Flow check and flow adjustment of the Particle Monitor and Particle Profiler
It is important to maintain the correct flow rate through the Particle Monitor or Particle Profiler. The
flow rate of the Particle Monitor and Particle Profiler are different.
NOTE: The flow rate of the Particle Monitor is 2.0 ± 0.05 LPM
The flow rate of the Particle Profiler is 1.0 ± 0.05 LPM

The AQS R56 includes a flow adaptor which is fitted on the inlet, for the Particle Monitor it is fitted
above the cyclone as shown in Figure 6-11.
Figure 6-11 When checking the flow rate of the Particle Monitor (left) place the flow measurement adaptor
above the cyclone. The position of the flow adaptor when measuring the Particle Profiler is shown on the
right.

Using the buffer chamber when checking the flow of the Particle Profiler
When measuring (or adjusting) the flow rate of the Particle Profiler it is important to use the buffer
chamber to ensure accurate measurement. The buffer chamber is part of the AQS R56 Zero Filter
and Flow assembly. It is also part of the R20 Service kits. Figure 6-12 shows the buffer chamber
installed between the flow meter and the profiler inlet.
