9. Using the above procedure, adjust the ball valve for readings at 50, 40, and
30 inches and record on data sheet. You should have 5 sets of numbers 10
numbers in all.
10. Manually turn sampler off.
To download the calibration worksheet please visit, www.tisch-
env.com/calibration-worksheets and select the TE-1000 PUF calibration
worksheet. The TE-1000 PUF Sampler Calibration Data Sheet has been
attached with data filled in from a typical calibration. This includes the
transfer standard orifice calibration relationship which was taken from the
Orifice Calibration Worksheet that accompanies the calibrator orifice. Since
this calibration is for a PUF sampler, the slope and intercept for this orifice
uses standard flows rather than actual flows.
The five orifice manometer readings taken during the calibration have been
recorded in the column on the data worksheet titled H2O (in). The five
Magnehelic Gage readings taken during the calibration have been recorded under
the column titled FLOW (magn).
The orifice manometer readings need to be converted to the standard air flows
they represent using the following equation:
Qstd = 1/m[Sqrt((H20)(Pa/760)(298/Ta))-b]
Qstd = actual flow rate as indicated by the calibrator orifice, m3/min
H20 = orifice manometer reading during calibration, in. H20
Ta = ambient temperature during calibration, K ( K = 273 + Co)
298 = standard temperature, a constant that never changes, K
Pa = ambient barometric pressure during calibration, mm Hg
760 = standard barometric pressure, a constant that never changes, mm Hg
m = Qstandard slope of orifice calibration relationship
b = Qstandard intercept of orifice calibration relationship.
Once these standard flow rates have been determined for each of the five run points,
they are recorded in the column titled Qstd, and are represented in cubic meters per
