FPD580 Stack Gas Flow Metering System Manual

This document describes the FPD580 series of stack gas flow metering systems, which use a Torbar multi-port self-averaging pitot flow meter for continuous, in-stack measurement of volume/mass flowrate and velocity. It covers manual and automatic versions, MCERTS approval, optional purging for solids contamination, and integration with CEMS analyzers for complete emissions monitoring packages.
