Total Volume
TE-5000-BL TSP Sampler with TE-5009 Continuous Flow Recorder
To figure out the total volume of air that flowed through the sampler during your sampling
run take a set-up reading (when you set the sampler up manually turn it on and take a
continuous flow recorder reading; in our example it should be 38) and a pick-up reading
(after the sample has been taken again manually turn sampler on and take a continuous
recorder reading; for our example let's say it read 34). Take 38 + 34 = 72 72/2 = 36 so the
continuous recorder reading you would use is 36. Put that into the formula (on bottom of
worksheet):
1/m((I)[Sqrt(298/Tav)(Pav/760)]- b)
m = sampler slope
b = sampler intercept
I = average chart response
Tav = daily average temperature
Pav = daily average pressure
Sqrt = square root
Example:
m3/min = 1/26.8212((36)[Sqrt(298/291.5)(746.8/760)]-(+3.1104))
m3/min = .0372839 ((36)[Sqrt(1.0222984)(0.9826315)] -3.1104)
m3/min = .0372839 ((36)[Sqrt(1.0045426)] -3.1104)
m3/min = .0372839 ((36)[1.0022687)] -3.1104)
m3/min = .0372839 ((36.081673) -3.1104)
m3/min = .0372839 (32.971273)
m3/min = 1.2292976
ft3/min = 1.2292976 x 35.31 = 43.406498
Total ft3 = ft3/min x 60 x hours that sampler ran
Let's say our sampler ran 24 hours (end ETI reading - start ETI reading)
** Make sure ETI is in hours otherwise convert to hours **
Total ft3 = 43.406498 x 60 x 24 = 62,505.355 ft3
Total m3 = 1.2292976 x 60 x 24 = 1770.1885 m3
