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

Calculation example for gas
• Sensor: Promass S, 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 S, DN 50)
Maximum possible full scale value:
max(G)
=
max(F)
· ρ
G
: x = 70
000 kg/h · 60.3 kg/m³ : 90 kg/m³ = 46
900 kg/h
Recommended measuring range
Operable flow range
Over 1000 : 1.
Flow rates above the preset full scale value are not overridden by the electronics unit, with the result
that the totalizer values are registered correctly.
