TOTAL VOLUME CALCULATIONS for Mass Flow Controlled PM10
Systems
TE-6070, TE-6070D, TE-6070BL, TE-6070D-BL
To calculate the total volume of air sampled through the (filter) during your sampling run, take a set-up
reading (when you set the sampler up the SSP was 46.69, which is set up reading) and an ending
reading, look at recorder chart and use the number where red ink pen stops, goes down, for our
example lets assume the ending number was 45. Take 46.69 + 45 = 91.69 91.69/2 = 45.85. So the
continuous recorder reading you would use is 45.85. Put that into formula on bottom of worksheet.
1/m((I)[Sqrt(Tav/Pav)]- b)
m = sampler slope
b = sampler intercept
I = average chart response
Tav = daily, weekly, monthly, or seasonal average temperature
Pav = daily, weekly, monthly, or seasonal average barometric pressure
Sqrt = square root
Example:
m3/min = 1/17.6685((45.85)[Sqrt(291/757)]-(8.9094))
m3/min = .0566 ((45.85)[Sqrt(.3844)] 8.9094)
m3/min = .0566 ((45.85)[ .62 ] - 8.9094)
m3/min = .0566 ((28.427) 8.9094)
m3/min = .0566 (19.5176)
m3/min = 1.105
ft3/min = 1.105 x 35.31 = 39.01
Total ft3 = ft3/min x 60 x hours that sampler ran
Assume our sampler ran 23.8 hours (end ETI reading - start ETI reading)
** Be certain ETI is in hours otherwise convert to hours **
Total ft3 = 39.01 x 60 x 23.8 = 55,706.28 ft3
Total m3 = 1.105 x 60 x 23.8 = 1577.94 m3

Weighing, and Calculation of PM10 Concentration Measurements.
