Measuring ranges for gases (Promass A)
Measuring ranges for gases (Promass I)
Measuring ranges for gases (Promass X)
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 (liquid): 70000 kg/h
• x = 90 (for Promass F DN 50)
Max. possible full scale value:

=

÷ x [kg/m³] = 70000 kg/h · 60.3 kg/m³ ÷ 90 kg/m³ = 46900 kg/h

Operable flow range
Greater than 1000 : 1. Flows above the preset full scale value do not overload the amplifier,
i.e. totalizer values are registered correctly.
