2.1.1 Unloading :
• Ground the vehicle.
• Connect the Centrex multi 2 unit to the compartment to
be emptied via a DN80 hose. Then open the valve.
• Select the storage tank to be filled.
• If necessary, reset the meter to 0 and put a ticket in the
printer.
• Starting-up of the pump.
• The product passes through the pump filter 1.
• The filter 4 allows to protect the meter.
• The gas separator 5 allows the air produced to be eva-
cuated in case of stock shortages.
• The sight glass 6 allows checking that the gas separator
works properly (no continuous flow of liquid).
• The degassing line 7 carries out the gas caught by the gas
separator and move them after the meter in the discharge
line.
• The no return valve 16 avoids any liquid return from going
back to the gas separator.
• The setted valve 8 allows the degassing of the product
and prevents its return to the pumping zone.
• The degassed product passes into the meter 14 with data
recorded on the ticket or via electrical signals depending
on the version.
• Once the compartment is empty, the assembly will fill
with air and the meter will stop.
