10.4 Calculate the counter setting using the
following chart:
1. your pump displacement (from .1 to .4cc’s) = a.__________
2. your sample cylinder volume in cc’s (300cc, 500cc, etc.) = b.__________
3. average flow rate (MMCF per day or MCM per day) = c.__________
4. sample period in days = d.__________
5. pulses/volume metered (pulses/MMCF or pulses/MCM) = e.__________
6. counter setting = a x c x d x e
(b)
Example #1:
English Gas Flow
Units
Example #2:
Metric Gas Flow
Units
pump displacement (a.) = .2cc .2cc
sample cylinder size (b.) = 300cc 300cc
average flow rate (c.) = 10 MMCF per day 10MCM/day
sample period (d.) = 30 days 30 days
pulses per volume metered (e.) = 100 pulses/MMcf 100 pulses/MCM
Example #1
counter setting = .2cc x 10 MMcf per day X 30 days X 100 pulses per MMcf =
20 pulses
300 cc
Example #2
counter setting = .2cc x 10 MCM per day X 30 days X 100 pulses per MCM =
20 pulses
300 cc
