Section 1. Product Overview

1.1 Introduction

The PVS4100, PVS4120 and PVS4150 Portable Samplers are automatic liquid
samplers for water and wastewater applications. PVS Samplers are capable of
gathering fluid automatically from a variety of sources, including containers,
open channels, sewers, pipes, and any open source of water.

Samplers are designed for reliable unattended sample collection. Portable units
are capable of keeping the temperature of the deposited liquid at 4ºC (39.2ºF)
for up to 24 hours using crushed ice or ice packs until the samples are gathered
and brought back to the laboratory for analysis.

There are a variety of methods for depositing samples. Composite sampling is
used where samples are deposited, over time, into one container. Discrete
systems are used when multiple bottles are needed. These are also called
“sequential” systems, and involve a stepper with distributor arm which
dispenses the liquid into a bottle, then moves to the next bottle.

Operating temperature for portable samplers is 10ºC to 50ºC (50ºF to 122ºF),
adaptable down to 0ºC (32ºF) upon request.

Samples can be triggered by a variety of means. The internal clock on the
controller can be set to sample based on time/day (e.g. sample every hour).
There are also a variety of external inputs that can be connected to control
sampling using the optional external signal cable. Pulse count is useful for
sampling after a certain number of pulses have been reached (e.g. using a rain
gauge to trigger sampling). The 4-20 mA option is useful for flow-based
sampling (e.g. using a flow meter to trigger sampling after a certain volume of
water has passed by). External contact is used to control the sampler from
another data logger or PLC, and is useful when full external control is desired.
Level control is the option to choose when the application has starts and stops
(e.g. using a float switch to trigger sampling when water is present, then stop
sampling when the water drops below the set level).

When sampling is initiated, liquid travels through the intake tube into the
metering chamber. The amount of water taken is set mechanically using the
liquid sensing rod and the volume control tube, which means sample accuracy
is precise every time, usually within +/- 2% or +/- 2ml.

Once the pre-set amount has been reached, all excess liquid is purged from the
system, and the sample is dropped into a container. Sample containers range
from 500 ml (500 cc or 2 cup) wedges in discrete systems, to 9 liters (2.3
Gallon) containers for composite systems.

Intake tube is offered in either 3/8” (9.5 mm) ID or 5/8” (15.9 mm) ID, and can
be either Nylon-reinforced PVC or Teflon-lined PVC. Transport velocity varies
depending on height and distance being sampled. For most situations the
sampler pulls at over 1.5 m/s (5 ft/sec). For an in-depth speed chart, refer to
Section 1.3.7 Sample Transport Velocity

on page 1-15.

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.

TABLE 1-3. Vacuum System Features

Number Item Description

1 Solenoid Valves Control the air flow from pump to sampler, either purging or

sucking.

2 Pump Located behind a sheet of metal, the pump does not come into

contact with any liquid whatsoever. It does all the drawing and
purging through using a vacuum and compressor.

3 Touchpad Controller Controls sampler program and offers status feedback on LCD.

4 Sample Distributor Rotates distributor arm between multiple discrete containers.

5 Distributor Arm Dispenses liquid from metering chamber into discrete container.

6 Discrete Sample Containers Multiple containers, always in a quantity divisible into 24

1.3.7 Composite and Discrete Overview

Discrete Sampling (PVS4100 and PVS4120 only) is sampling wherein
samples are taken into more than one container. Inside of the cooling chamber
is a stepper assembly which revolves 360° and delivers samples into separate
containers, ranging from 8 to 24 bottles. Discrete sampling is beneficial in
situations where change over time needs to be measured, such as measuring
different water characteristics over 24 hours. Labs and monitoring personnel
tend to rely on discrete portable sampling.

1-14

Section 1. Product Overview

Composite Sampling is for drawing water samples into one large container.
This is the simplest way of taking samples and typical for most situations
where a sampler is set up to measure effluent in one location. It is also
significantly less expensive than discrete sampling.

1.3.8.1 Using Velocity to Calculate Purge Time

Purge time of the sampler needs to be programmed based on the length of hose
and the velocity at which the liquid will travel through the hose. The formula is
l / v = p (length / velocity = min. purge time). Adding a few second to the
purge time is recommended to ensure the line is fully cleared of any
obstructions.

Example: 100 ft of hose, at 5 ft/sec, requires a minimum 20 second purge time.
100 / 5 = 20 seconds. The number input for purge time should be a minimum
of 20, but preferably 24.

Standard purge time for 25 ft of intake tube is 10 seconds. Although a standard
25 ft hose will sample in less than 4 seconds, 10 seconds is the minimum
recommended for proper clearing of the line.

1.3.8.2 Horizontal/Vertical Combinations

The velocity charts above measure only horizontal or only vertical. Most
applications will have combinations of both. With 200 feet of intake tubing,
PVS Samplers are capable of drawing a sample above 2 ft/sec at 20 feet of
vertical. At 23 feet of vertical with 200 feet of intake tubing, sampling may or
may not be successful, depending on altitude and other factors. For more

Scientific applications engineer.

1.3.9 Special Systems

1.3.9.1 5/8 Systems

In applications with large particles or materials in the source liquid, a 5/8” ID
system will help prevent clogging. The added diameter adds 66% more volume
to the entire system. As of 2010, both composite and discrete samplers are
available in 5/8”. Smaller pump systems (PVS4120) have minimal capacity
running the larger volume of the 5/8” ID so the larger pump systems
(PVS4100) are recommended.

For a sampler to increase to a 5/8” ID, the following parts and components are
changed to allow for more volume: intake tube, volume control tube, all
fittings, metering chamber, metering chamber lid, discharge tube, sample
container cover, sinker or strainer, and the distributor assembly (for discrete
models).

1.3.9.2 MISA Systems – Teflon and Glass

Section 1. Product Overview

In applications wherein the water sample must be prevented from coming into
contact with any plastics, a MISA system is recommended. For example, when
testing for acid/base/neutral extractable organics and pesticides, the MISA
system will keep the final sample clean from any contaminants.

MISA stands for “Municipal/Industrial Strategy for Abatement,” and includes
changing all “wetted” components of the sampling system, i.e., everything that
comes in contact with the final sample. The chart below outlines the key
changes made to the sampler for a MISA system.

1.4 Portable Sampler Model Selection Guide

PVS Samplers come in a variety of models designed for variations in weight,
pump strength, battery, larger intake hose (5/8” ID), ease-of-transport, fitting in
manholes, discrete or composite sampling, protection rating for dust and water,
signal options, and budgets.

1-18

Section 2. Installation

2.1 Cabinet Positioning

Place the sampler on a level surface as close as practical to the sample source.
Refer to the speed charts for maximum expected lift and draw. Manhole
installation may require 3-point suspension harness.

Sampler must be located above sample source, or liquid will flood the machine.
For situations where this is not possible, please contact a Campbell Scientific
application engineer for solutions on pressurized sources.

FIGURE 2-1. Sampler Installation

Section 2. Installation

2.2 Intake Hose

Ensure the intake hose is submerged at all times throughout different flow
velocities.

CAUTION

Twenty-five feet of intake hose is provided with the
sampler. Shortening the hose is not recommended since
this length of hose provides sufficient back pressure to the
metering chamber, allowing the pump to efficiently expel all
solids into the sampler container. Coil any excess intake
hose in a manner to provide natural drainage away from
the sampler. To install intake hose, heat the end in hot
water and slip over volume control tube. Secure with hose
clamp provided.

Sample line should be routed so that it has a near continuous slope from the
sampler to the source liquid. This will help keep the sample line cleared and
fully drained. All excess line should be coiled neatly and without any vertical
loops.

2.3 Sinker / Strainer

Sinker or sinker/strainer is intended to keep sample line fully submerged in the
source liquid. A sinker/strainer should be used in situations with material that
clogs up a normal sinker, or where the standard sinker could stir up bottom
sediment.

Lead Sinker: SAM-23-28-01 Stainless Steel Sinker/Strainer: SAM-23-28-11

2.4 Storage

If the sampler is not to be used for an extended period of time, store the unit in
an upright position in a warm, dry location. If the unit has an integral battery,
recharge the unit prior to storage.

Acceptable storage temperature: -30ºC to +60ºC (-22ºF to +140ºF)

2-2

2.5 Signal Wiring

External input capabilities of the sampler are implemented by the use of an
optional external signal cable plugged into an external receptacle on the side of
the sampler. External inputs of different types can be used by choosing the
appropriate pair of wires in the cable.

On the PVS4150 the signal cable is combined with the AC Power cable, thus
limiting the number of connections possible.

FIGURE 2-2. External Signal Cable for PVS4100 and PVS4120

Section 2. Installation

IMPORTANT

Wiring to remote/external functions should AVOID ALL AC
POWER LINES if possible and/or be run in shielded cable
terminating the shield at the AC ground terminal at the remote
site.
