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)

Calculation example for gas
• Sensor: Promass I, DN 50
• Gas: Air with a density of 60.3 kg/m³ (at 20 °C and 50 bar)
• Measuring range (liquid):70
000 kg/h
• x = 90 kg/m³ (for Promass I, DN 50)
