I measured the flow rates of dust monitors 5, 7 and 9 in the LVEA using the Top Trak flow meter model no. 822-13-OV1 PV1-V1 serial no. 46313. The flow rate should read .1 scfm. The measured flow rates were

location 5: .095 scfm
location 7: .028 scfm
location 9: .087 scfm

With the dust monitors turned off, the flow measured -.005 scfm.

I could not adequately adjust the flow rate on location 7 and 9 to .1 scfm. I was able to readjust it back to ~ .1 scfm on location 5. I have removed locations 7 and 9 from the LVEA.
Further measurements need to be done on the remaining dust monitors in the LVEA.
