Instructions for System Selection
●
The quake-proof type gas calorimeter is always equipped with the density meter.
●
The CM6G Gas Calorimeter controls the flow rate under a constant differential pressure. In
the calorific value measurement, if the density of a sample gas changes, a flow rate error
proportional to the reciprocal of the square root of the density of the sample gas,
1/ ρ
g
,
will be generated, which directly affects the calorific value. Therefore, density compensation
is required using a density meter.
For the WI measurement, a density meter is not required since the WI is a value
proportional to
1/ ρ
g
.
