    Waterwatch² range. The sensors are designed for use with the 7300w² Monitor. The term TurbiTech is used for any Partech self-cleaning, Suspended Solids or Turbidity Sensor. The TurbiTechw² LR Sensor has been specifically designed to monitor final treated, potable and filter water.

  • Page 7: Introduction

    Training in the use of the 7300w² Monitor and sensors can be provided, please contact Partech for further information. Icons have been used throughout this manual to draw your attention to precautions and useful notes.

  • Page 8: Safety Precautions

    Maintenance instructions for the TurbiTechw² sensor should be carried out as specified in this instruction manual. Failure to carry out regular maintenance could invalidate the Warranty. Services and repairs must be carried out by a Partech engineer. Partech can provide a service contract for your system. Please ask for details.

  • Page 9: End Of Life Disposal

    Any calibration solutions should be disposed of as described in the Manufacture Safety Data Sheet accompanied with the calibration solution. Partech can provide recycling and disposal of your old Partech equipment, and may also provide the same service for other manufactures equipment when replaced with Partech equipment.

  • Page 10: The Sensor 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 of challenges and difficulties. If you are in any doubt please contact Partech or your local distributor for further information. TurbiTechw² LR Sensor All the TurbiTechw²...

  • Page 11: Mechanical Installation

    Regulations governing the use of equipment in contact with potable water exist and these need to be understood by the user of this product. It is Partech's belief that the low surface area in contact with the potable water and the normal installation practise of feeding the sample stream to waste mean that this product is suitable for use in potable water treatment processing.

  • Page 12: Transmitter Module

    TurbiTechw² LR Instruction Manual 5.2.1 Transmitter Module The transmit module, positioned to the right of the flow 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 focused onto the target area.

    A De-Bubbler is available, but will generally not improve situations where micro-bubbles are problematic. For evening out erratic flow, including occasional air intrusions, the De-Bubbler is an ideal solution. Please talk to Partech about options for mitigating sample conditioning issues.

  • Page 14: Electrical Installation

    When routing the sensor cables, please ensure the cable is separated from any mains cables. Although the Partech w² sensors have a high resistance to interference, separation of mains and data cables is good practice and should always be followed where practical.

  • Page 15: Extending Sensor Cables

    Sensors are usually supplied with 10M cables (longer cables can be provided if requested). These cables can be extended to a maximum length of 100M. To ensure optimum performance, only use Partech ModTechw² cable for extensions. Partech can supply junction boxes to allow for cable extensions. These should be used on all installations where the cable length from the sensor to the monitor exceeds 20M (Partech Junction boxes include on-board filtering for long cable lengths).

    TurbiTechw² LR Instruction Manual 8 Measurement Configuration The monitor leaves the factory without any measurements configured. Measurements can only be added after installing the relevant sensor(s). Once the sensor(s) have been registered with the monitor and installed, the measurements will now be available.

  • Page 21: Calibration

    The most accurate method of calibration is using a primary standard, i.e. formazine solution. This procedure has associated health risks, therefore Partech supply a dry secondary standard with each flowcell. These standards have been given a calibrated value that is equivalent to formazine in NTU. Under normal circumstances and the correct storage these standards will last the life time of the instrument.

Calibration Zero To calibrate the sensor, switch off the inlet hose and remove the cleaning module. The cleaning module is located in the top of the measuring cell and locates with a screwed collar. A location peg makes sure the module is correctly aligned during replacement.

  • Page 24: Take Sample

    TurbiTechw² LR Instruction Manual 9.5.1 Take Sample The TurbiTechw² sensor should filled with an instance of the desired sample representative of the normal operating conditions expected from the sample point. The cleaning motor must be present to exclude light. Allow the reading to stabilise before entering the Take Sample’ routine. Care is needed to ensure that air bubbles are not causing a calibration error.
