Introduction
You can use the TSI 440 flowmeter or a single rotameter to measure the flow rate of your particle monitor.

Enter service mode so any fluctuations in the data caused from this activity can be excluded from air quality reports.
-
-
-
The flow rate of the particle monitor must be 2.0 LPM ± 0.05 (between 1.95 and 2.05 LPM).
-
A constant 2.0 LPM flow is essential to ensure the sharp cut cyclone is separating out the correct particle size for measurement, eg. PM10 or PM2.5.
-
-
-
Remove the TSP head from the top of the sharp cut cyclone and attach the flow adaptor on your flow assembly.
-
Attach the flow assembly to a 0-2.5 LPM volumetric flow meter.
-
If using the R8 flowmeter, connect the assembly to the top port of the flowmeter (negative flow).
-
Ensure the flowmeter is on a steady surface before reading the flow rate.
-
-
-
If the flow isn't correct, adjust the sample flow valve which is located on the face plate of the pump module, until the flow reads 2.0 LPM ± 0.05 (between 1.95 and 2.05 LPM).
