Measuring range 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:
= Max. full scale value for gas [kg/h]
= Max. full scale value for liquid [kg/h]
ρ
(G)
= Gas density in [kg/m
3
] under process conditions
Calculation example for gas:
• Sensor type: Promass E, DN 50
• Gas: air with a density of 60.3 kg/m
3
(at 20 °C and 50 bar)
• Measuring range: 70000 kg/h
Max. possible full scale value:
Recommended full scale values:
See Page 55 (“Limiting flow”)
Operable flow range Flowrates above the preset full scale value do not overload the amplifier, i.e. the totalizer
values are registered correctly.
Input signal Status input (auxiliary input):
U = 3...30 V DC, R
i
= 5 kΩ, galvanically isolated.
Configurable for: totalizer reset, positive zero return, error message reset, zero point
adjustment.
