TurbiTechw² LR Instruction Manual
1 Foreword
The TurbiTechw² amily o sensors are the latest version o the TurbiTech range. The 'w²' in the product title
denotes compatibility with the Waterwatch² range. The sensors are designed or use with the 7300w²
Monitor. The term TurbiTech is used or any Partech sel -cleaning, Suspended Solids or Turbidity Sensor.
The TurbiTechw² LR Sensor has been speci ically designed to monitor inal treated, potable and ilter water.
The sensor is extremely sensitive and is capable o discriminating changes in Turbidity o less than 0.1 NTU.
The 90° light scatter monitoring technique makes the sensor sensitive to a wide range o particle sizes, rom
colloidal material through to larger particles and raw waters and the large mineral particles sometimes ound
in distribution samples.
The sensor requires very little maintenance, with no special tools or training required. Calibration can be
carried out against either a wet Turbidity standard or using the dry calibration re erence cell that is supplied
with every sensor. The re erence cell provides an extremely easy, repeatable method o checking the
per ormance o the sensor without the cost and inherent errors associated with chemical standards.
The TurbiTechw² LR Sensor complies with the internationally recognised ISO7027 standard or Turbidity
measurement. The unique sensor design captures stray light which ensures an ultra stable zero point, this is
combined with an automatic sel -cleaning mechanism that prevent the build up o ouling within the sample
chamber.

4 The ensor and Installation
Whilst every attempt has been made to ensure that these instructions are correct, common sense and good
engineering practice should always be used, as every installation can present a new set o challenges and
di iculties. I you are in any doubt please contact Partech or your local distributor or urther in ormation.
4.1 TurbiTechw² LR ensor
All the TurbiTechw² Sensors in the amily use an LED in ra red light source, which o ers long-term
stability, low maintenance and high reliability. All TurbiTechw² Sensors use either Light Scatter or Light
Absorption to per orm their measurement.
In simple terms, turbidity means cloudy, hazy or not pure. All drinking water, both raw and treated
contains some degree o turbidity due to dispersed suspended particles such as silt, clay, algae,
organic/inorganic matter or micro organisms.
Turbidity is a measurement quanti ying the degree to which light travelling through the water sample is
scattered by the suspended particles. The transmission o light is determined by physical parameters
such as particle concentration, size, shape and chemical properties. The scattering o light increases
with a greater concentration o suspended load. Turbidity is commonly measured in Nephelometric
Turbidity Units (NTU). The nephelometric method compares the light scattered by the sample and the
light scattered by a re erence solution.
The TurbiTechw² LR Sensor measures the turbidity o the sample water in NTU's in accordance with
established measurement techniques. The measurement cell has been designed to reduce unwanted
stray light to an absolute minimum resulting in a very accurate zero point. The 7300w² Monitor has the
acility or converting the units to mg/l under some circumstances, urther details are provided in the
7300w² Monitor user manual.
The beam rom the LED light source is passed through the sample o water contained in the measurement
cell and the amount o light scattered by particles in the sample is measured at 90 degrees to the light
source. The 7300w² Monitor uses an LED light source with an optical eedback loop to maintain constant
light levels. The sample lows through the lowcell continuously while the TurbiTechw² LR Sensor is in
measurement mode. The large bore lowcell reduces the danger o ouling or clogging in raw water
applications.
The TurbiTechw² LR sensor is a dedicated lowcell sensor and uses a wiper type cleaner. In the
intended clean water applications this wiper is more than capable o keeping the optical sur aces
clean. The wiper should be replaced every two years to ensure the cleaning unction remains e ective.
The TurbiTechw² LR sensor is available in two ranges; 0 to 30NTU & 0 to 500NTU. The range is
dictated by the hardware o the lowcell so cannot be changed by the user. There ore the range should
be speci ied when the instrument is ordered.
All the example screens in this manual relate to the 0 to 30NTU sensor. All the menu options and
unctionality are identical between the ranges except or the actual numeric value and number o
decimal places o NTUs.

TurbiTechw² LR Instruction Manual
5 Mechanical Installation
5.1 Operation Limits
5.1.1 Temperature
The upper operational temperature limit is restricted to 60°C. At low temperatures the limit o operation
is 0°C with the practical limitation being ice ormation in the sample. The construction o the sensor is
such that condensation should not present a problem.
5.1.2 Pressure
The standard lowcell provided is not intended or high-pressure applications and should not be
subjected to internal pressures in excess o 1 Bar.
5.1.3 Maximum Levels
High turbidity levels can cause ouling problems that will require manual intervention. An inherent
eature o the principal o operation o the TurbiTechw² Sensor is that at very high turbidity levels the
sensor output will be seen to reduce, this can in some circumstances produce alse low readings.
5.1.4 Material Compatibility
Care should also be taken to ensure material compatibility between the media being monitored and
the wetted parts o the assembly. The principle wetted parts are black Acetal Co-Polymer,
Polypropylene, with Glass Lens. I you are in any doubt about chemical compatibility please contact
Partech.
Regulations governing the use o equipment in contact with potable water exist and these need to be
understood by the user o this product. It is Partech's belie that the low sur ace area in contact with
the potable water and the normal installation practise o eeding the sample stream to waste mean that
this product is suitable or use in potable water treatment processing.
5.2 ensor Components
The TurbiTechw² Sensor comprises o the transmitting module (light source), receive optics, cleaning
mechanism, drain valve, and inter ace unit.
225769IM - Issue - 05 Issue Date 30/0 /2019 Page 11 of 3

TurbiTechw² LR Instruction Manual
5.2.1 Transmitter Module
The transmit module, positioned to the right o the low cell, contains the solid-state emitter and the
light intensity control components. The light intensity is controlled automatically preventing signal
degradation with time. The light beam passes through the sample water. Light is scattered and
ocused onto the target area. The transmitter contains precision optical components and must be
handled with care.
There is an O-ring seal on the ace o the transmitter module. The light source module is retained
using a screw collar.
5.2.2 Receiver Module
The receive module itted on the ront o the low cell is sealed and needs no routine service. The
module contains a photo-diode that receives the light rom the solid-state light source. The output rom
the receiver module passes to the microprocessor. The received signal is increased proportionally with
the turbidity level.
The receiver uses a combination o optical gain and electronic gain to view a very small area o the
low cell. The receiver contains precision optical components and must be handled with care.
The receiver module may be removed rom the low cell by removing the cable rom the inter ace and
the rubber grommets on the bracket. The module can then be unscrewed rom the housing. There is
an O-ring seal on the ace o the receiver module.
5.2.3 Cleaning Module
The cleaning module is located in the top o the measuring cell and locates with a screwed collar.
Access to the cell or manual cleaning is most readily obtained by removing the cleaning motor
assembly. The cleaning arm has a simple wiper blade attached to it. The module is controlled by the
7300w² Monitor. A location peg makes sure the module is correctly aligned during replacement.
Remove this cleaning module or access to the low cell or cleaning and calibration. Ensure the O-ring
is still in place at the bottom o the cleaning module when replacing back into the low cell.
5.3 Mounting & Installation
Whilst the TurbiTechw² Sensor is suitable or outdoor location we recommend that the 7300w² Monitor
is installed indoors or within an outer enclosure. Mount in a location ree rom excessive vibration.
5.3.1 Process Connections
Sample Inlet
½” BSP Female thread itted with 12mm Hose-tail, material Polyamide. The inlet is itted with a Nickel
plated brass ball valve.
Outlet
¼” BSP Female thread itted with 8mm Hose-tail, material Polyamide. This should be ree lowing to air
and not impose any siphoning e ect on the system. The smaller outlet will naturally create a small
positive pressure within the low cell and help minimise the e ect o micro-bubbles on the reading.
Manual Drain
There is a manually operated drain tap at the bottom o the low cell. This allows the cell to be emptied
prior to cleaning or calibration. Isolate the sample low be ore draining the cell.
½” BSP Female with 12mm Hose-tail itted, material Polyamide. The manual drain is itted with a
Nickel plated brass ball valve.
5.3.2 ample Flow Rate
The sample low rate should ideally be in the region o 1 litre/minute. The minimum recommended low
rate is 0.5 l/min, a lower low rate will not cause any damage but will result in a slow system response
Page 12 of 3 225769IM - Issue - 05 Issue Date 30/0 /2019

TurbiTechw² LR Instruction Manual
time. The maximum low rate is 5 l/min, low rates higher than this can cause problems with pressure
and turbulence.
5.3.3 ample Pressure
The sensor is not intended as a pressure containing vessel, however a small positive pressure across
the cell is desirable or maintaining a smooth low and to keep gases dissolved in solution. The
maximum operating pressure is 1 Bar.
5.4 Optional Accessories
Bubbles in the sample will cause alse high and/or unstable readings, micro-bubbles can be generated
i the sample pressure is reduced prior to passing through the lowcell. A De-Bubbler is available, but
will generally not improve situations where micro-bubbles are problematic. For evening out erratic low,
including occasional air intrusions, the De-Bubbler is an ideal solution. Please talk to Partech about
options or mitigating sample conditioning issues.
Note, when itting the De-Bubbler, please ensure the outlet is positioned minimum 300mm higher than
the inlet to the low cell. This will ensure the lowcell has a minimum o 300mm head o pressure.
Adjust the low through the De-Bubbler “Sample Inlet” high enough to allow a low out o the De-
Bubbler vent. Once a low is established, allow to settle or a ew minutes, then reduce the low until
the Vent low just stops (a small dribble rom the vent is pre erable to allow or small luctuations in the
low). The De-Bubbler is now correctly set.
5.4.1 Optional Flow Verification Detector
The low veri ication detector is an optional extra or the measuring system. The low veri ication
detector is itted in-line with the over low drain outlet. Once connected to the system, the low
veri ication detector will provide a signal when no low is detected.

6.1.2 ensor Connections
When routing the sensor cables, please ensure the cable is separated rom any mains cables. Although the
Partech w² sensors have a high resistance to inter erence, separation o mains and data cables is good
practice and should always be ollowed where practical.
All sensors in the w² range communicate with the monitor using the ModTechw² Protocol. This protocol has
been speci ically designed to take advantage o the advanced eatures and diagnostics designed into the w²
range o sensors.
Note- These sensors can NOT be used with other monitors that are not included in the w² amily.
All sensors within the w² amily o instruments are connected to the 7300w² Monitor using the same 4 wire
con iguration.
•RED and BLACK wires provide the 12VDC supply to the sensor.
•WHITE and GREEN provide data communication.
A maximum o two sensors can be directly connected to the standard 7300w² Monitor, additional sensors
can be added using the optional expansion boxes available separately.
Remove the 4-way connector rom the 7300w² Monitor by pulling downwards to disconnect or easy access
to the connections. Connect the sensor cores as ollows-
(Terminals rom le t to right on the 4 way connector)
Term 1 (Le t) - RED (+12V)

6.1.3 Extending ensor Cables
Sensors are usually supplied with 10M cables (longer cables can be provided i requested). These cables
can be extended to a maximum length o 100M. To ensure optimum per ormance, only use Partech
ModTechw² cable or extensions. Partech can supply junction boxes to allow or cable extensions. These
should be used on all installations where the cable length rom the sensor to the monitor exceeds 20M
(Partech Junction boxes include on-board iltering or long cable lengths). Junction boxes are also use ul or
local connection o sensors close to the sample point. This allows or easy replacement o sensors without
the need to pull back cables to the monitor. The junction box has an on-board terminator switch that can be
activated to terminate the network i the sensor is to be removed or long periods.
When joining cables, ensure the connection is ully waterproo . Any moisture ingress can e ect the
communication between the sensor and monitor.
