3.1 Function description
The QLX3 liquid module can be added to XPR analytical balances to perform automatic dosing. The liquid
dosing head is attached to the liquid module and located inside the weighing chamber. The height of the dosing
module is adjusted manually. The QL3 pump and QLL kit for bottle are completing the system. The QL3 pump
is used to built pressure in the bottle. When pressure is high enough, the micro dispensing valve in the liquid
dosing head opens and liquid can ascend the liquid tube. Several pumps can be connected to the balance
simultaneously
