10. Sampler set-up - proportional-to-flow sampling
10.4 Calculate the counter setting using the
following chart:
1. your pump displacement (from .1 to .4cc's)
2. your sample cylinder volume in cc's (300cc, 500cc, etc.)
3. average flow rate (MMCF per day or MCM per day)
4. sample period in days
5. pulses/volume metered (pulses/MMCF or pulses/MCM)
6. counter setting
pump displacement
sample cylinder size
average flow rate
sample period
pulses per volume metered
Example #1
counter setting =
Example #2

10.5 Adjust the pump volume adjustment knob to
the value used in the calculation in step 10.4.
Sample pump displacement per stroke
.1cc
.2cc
.4cc
10.6 Turn the counter dials to the appropriate num-
ber of pulses you want to count before the sample
pump strokes.
Example: 20 pulses; turn dials to 20.
Press the test button once to load the value into the
memory.

NOTE: If the calculated counter setting is less than 1 or greater
than 99, the pulses per volume metered will need to be adjusted.
This can be programmed in most flow meters to the desired rate.
If the calculated counter setting is less than 1, increase the pulses
per volume metered. If the calculated counter setting is greater
than 99, decrease the pulses per volume metered volume.
