E05 Calculation method
The TME400 enables calculation of gas parameters, particularly the
compressibility coefficient according to various methods. These
methods must be adjusted in coordinate E05 with the corresponding
coefficient. Available for selection:
0 Constant compressibility (default
1 Gerg88S
2 AGA8 GROSS method 1
3 AGA8 GROSS method 2
4 AGA8 NX19 DV
5 AGA8 NX19 Rho
The simplest option is to set to the compressibility to constant. This
is correct if you always work with the same measuring gas and know
the compressibility coefficient. Enter this compressibility coefficient in
E02.
The compressibility coefficient constant is set to "1" for an ideal gas
(e.g. gases at low pressure).
Complete gas analyses are not necessary for any other gas models,
but knowledge of additional gas parameters is necessary. Depend-
ing on the model, this must be entered in coordinates E07 to E12:
E07 Calorific value Ho n KWh/m3
E08 Standard density Rho n Kg/m3
E09 Density ratio DV
