5.3.5.4 General procedure during the gauging process
Dead volume calculation:
The vehicle chamber is emptied down to the minimum level (this level is
configured in the gauging unit (cf. "Settings": min. height [mm])).
The process of measuring the dead volume plus the pipe volume is then
started.
As soon as the float gauge reaches the resting place of the dipstick, the
gauging unit starts to pump the water out of the pipe at timed intervals
until the level sensor on the gauging unit relays the message that there is
no more water in the chamber.
IMPORTANT!
The connecting hose must have a steady gradient to the gauging unit.
Pipe volume calculation:
The vehicle chamber is refilled to 100 mm above the dipstick's minimum
level.
The bottom valve is then closed and the water is pumped out of the pipe
at timed intervals until the level sensor on the gauging unit relays the
message that there is no more water.
The mechanical shut-off valve (API coupling) must then be closed manu-
ally.
In automatic mode, the shut-off valve (API coupling) is not closed when
the pipe volume is being calculated. Both the pipe and the IN hose are
then filled and are emptied again after the measurement has been taken.
The IN hose is therefore empty at the end of the gauging process and
can be connected to the next chamber immediately for the next gauging
process.
The gauging unit then opens the bottom valve and the pipe is filled.
The pipe volume is calculated by means of the dipstick gauge difference.
