HEADING function determines the label for the total product
loss, total waste, etc. result based on the externally measured
sample flow input value, which is sent to the BioTector as an
analog input signal, if this option is installed into the system. This
parameter is an editable text with a maximum size of 8
characters. The default text for HEADING is “TOC kg/h”.
DETECTION TIME function defines the time (25s by default)
system calculates the “Exponentially Weighted Moving Average”
value of sample flow input, just before the sample injection into
the reactor.
The first parameters of STREAM 1-3 functions define the full
scale (in m
3
/h) of the sample flow meter analog input signals for
streams from 1 to 3 in systems built with this option. The second
parameters (1.00 by default) are the stream specific FACTORS.
For instance, if the TOC FACTOR is programmed as “3” for
STREAM 1 in COD Program menu, and the preferred HEADING
to be displayed and sent as 4-20mA signal is COD in kg/h, the
stream specific FACTOR can be programmed as “3” for
STREAM 1 in the Flow Program menu.
When the display of the Flow Program is activated with the
DISPLAY function above, BioTector calculates the programmed
total product loss, total waste, etc. value (e.g. TOC in kg/h) using
the measured TOC result and the recorded stream specific
Sample Flow value as follows:
TOC “kg/h” = [ (TOC Result “mgC/l”) / (Sample Flow “m
3
/h”) /
1000] * FACTOR
When activated, the recorded sample flow values (FLOW in
m
3
/h) and the calculated total product loss, total waste, etc.
values (e.g. TOC in kg/h) are displayed in analysis result screen
and in the reaction archive menus.
