To calculate the measuring range, use the Applicator sizing tool (® ä 108)
Calculation example for gas
• Sensor: Promass E, DN 50
• Gas: Air with a density of 60.3 kg/m
• Measuring range (liquid): 70 000 kg/h

• x = 125 kg/m (for Promass E DN 50)
Maximum possible full scale value:
× r : x = 70 000 kg/h × 60.3 kg/m
g = g

Recommended measuring range
"Flow limit" section (® ä 101)
Greater than 1000 : 1. Flow rates above the preset full scale value do not overload the amplifier so
the totalized values are registered correctly.

Output

2-wire
• Current output 1: 4-20 mA HART, passive
• Current output 2: 4-20 mA, passive
• Lower-range value, full scale value and time constant (0.07 to 999 s) can be set
Depending on the interface, failure information is displayed as follows:
• Current output
– Failsafe mode selectable (in accordance with NAMUR Recommendation NE 43):
Minimum alarm: 3.6 mA
Maximum alarm (= factory setting): 22 mA
– Failsafe mode with user-selectable value: 3.59 to 22.5 mA
• Local display
– Status signal (in accordance with NAMUR Recommendation NE 107)
– Plain text display
• Operating tool via HART communication or service interface (CDI)
– Status signal (in accordance with NAMUR Recommendation NE 107)
