"Tank full" detection functionality
"Tank full" detection takes place via two different operating principles:
A)
Fuel returns in the overflow pipe, through the fuel station and then back into the fuel container.
As soon as the detector detects fuel in the flowback line, this is a sign that the tank is full.
This setting applies when the Stop-Signal parameter is set to 2-line flowback.
This option is not available for bag tanks as they do not use flowback lines.
B)
The second detection principle for "tank full" does not use the signal on the fuel flowback line,
but only the fuel flow rate is evaluated.
With bag tanks, as soon as the tank becomes full, the pressure rises slightly. This has the
consequence that the fuel flow drops slightly.
In a normal tank, the same happens as soon as fuel flows into the tank overflow line. Here, too,
the pressure in the tank rises slightly, causing the fuel flow to drop slightly.
The fuel station software evaluates the fuel flow with appropriate algorithms and can derive the
"tank full" signal from it.
The evaluation is not based on the absolute flow, but on its relative change.
This setting applies when the Stop-Signal parameter is set to "Flow/Pressure".
This option is automatically enabled for bag tanks.
The type of "tank full" detection assigned to the model memory can be set in the Fill-Settings menu
