The maximum filling rate depends on the cylinder volume (see Chapter
31, page 338).
However, in order to ensure uninterrupted dosing, the following points
must be taken into account:
￭ Use the highest possible filling rate in order to keep the filling times as
short as possible. The filling rate should be decreased for viscous liq-
uids.
￭ When you use two buret units with different dosing cylinders, the fill-
ing rate for the larger sized cylinder must be at the minimum:
= filling rate in mL/min for the larger sized cylinder
= filling rate in mL/min for the smaller cylinder
= cylinder volume in mL of the buret unit of the second dosing
device
= cylinder volume in mL of the buret unit of the first dosing
device
Example:
Dosing device 1: volume = 20 mL, filling rate = 50 mL/min
Dosing device 2: volume = 50 mL
Filling rate 2 ≥ 50 mL/min · 50 mL / 20 mL ≥ 125 mL/min
￭ The dosing rate must not exceed 75 % of the filling rate of the smaller
cylinder. These values are listed in the following table, valid at maxi-
mum filling rate:
