Stack emissions monitoring is the continuous or periodic measurement of gases, flow, and related operating conditions released through an industrial stack. For compliance programs, it helps facilities document emissions performance, verify flow data, and support regulatory reporting. OSI supports stack applications with optical flow sensors, integrated data acquisition systems, field commissioning, and technical support.
