Operation principle

The sampling cycle from a vacuum sampler:

•

CLOSING PINCHER:

the pincher squeezes the silicone hose air

tight.

•

PURGE

: the air pump starts and generates pressure in the sample

chamber. From the end (inlet) of the suction hose air bubbles will
escape. Which is a sign the ‘old wastewater’ has left the suction
hose.

•

SUCTION:

the air pump changes rotation and a vacuum is created

inside the sample chamber. Wastewater will be sucked up
through the suction hose until it reaches the level pins. If the pins
aren’t reached within a programmed time (

default 30 sec.

) the

sampling system will count an error sample and will wait until the
next sample must be taken. After (

default setting 3)

error samples

the sampling system will switch in alarm.

•

DOSE

: The level switch changes the rotation direction of the

pump. This creates pressure in the sample chamber and will blow
the excess volume back through the suction hose. After a short
period (

default 10 sec.

) air bubbles escape from the end (inlet) of

the suction hose.

•

PINCHER OPEN:

the pincher opens and the sample will drop to the

container. After several seconds the air pump stops and the cycle
is complete. The sampler waits a minimum of 1 minute* (due to
cooling period air pump) till the next automatic sample is taken.

*

All vacuum samplers have a 1 minute pause time between two
taken samples to give the air pump time to rest / cool.

4.4

Installation instructions

Follow the following procedures during installation

•

Connect the suction hose to the supplied suction hose coupling.
Feed the hose through the inlet and fasten the gland air tight.

•

Mount the end (inlet) of the suction hose on a fixed

representative turbulent point to sample homogeneous

wastewater. Ensure the suction hose is always emerged in the
wastewater / medium.
