Process of detecting a load
To count a load, you have to go through a certain sequence of angular
positions. In addition, minimum times must be reached in order to exclude a
multiple count.
For a slurry tanker with level indicator (pointing to the left) this looks like the
following example:
The counter is mounted directly on the level indicator, the angle of the level
indicator is identical to the angle of the device. The angle is measured and
evaluated by the device.
A tanker starts with the first load, the level indicator is set
to "empty", the angle is below the middle. The counter is in
the "empty" state.
The filling process starts, the level indicator turns
upwards.
If the tank is approximately half full, the angle set in
parameter "A1" is exceeded. Now the time "t1" set in the
parameter starts to run. This status is indicated by the up
arrow.
The filling process continues. The counter checks whether
the pointer is above the angle "A1" at least the entire time
"t1". If this is the case, the filling is considered completed.
The counter changes to the status "full".
The tanker moves to the unloading point.
The unloading process starts, the level indicator turns down.
If the tank is approximately half empty, the angle fall
below the setting in parameter "A1". Now the time "t2" set
in the parameter starts to run. This status is indicated by
the down arrow.
The unloading process continues. The counter checks
whether the pointer is below the angle "A1" at least the
entire time "t2". If this is the case, the application is
considered completed, a load is counted. The counter
changes to the "empty" state and the sequence starts
again.
