2 Design and Function
1 2 3
2.1 Dosing heads and equipment
1 Powder dosing head (e.g. QH008-BNMW)
This head can be equipped with a powder storage container. This is the standard head for powder
dosing.
2 Liquid dosing head (e.g. QL001)
This is the standard head for liquid dosing. It is used together with the pump module and bottle.
3 Manual dosing head (QA000-M)
This head has no powder container and the user has to dispense the powder manually.
Powder dosing head
The spare cap included in the delivery may be used to use the dosing head without a storage vial.
Storage vials and transport boxes need to be purchased separately.
You can print a label containing the powder data stored in the dosing head, affix this label to the
powder container.
Manual dosing head
This head is reduced to a tag that allows to enter substance data and to print respective data.
Powder test head
This head is equipped with a powder storage container filled with calcium carbonate (CaCO3) and a
test function. It dispenses automatically 10 times a defined mass and reports the results. Check the
results of the typical values > repeatability (sd), fine range automated operation and dosing time. If
your instrument didn't pass the tests, inform a METTLER TOLEDO service engineer.
MinWeigh dosing head
The MinWeigh dosing head performs a minimum weight test automatically by placing a test weight
on given tare weights. The procedure will be repeated 10 times to define the automated MinWeigh.
8 Quantos Automated Dosing
2.2 Data stored in the dosing head’s RFID tag
1
Every dosing head is equipped with a integrated RFID tag (1)
which stores and exchanges data with the instrument.
The following data is stored in the RFID tag of the head:
• User data
• This block holds information about the substance such as
the name of the substance, the filling and expiry dates, the
quantity, etc. This data can be edited by the user at any time
and should be entered before using a new head for the first
time to have the data available for reports and labels.
Note for powder dosing heads
The counter for the remaining powder dosing cycles is based on the lifetime limit of the dosing head
(max. 999). With every dosing cycle started, the counter is decreased by 1. If the counter drops to
zero, the head must be replaced. If the powder container of the old head still contains a considerable
amount of powder, you may remove the powder container from the old head and screw it onto the
new one. Just copy the user data and the powder content value from the old head to the new one.
If the remaining quantity of powder is insufficient for the next dosing cycle, a warning message will
appear.

CAUTION
Danger of injuries due to splashing liquids or substances!
The bottle stands during use under 0.5 bar (7 psi) pressure. Liquid splashing out might
harm the user and can damage the device.
1 Do not remove tubes under pressure.
2 Relieve pressure by switching off the insrument, pull out the tube.

3.5.1 Connecting the tubes
Connectors of pump module
The thinner tube is used for transporting liquid from the bottle to the liquid dosing head. The slightly
bigger tube is used for pumping air into the bottle. By adding air, pressure rises in the bottle. When
pressure reaches min. 0.3 to max 0.5 bar (4.4 to 7.2 psi) the micro dispensing valve in the dosing
head opens and liquid can ascend the liquid tube. The two tubes are further referred to as liquid tube
and air tube.
