The full scale values depend on the density of the gas. Use the formula below to calculate the full
scale values:
g
max(G)
= g
max(F)
⋅ ρ
(G)
/ x [kg/m
3
]
g
max(G)
= Max. full scale value for gas [kg/h]
g
max(F)
= Max. full scale value for liquid [kg/h]
ρ
(G)
= Gas density in [kg/m

] at operating conditions
x = 160 (Promass F DN 8...100, M, I); x = 250 (Promass F DN 150...250); x = 225 (Promass E);
x = 32 (Promass A)
Here, g
max(G)
can never be greater than g
max(F)
Calculation example for gas:
• Sensor type: Promass F, DN 50
• Gas: air with a density of 60.3 kg/m

(at 20 °C and 50 bar)
• Measuring range: 70000 kg/h
• x = 160 (for Promass F DN 50)
Max. possible full scale value:
