For stack airflow measurement in coal fired boilers, all facilities subjected to 40 CFR Part 75 must have a flow monitoring system that satisfies continuous monitoring requirements. Air Monitor’s CEMS flow rate monitoring system meets the EPA mandated requirements relative to 40 CFR Part 75. Key advantages of an Air Monitor CEMS system are:
| EPA Requirement | Air Monitor Solution |
|---|---|
| Measurement location | Dual platforms not necessary to pick up velocity profile stratification in the stack |
| Interference check | AUTO-purge III clears debris in particulate-laden airflow |
| Calibration error | AUTO-cal function calculates calibration error |
| Relative accuracy | Air Monitor’s multi-point averaging approach ensures high accuracy matching RATA tests performed by third parties |
| Bias | Pre-RATA test available from Air Monitor |
