PTV_Series_V2.2 01.2019

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.

PTV_Series_V2.2 01.2019

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.
