For the safety of our employees and because of legal regulations we need a
signed “declaration of decontamination” before your return can be handled.
This signed declaration must be included with the shipping documents on the
outside of the packaging.
Any returns which were exposed to hazardous substances and were not
professionally decontaminated are not accepted and will be sent back on your
cost.
optek’s declaration of decontamination and contact information can be found on
our website www.optek.com.
2.2 Disposal
Special legal regulations apply to the return and disposal of industrial waste
equipment. However, manufacturer and user can contractually agree on which
party is to fulfill these legal obligations.
Observe current national disposal regulations.
To dispose packaging material, please separate materials into the following
groups:
• Paper / paperboard
• Plastic
For disposal, disassemble the system components and separate them
according to different material groups.
Dispose of materials according to national and local regulations.
If no agreement has been made, products may be shipped to optek for disposal.

3 Intended use
The optek-sensors TF16 and their variants are to be applied only as scattered
light turbidimeters for liquids and gases in inline applications according to the
technical data.
The use of the sensors in hazardous locations is prohibited.
You can purchase flameproof sensors for hazardous locations from optek. For
these sensors, special instruction manuals are delivered with the sensor.
Unauthorized constructional changes, additional fittings or rebuildings regarding
the sensor are prohibited. The only exception are rebuildings into one of the va-
riants listed in the chapter "Validity of the instruction manual". Changes to and
interference with the converter program are prohibited as well.
To lay sensor cables underground without protection is prohibited.
The manufacturer is not liable for damage resulting from misuse.
Following this instruction manual is part of the intended use.

4 Description of TF16 / TF16-N sensors
The TF16 model is a high precision dual channel scattered light turbidimeter. It
measures direct light and light scatterd from particles in the process medium at
an angle of 11°. The sensor is made entirely of stainless steel and designed for
direct installation into pipelines.
Fig. 1 TF16
The following are the main sensor components:

1. Sensor body
2. Windows
3. Optics module
4. Detector (direct light)
5. Detector (scattered light)
6. Optics module
7. Lamp
Its modular construction offers maximum flexibility in adapting to the process,
without affecting the property of measurement. An appropriately defined light
beam penetrates the process medium. The light scattered from particles in the
process medium, e. g. traces of suspended solids, immiscible liquids or gas
bubbles, is detected by eight hermetically sealed silicon photodiodes at an angle
of 11°. Simultaneously, the unscattered light is detected as direct light by
another photodiode. The receiver optics design guarantees that extraneous
lights created inside the sensor body are not included in measurements.

Due to the small scattering angle, direct light and scattered light practically travel
the same distance in the process medium. This is why product specific
disturbances such as color or color changes of the carrier medium as well as
soilings on windows may be optimally compensated.
