The maximum filling rate depends on the cylinder volume (see Chapter
31, page 406)
.

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:
