6.5.6.2
Flow adjustment of Particle Monitor
The flow rate of the Particle Monitor must be 2.0 LPM ± 0.05 (between 1.95 and 2.05 LPM)
Figure 6-13 The flow rate of the Particle Monitor is set by adjusting the purge and exhaust valves
The flow rate of the Particle Monitor must be 2.0 LPM ± 0.05 (between 1.95 and 2.05 LPM)
Fully close the purge valve by pushing the valve handle towards the module
Adjust the exhaust valve until the flow reads 2.2 LPM
Adjust the purge valve until the flow reads 2.0 LPM ± 0.05
The final adjustment can be a little tricky, turn the purge valve slowly. If it is not possible to reach 2.2
LPM at step 2 then there may be a leak or the pump might need to be replaced.
6.5.6.3
Flow adjustment of Particle Profiler
NOTE: It is important to use the buffer chamber when measuring or adjusting the flow rate of the
Particle Profiler. Section 6.5.6.1
Figure 6-14 The flow rate of the Particle Profiler is set by adjusting the flow adjustment valve
The flow rate of the Particle Profiler is adjusted to 1.0 LPM ± 0.05 LPM using the flow adjustment
valve as shown in Figure 6-14.
