Virtual Calculation Channels
The tables below are a summary of the different abbreviations used in the
PARAMETER menu of the virtual channels and the different inputs from channels A
and B required to obtain various readings.

Example 1:
The difference of the volume flows (respectively the difference volume) of the channels A and B
shall be determined. The quantity of measurement of channel A can be: volume flow, or mass flow,
or heat flow. The quantity of measurement of channel B can also be the volume flow, or the mass
flow, or the heat flow. The two quantities of measurement might be different (channel A = heat flow;
channel B = volume flow).
Example 2:
For determining the heat flow difference, the quantity of measurement must be the heat flow for both
input channels A and B.
+Cut-off Flow
1.00 m3/h
-Cut-off Flow
-2.50 m3/h
Two cut-off flows can be defined for each calculation channel:
+Cut-off Flow:
In this example all positive calculation
values, falling below this threshold, will
be set to 0.00.
−
Cut-off Flow: In this example all negative calculation
values, rising above this threshold, will
be set to 0.00.
That means for this example: All calculation values ranging
between –2.5 ... 1.0 m³/h will be negated.
Store Meas.Data
>NO< yes
...
The options for the storage or the output of measured values
can be set in the same way as for the physical channels.
As previously explained, the calculation channels are not filtered, therefore the
dialogue box for the setting of the damping has been removed from the menu.
