Measuring ranges for gases
The full scale values depend on the density of the gas and can be calculated with the formula below:
 =  · ρ : x
max(G) max(F) G
 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

Calculation example for gas
• Sensor: Promass E, 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 = 125 kg/m³ (for Promass E, DN 50)
