Introduction
The Lovibond®PTV Series Turbidimeters are continuous-reading process monitoring
instruments for filter management and regulatory reporting for turbidity in potable
water. This includes regulatory reporting of turbidity for the United States Environmental
Protection Agency (USEPA) or ISO 7027 International Standard. The Lovibond®PTV Series
Turbidimeters may be applicable for water monitoring application in which the expected
turbidity is typically less than 10 NTU or FNU.*The Lovibond PTV Series Turbidimeters
are designed to detect an incremental change in turbidity of less than 0.0005 NTU when
measuring below 0.05 NTU. This sensitivity is 100 times lower than the sensitivity as
specified by USEPA 180.1 (measurement rounding).
1. Measurement Module (synonymous to turbidimeter 'Head') - The Measurement
Module of the turbidimeter contains the light source, optics, signal processing, data
storage, display and a touch screen user interface. The local touch screen permits
operation of the Lovibond® PTV Series Turbidimeters without an external controller. The
'Home' screen displays the current turbidity value and status of the turbidimeter.
2. Flow Body - The Flow Body contains the components that come in contact with the
sample and is engineered to ensure consistent results over a large range of operating
conditions. The flow body incorporates design elements necessary for low-level turbidity
detection. Routine maintenance, such as calibration and cleaning, can be performed
without the use of tools and with low chemical exposure.
3. Power & Communications Module (PCM) - The PCM contains the high voltage power
supply, digital and analog communication interfaces. (A complete description of PCM
including all electrical installation instructions are included within a separate manual. A
qualified electrician trained in the installation of electrical equipment should read and
understand prior to working with this component as potential lethal hazards are present).
Product Overview
*For the purposes of specification, FNU = NTU when
1) The instruments are calibrated on Formazin based standards and
2) Formazin is used in the derivation of the specifications. It is possible for FNU and NTU to differ on real world samples.

Introduction
Product Overview
PTV 6000 ONLY The PTV 6000 Process Turbidimeter is a Class 1 Laser product that
includes an interlocked, non-serviceable, Class 3B laser. Two interlocks ensure the user is
not exposed to laser radiation.
1. Measurement Module Interlock - The internal interlock disables the beam when the
Measurement Module is removed from the flow body, or when the flow body is removed
from the Mounting Cleat.
2. Bubble Trap Cover Interlock - The external interlock disables the beam when the
bubble trap cover is removed.
Note: PTV 1000/2000 bubble trap cover will not enable the laser.
Use only 19806-048 cover with the PTV 6000.
The PTV 6000 must be returned to the factory for service.
DANGER
PTV 6000: Class 3B laser radiation when open and interlocks defeated,
avoid exposure to the beam.

Introduction
Laser turbidimeters such as the PTV 6000 possess highly improved optical qualities to yield
a very stable process measurement system. This enhanced stability provides additional
information that can be deciphered from the laser turbidity measurement itself and
used as a separate parameter to further improve the limit of detection to breakthroughs
in filtration systems. This parameter is known as the RSD parameter. The parameter
has been shown to also enhance the sensitivity of detection of minor breakthroughs in
different filtration systems. Studies in conventional anthracite filtration, micro-filtration,
ultra-filtration, Nano-filtration, and reverse-osmosis filtration have proven out this process
detection parameter. 1
Using the RSD parameter as a predictive indicator of a pending filtration breakthrough
requires an optical arrangement wherein the measured portion of the sample, (or view
volume), is interrogated by a beam of light of high energy density, preferably a laser. An
incident beam of high energy density is capable of detecting the presence of particles in
very low concentrations. A conventional turbidimeter without the use of a high-density
beam is capable of detecting particles of approximately 1.0-µm or larger, whereas a laser
turbidimeter is capable detecting particles as small as 0.01-µm. This enables the laser
turbidimeter to detect very small breaches in a filter such as a pinhole.
Laser turbidimeters are designed to meet these criteria and, like particle counters, can
use the real time derivative of their monitoring baselines as an independent indicator
of a membrane breach. One commercially available laser turbidimeter that offers RSD
parameter is the PTV 6000. This parameter is automatically viewed on the instrument’s
touchscreen and has the unit “RSD” and on those mobile devices that are connected to
the respective PTV 6000.
Use of this parameter should be based on each water treatment plants design and
operational parameters. A general guideline is that RSD values that are less than 1 percent
indicate stable filtration operation. Values exceeding 1 percent can indicate particle
leakage through a filtration system.

Installation
General Guidelines
Before beginning the installation, locate an area with a solid wall to mount the instrument
that is away from heavy traffic, exposure to direct sunlight or other heat sources, with
minimum dust and vibration. The panel mount option is recommended to ensure proper
installation, to manage cables and to provide conveniences that help increase work flow
efficiency.
WARNING
There are multiple hazards associated with the installation of this equipment.
Installation of this equipment should only be conducted by qualified personnel.

Installation
Installing the Mounting Plate
Allow 25-cm (9.8 inch) above and 6-cm (2.4 inch) clearance to the right of the mounting
plate for serviceability and cable routing. The mounting plate attaches to the vertical wall
using four M6 or 1/4 inch stainless steel bolts, (of a suitable style and length determined
by installer, to assure the mounting plate is securely attached).
NOTICE
Do not over-tighten screws and deform the mounting plate during installation.
Mechanical Installation
• Install this instrument on a wall.
NOTICE
ALLOW AN ADDITIONAL 30.5CM (12" INCH) CLEARANCE FROM THE TOP OF THE
FLOW BODY FOR REMOVAL OF THE MEASUREMENT MODULE.

GB
Installation
Fluidic Connections
ASTM D6698 sampling conditions should be followed for this installation.
Sample tap (from the source)
Sample tap should project into the center of the pipe to minimize interference from air
bubbles or sediment. Sample lines should be as short as possible to minimize reading
delays due to changes in the sample turbidity. Avoid sample line routings which cause the
inlet pressure to drop below the recommended sample line pressure minimum; (this can
cause air lock conditions within the sample line).
Sample Line Installation
1. Adjust the length of the ¼-inch (6mm) sample tubing to minimize the distance that
the sample must travel.
2. Cut the ¼-inch (6mm) sample tubing square to ensure a secure and leak free
connection.
3. Insert the sample line into the shutoff valve inlet located on the bottom of the PTV
series Flow Body; push firmly to seat the tubing in the shutoff valve
Drain Line Installation
1. Connect a 3/8-inch (9mm) ID tube to the 3/8-inch (9mm) barbed fitting located on
the bottom of the PTV series Flow Body and route to drain.
NOTICE
For setup and/or for real time 'at-the-head' observations, a 0 to 100 ml/min rotameter
may be installed into the 1/4-inch sample flow line as a visual flow indicator.
See Accessories & Replacement Parts section for details.
NOTICE
Avoid drain line routings which can become kinked or trap water within the drain tubing
when no grab sample air break is present at the turbidimeter Outlet Fitting.
