Function
Sampling takes place in four steps:
1

A0022647
1. Blow clear
The vacuum pump blows the suction line clear via the dosing system.
2. Intake
The "Airmanager" (pneumatic control unit) switches the air path of the vacuum
pump to "intake". The sample is drawn into the dosing beaker until it reaches the
conductivity probes of the dosing system.
3. Dose
The intake process ends. Depending on the position of the dosing tube (item D), the
excess sample liquid flows back to the sampling point.
4. Drain
The hose clamp is opened and the sample is drained into the sample bottle.
3.3
Dosing system
The sample liquid is extracted discontinuously by a vacuum system. The vacuum system in the
ASP Station 2000 RPS20B consists of the following components:
• Vacuum membrane pump
• Non-wearing, “Airmanager” pneumatic step control unit
• Dosing system
