Select: Volume Flow / Norm. Volume Flow / Mass Flow / Density / Temperature1 /
Temperature2 / Pressure / Vortex Frequency / Velocity / Specific Enthalpy / Specific
Heat Capacity / Reynolds Number / FAD / Net Power / Gross Power
Availability of selection depending on meter type and medium configuration.
C2.2.3.2 Pulse Shape
Select: Automatic (constant pulse width based on pulse/pause ratio = 1 at max. pulse
rate) / Symmetric (pulse/pause ratio = 1) / Fixed (Fixed pulse length; set pulse width in
C2.2.3.3)
C2.2.3.3 Pulse Width
Only available, if "Pulse Shape = Fixed" is selected in C2.2.3.2.
Enter pulse width in ms.
C2.2.3.4 0% Pulse Rate
Enter value for 0% pulse rate in Hz.
C2.2.3.5 100% Pulse Rate
Enter value for 100% pulse rate in Hz.
C2.2.3.6 0% Range
Enter value for 0% range in unit according to measurement variable selection.
C2.2.3.7 100% Range
Enter value for 100% range in unit according to measurement variable selection.
C2.2.4 Status Output
Only available, if "Status" is selected in C2.2.1.
C2.2.4.1
Selection can be made, which event will trigger a signal on the status output.
Select:
- Flow Totalizer Overfl.: Signal is sent, when pre-defined flow totalizer value is reached.
Define value in C4.1.2.
- Energy Totalizer Overf.: Signal is sent, when pre-defined energy totalizer value is
reached. Define value in C4.2.2.
- Failure: Status signal is sent in case of failure.
- Function Check: Status signal is sent, if a test function is active.
- Out of Specification: Signal is sent, if measurement is out of specification.
- Type of Fluid (for steam applications): Signal is sent to signalise transition in type of
fluid.
C2.2.4.2 Type of Fluid
Only available, if "Type of Fluid" is selected in C2.2.4.1.
Select (availibility depending on fluid and medium configuration):
- Liquid: Indicates transition of medium to liquid.
- Saturated Steam: Indicates transition of medium to saturated steam.
- Superheated Steam: Indicates transition of medium to superheated steam.
C2.2.4.3 Type of Fluid Epsilon
Only available, if "Type of Fluid" is selected in C2.2.4.1.
Value defines the sensitivity of transition detection.
Enter value between -1.0 (to decrease sensitivity) and +1.0 (to increase sensitivity).
C2.2.5 Limit Switch
Only available, if "Limit Switch" is selected in C2.2.1.
C2.2.5.1 Measurement
Limit output variable can be defined, which will trigger a signal on the status output.
Select: Volume Flow / Norm. Volume Flow / Mass Flow / Volume / Density /
Temperature1 / Temperature2 / Pressure / Vortex Frequency / Velocity / Specific
Enthalpy / Specific Heat Capacity / Reynolds Number / Mass / Norm. Volume / FAD /
Net Energy / Gross Energy / Net Power / Gross Power
The latter five measurement variables are just available if the respective meter type
option was activated and fluid/medium were properly configured.
Availability of selection depending on meter type and medium configuration.
C2.2.5.2 Lower Limit
Enter value for lower limit in unit according to selected limit output variable.
C2.2.5.3 Upper Limit
Enter value for upper limit in unit according to selected limit output variable.
C2.2.6 Invert Signal
Select: On (normally open) / Off (normally closed)
