If not performing a flow verification, restore the sampling hardware to
its original state by removing the flow metering hardware and
reinstalling the PM
10
inlet on the sample tube. Remove the filter
cassette from the Sampler and discard the installed filter.
Perform the temperature verification, pressure verification, and a leak check
before performing the flow verification procedure.
Note
Ensure that the filter cassette carrier previously installed in the
Sampler (which was used to perform the external leak check) remains in the
unit for the flow verification.

While the flow verification procedures are similar for the Partisol 2000
i
and
Partisol 2000
i
-D, since the Partisol 2000
i
-D Sampler uses two flow sensors
to control the sample flows for the PM
2.5
and PM
coarse
flow channels, the
verification procedures are presented for each Sampler.
Note
If you are using a Streamline Pro MultiCal System or other direct
reading flow audit device, follow these instructions. If using a Streamline
FTS, follow the instructions later in the manual. The proper values for the
Streamline FTS constants can be entered into the Sampler for proper
calculation of the measured flow values.
▲
If you are not using the Streamline Pro or FTS systems to audit the flow of
the Samper, you may need to install the flow audit adapter (57-000618)
onto the end of the sample tube (
Figure 7–5
). If you will be using the flow
audit adapter, ensure that you install it onto the end of the sample tube
with its valve in the open position.
Flow controllers require a 15 minute warm-up prior to first reading. All
subsequent readings should be taken 2-3 minutes (minimum)
thereafter.
Use the following procedure to perform a flow audit on the Partisol 2000
i
:
1.
Remove the flow audit adapter used during the leak check and install
the Streamline Pro on the sample tube (
Figure 7–6
). Other flow meters
may require the use of the flow audit adapter (valve open) to measure
flow.
