Example for Bi-directional flow (NAMUR):
Analog output 1 To set the current output 1. This output provides HART communication.
Analog 1 select Select: Mass flow (0), volume flow (1), density (2), Temperature (3),
Concentration meas (4), Net flow (5), None (6)
Numbers may be displayed if selected via HART.
If None is selected, output is 4 mA, HART communication is available.
Analog 1 alarm out
(Detailed setup, configure
output/input) If NAMUr is selected (meter without option /NA):
<3.6 mA, >21 mA, Hold, Measured value
If NOT NAMUr is selected (meter with option /NA):
<2.4 mA, <3.6 mA, <4 mA, >21 mA, >21.6 mA
Analog 1 low lMT
(low limit)
(Detailed setup, configure
output/ input)
The alarm is active if the
measured value is lower than the
low limit. If NAMUr is selected (meter without option /NA):
Measuring range from 3.8 - 20.5 mA
Alarm level: < 3.6 mA or > 21.0 mA
If NOT NAMUr is selected (meter with option /NA):
Measuring range from 2.7 - 21.3 mA
Alarm level: < 2.4 mA or > 21.6 mA
Analog 1 high lMT
(high limit)
(Detailed setup, Configure output/
input)
The alarm is active if the
measured value is higher than
the high limit. If NAMUr is selected (meter without option /NA):
Measuring range from 3.8 - 20.5 mA
Alarm level: < 3.6 mA or > 21.0 mA
If NOT NAMUr is selected (meter with option /NA)
Measuring range from 2.7 - 21.3 mA
Alarm level: < 2.4 mA or > 21.6 mA
