Measuring range for gases
The full scale value depends on the density and the sound velocity of the gas used and can be
calculated with the formula below:
 = minimum ( · ρ
max(G) max(F)
 Maximum full scale value for gas [kg/h]
max(G)
 Maximum full scale value for liquid [kg/h]
max(F)
 <  
max(G) max(F)
ρ Gas density in [kg/m³] at operating conditions
G
x Constant dependent on nominal diameter
c Sound velocity (gas) [m/s]
