10.1.2 Sampling types
The timer function in the control system makes sampling at defined times possible. Depending on
the measured flow, samples can be taken in proportion to the quantity and flow.
Sampling can also be triggered by an external signal, for example in the event of limit value
violation.

Fig. 67: Sampling types
Time proportional:
A constant sample volume is taken at constant time intervals.
Quantity proportional:
A constant sample volume is taken at variable time intervals.
Flow proportional:
A variable sample volume is taken at the same time intervals.
10.1.3 Sample distribution
The sample liquid is distributed into the individual bottles by means of a tap (item A). In addition to
a 30 l and 60 l composite container, various bottle distributions are available. The distribution
version can be replaced or changed easily without the need for tools. The ASP station 2000 allows
flexible configuration of the sample distribution. Individual bottles and bottle groups can be freely
defined for the main, switching and event programmes. Individual bottles are located in two
separate bottle trays (item C). Grips on the bottle trays make transportation easy and practical.
