Measuring ranges for gases
The full scale values depend on the density of the gas and can be calculated with the
formula below:
max(G)
=
max(F)
· ρ
G
: x
max(G)
Maximum full scale value for gas [kg/h]
max(F)
Maximum full scale value for liquid [kg/h]
max(G)
<
max(F)
max(G)
can never be greater than
max(F)
ρ
G
Gas density in [kg/m³] at operating conditions
x
