Input
Measured variable
• Mass flow (proportional to the phase difference between two sensors mounted on the measuring tube to
register a phase shift in the oscillation)
• Fluid density (proportional to resonance frequency of the measuring tube)
• Fluid temperature (measured with temperature sensors)
Measuring range in non-
custody transfer mode
Measuring ranges for liquids
Measuring ranges for gases
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/m³]
g
max(G)
= Max. full scale value for gas [kg/h]
g
max(F)
= Max. full scale value for liquid [kg/h]
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/m³ (at 20 °C and 50 bar)
• Measuring range: 70000 kg/h
• x = 90 (for Promass F DN 50)
Max. possible full scale value:
g
max(G)
=
g
max(F)
·
ρ
(G)
÷ x [kg/m
3
] = 70000 kg/h · 60.3 kg/m³ ÷ 90 kg/m³ = 46900 kg/h
