4.2 Gas flow meters and flow measurement
Accurate and precise flow rate measurement is critical for AQM 65 service and calibration. Flow rates
can be measured and reported in a number of different ways. It is important to understand the
terminology and equipment associated with flow rate measurement.
Aeroqual recommends either the Bios Defender DryCal or the Aeroqual R7 flow meter, these can both
be used to measure gas flow and Particle Monitor flow.
Aeroqual measures standard flow; the Aeroqual standard conditions are 21.1
o
C and 101.3 kPa.

recommends the Bios DryCal or the TSI 4140 (AQM R7)
