The definition of word to be used in this manual.
Measuring gas
Target gas to measure in sample gas
Base gas
Remaining gas excluding measuring gas in sample gas.
Reference gas
The gas to be used as the basic standard gas to measure gas
concentration.
Normally the base gas is used as reference gas.
Reference gas
calibration
(REF CAL.)
Adjusting work of reading when reference gas concentration is
measured.
The definition of word to be used in specification sheet.
Vol %
This is the unit shown by percentage for how much a specific
substances(or gas) in a volume is occupied in that volume.
p p m
This is the unit showing a volume at a part per million.
(1 vol% = 10,000ppm)
% LEL
This is the unit to define the lower explosive limit of combustible
gas as 100%
mg/L
This is the unit showing a weight in 1 liter of objective gas for
measurement. The value is based on 101.3kPa at 20℃.
MJ/m3
Gross
This is the unit of calorie and is shown as Gross Corific Value
0℃. The Gross Calorific Value 0℃ is a unit of calorie commonly
used in city gas companies, which shows the generating calorie
when 1m3 gas is made perfect combustion at normal
condition(0℃, 1 atm).
The gas combustion produces water vapour, but the Gross
Calorific Value applies the one adding the calorie of water
vapour (latent heat)
MJ/m3
Net
This is the unit of calorie and is shown as Net Corific Value 0℃.
The Net Calorific Value 0℃ is a unit of calorie commonly used
in city gas companies, which shows the generating calorie when
1m3 gas is made perfect combustion at normal condition (0℃,
atm).
The gas combustion produces water vapour, but the Net
Calorific Value applies the one adding the calorie of water
vapour (latent heat)
Gross calorific value = Net calorific value + latent heat
