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

Calculation example for gas
• Sensor: Promass Q, DN 50
• Gas: Air with a density of 60.3 kg/m³ (at 20 °C and 50 bar)
• Measuring range (liquid): 80
000 kg/h
• x = 100 kg/m³ (for Promass Q, DN 50)
