Using molbloc™/molbox™ to Calibrate the FTS for Environmental Monitoring (235.96 KB)

This document describes the hardware setup and other recommendations for testing the orifice flow meters used for verification/calibration of flows into PM2.5 particulate monitoring instruments. The Chinook Engineering Streamline flow transfer standard (FTS) is used by leaving the inlet to the orifice open to atmosphere and drawing the air flow through the device utilizing a downstream vacuum source (sub-atmospheric pressure).
