Parameter of the gas

 

Various physical properties of the gas which make the detection and determination / 
calculation more elaborate than the flow rate determination of liquids must be taken 
into account for the flow rate measurement of gases. The key parameters for the flow 
rate measurement of gases are summarized below; in the process, differentiation 
takes place between values measured directly, such as the individual gas compo-
nents and derived values. Normally, gas models are required for the calculation of 
derived values which are also briefly described. 
 
 
 

7.1  Direct gas parameters 

Ultimately, the energy content of the gas is essential in the flow rate determination of 
natural gas. This is determined in various models. In the process 

–

 depending on the 

model 

–

 only a few parameters are required in part (e.g. for GERG 88 S calculation, 

see below). This includes calorific value and (standard) density and the share of CO

,

 in the gas composition. The gas components are specified in "BA Compo-

nents mode".
