Calculation example for gas:
• Sensor type: Promass F, DN 50
• Gas: air with a density of 60.3 kg/m
3
(at 20 °C and 50 bar)
• Measuring range: 70000 kg/h
• x = 160 (for Promass F DN 50)
Max. possible full scale value:

Page 100 ff. (“Limiting flow”)
Operable flow range
Greater than 1000 :1. Flows above the preset full scale value do not overload the amplifier, i.e. tota-
lizer values are registered correctly.

Outputs (FOUNDATION Fieldbus)
Output signal
Physical data transmission (Physical Layer Type):
• Fieldbus interface to IEC 61158-2 (MBP)
• corresponds to device profile type 512 of the FOUNDATION Fieldbus specification: type 512 –
standard data transfer (±9 mA, symmetrical), separate supply to field device (4-wire), intrinsically
safe execution of the FF interface, FISCO
• with integral polarity protection
