After starting the system, the average path relationship values are calculated on the basis
of a minimum of 10,000 individual measurements. To collect that amount of data, the
FLOWSIC600 requires approximately 20 minutes of error-free measurement on all paths.
Example:
The FLOWSIC600 makes 10 readings per second for each path, giving 6,000 readings in
10 minutes, and 10,200 in 17 minutes.
Because the path compensation procedure operates in a low (1 to 8 m/s or 3.28 to 26.24
ft/s) and a high (>8 m/s or >26.25 ft/s) gas velocity band separately, the FLOWSIC600
needs to measure 20 minutes within the low and 20 minutes within high velocity range.
When the average path relationships have been established based on the required mini-
mum number of single readings, the path relationships are marked valid (the bit in Reg.
#3003 "System Status" is set to "valid"), and the system is then able to compensate for
path failure.
The variable mean value calculation is turned on at the same time. The default attenuation
constant for this self-learning algorithm (Reg. #7206 "PathCompAverWeight") ensures that
statistical variation is suppressed.
The path relationships for low (1-8 m/s or3.28 to 26.25 ft/s) and high flow velocities (> 8
m/s or >26.25 ft/s) are determined separately (see table below). This improves the result
of the compensation because the path relationships are more stable at higher flow veloci
-
ties. The path relationships are not learned if the flow velocity is below the value in Reg.
#7208 "PathCompClassLo".

Notes
Operation below
"PathCompClassLo"
< 1 m/s
If the flow velocity is below the value specified in
Reg. #7208 "PathCompClassLo", no automatic
path relation adaptation occurs.
In case of failure, the stored path relations for low
flow velocities (1-8 m/s) are used.
Reg. #7208 
"PathCompClassLo"
1 ... 8 m/s
If the flow velocity is above the value
"PathCompClassLo", but below
"PathCompClassHi", continuous calculation and
adaptation of the path relations occurs.
The results are saved in the "low flow" class
registers #7289 - #7292 (path 1-4).
Reg. #7207 
"PathCompClassHi"
> 8 m/s
If the flow velocity is above "PathCompClassHi",
continuous calculation and adaptation of the
path relations occurs.
The results are saved in the "high flow" class
registers #7285 - #7288 (path 1-4).
