In order to ensure proper operation of the Sampler, periodic flow
calibrations may be required. Before performing flow calibrations, refer to
local agency requirements and the U.S. EPA 2.12

for guidance.
The flow calibration procedures for the Partisol 2000
i
and the Partisol
2000
i
-D are similar. The Partisol 2000
i
contains a single flow sensor,
operating at a default flow rate of 16.7 L/min. The Partisol 2000
i
-D
contains two flow sensors, with the high flow sensor operating at a flow rate
of 15 L/min and the low flow sensor operating at a flow rate of 1.67 L/min.
The calibration procedures that follow can be used for both Partisol
Sampler models.
The calibration of the flow controllers in the Partisol Samplers can be
performed using either a three point calibration or a five point calibration
for each flow sensor. The procedure for a three point calibration is
described in this manual. To perform a five point calibration, the same
basic procedure is followed, with the difference being the use of two
additional calibration setpoints. Refer to “
Flow Calibration Setup
” on page
9-26
to convert the Sampler from a three point calibration to a five point
calibration.
If you are using the Streamline FTS Flow Transfer Standard to calibrate the
flow of the Partisol Sampler, perform the following steps to enter the m
and b constants from the FTS sensors into the Sampler. This will allow the
operator to enter the sensor pressure drop (in inches of H
2
O) and the
Sampler will then calculate the actual flow automatically.
Enter the m and b constants for the FTS sensor(s) into the Sampler. If the
Sampler is a Partisol 2000
i
, enter a single set of constants. If the Sampler is
a 2000
i
-D, enter constants for two flow sensors. To use the FTS as the
calibration device, use the following procedure.
