Calculation example for gas
• Sensor: Promass F, 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 F, DN 50)
Maximum possible full scale value:

Operable flow range
Over 1000 : 1.
Flow rates above the preset full scale value do not override the electronics unit, with the
result that the totalizer values are registered correctly.

Physical interface
In accordance with EIA/TIA-485-A standard
Terminating resistor
• For device version used in non-hazardous areas or Zone 2/Div. 2: integrated
and can be activated via DIP switches on the transmitter electronics module
• For device version used in intrinsically safe areas: integrated and can be
activated via DIP switches on the Safety Barrier Promass 100
Signal on alarm
Depending on the interface, failure information is displayed as follows:
