    Hello everyone. Just found this site while searching for information on the MS1800 system in our facility. I'm sure I'll learn a great deal from all of you here.

    Thanks for allowing me to be a part of such an awesome organization!

    Air Flow Measurements

    I measured air flow using Vane annemometer & Velgrid in a grill (1200mmx350mm) and got two different readings. I am not sure which one is accrate.
    Vane annemometer =5400 Cubic Meter/Hour (used a factor of 0.573) for double deflection Grill.
    Velgrid Reading = 7200 CMH (This does not use any Factor).

    I am afraid that I may get a different reading if I use Hood to measure the CMH.
