WebJul 28, 2003 · The volume of air sampled is obtained by multiplying the flow rate by the duration of the sampling. For example, if the pump flow rate is 2 liters per minute and we sample for 2 hours (i.e. 120 minutes), the sample volume is determined by multiplying the flow rate by the sampling time. In this case, 2 lpm x 120 minutes is 240 liters. WebThe sampling pump to be calibrated is attached to the top of a volumetric glass tube containing a small amount of liquid soap. As the pump draws air through the tube, a flat soap bubble is interposed in the flow path. While the air flow causes the soap film to move from one volume mark to another, the travel time is measured with a stopwatch.
