink when needed — paired with iNut Datalogger for buffered storage and iNut OPC (OPC UA/Modbus/XML-DA) to interface with SCADA systems or regulatory monitoring stations.

Measuring is one thing — responding in time matters even more. Set the threshold once: when dust or CO reaches the alert level, iNut automatically closes a relay to turn on exhaust fans, opens treatment system valves (dust filtration, absorption, solution spraying) or reduces furnace load — then stops automatically once parameters return to a safe range. This closed control loop helps curb the risk of exceeding limits right at the source.

Whenever a threshold is exceeded, someone always knows. When a parameter reaches a QCVN limit or a measuring device malfunctions, iNut PC immediately pushes an alert via Email/Telegram with the value, measurement point location and timestamp. The operations team can respond within minutes instead of discovering it during the reporting cycle — even outside business hours.

All data converges on the iNut Platform — a self-hosted cloud with a SCADA dashboard: real-time charts for every parameter, hourly/daily trends, a map of measurement points and device status. Managers can view everything remotely via the iNut app, while the system automatically compiles and generates reports for each period — hourly, daily and monthly averages already converted — replacing manual number-gathering.

At the base of a smokestack, alongside a treatment area, or out at an ambient environmental monitoring station, iNut devices keep running thanks to solar power and wireless transmission — no need to run power lines, no need for on-site staff. Install once, and data keeps streaming in continuously; the outdoor-rated enclosure withstands sun, rain, dust and vibration in an industrial setting.
