7 Intake Hose Connection The volume control tube is where the intake hose is connected to
the sampler. This stainless steel tube is raised or lowered
manually using fitting to set the sample volume (see FIGURE 1-3
on page 1-6).
8 Wiring Connects electricity to the rods for sampling. When replacing
metering chamber, these rods can be easily disconnected.
9 Nuts to adjust volume To adjust sample volume, twist top nut while holding bottom nut
in place. Hand tightening works for many applications, but a
wrench is advised.
10 Metering Chamber This chamber is where the sample liquid is drawn into before
dropping into the final container. The rods inside are raised and
lowered to the sample volume desired.
11 Battery Standard on all samplers. The PVS4100 battery is 15 lbs, 17AH.
The PVS4120 battery (shown) is 4 lbs, 7 AH.
12 Multi-Function Input Controller This is where sampler is controlled and programmed.
13 Sinker. Optional Strainer. Keeps the end of the intake tube in the source liquid. Optional
strainer can raise collection point above sinker.
14 Intake Hose Standard samplers come with 25 Feet of 3/8” ID PVC tube.
15 Stepper Assembly Moves the distributor arm for multiple bottle configurations. This
is not present on composite (single bottle) samplers.
16 Distributor Arm Dispenses liquid into bottles. Moves to next bottle after
sampling. On composite (single bottle) samplers, this is replaced
with discharge tube.
17 Sample Container(s) The container(s) that the sample is deposited in can be made
from a variety of materials, shapes, and sizes. In discrete
samplers, there is a distributor arm that deposits samples into
multiple containers.
18 Retaining Plate Holds sample bottles down tightly (discrete samplers only).
19 T-Bar This bar is needed to hold the retaining plate down. It is
imperative that the bottles do not lift up even a little bit, as they
can interfere with the mobility of the distributor arm (discrete
samplers only).
20 Bottle-Guide Notch This notch is the location of bottle number one. It lines up the
middle section of the sampler so that the distributor arm can be
placed at the same location.
