General information

2.2 Applications

ULTRATURB sc bypass sensors are innovative precision turbidity measuring
instruments developed using the latest technical findings.
ULTRATURB sc bypass sensos are developed primary for waste and drinking
water applications. The very robust seawater version is developed especially for
seawater applications with high salt concentrations (e.g. drinking water
abstraction from seawater, fish farming or seawater aquariums).
Turbidities in the range of FNU (NTU) 0.0001

–1000 are measured and displayed

alphanumerically using a controller. This high resolution facilitates precision
differentiation, even for ultra clear liquids.

A pulsed, long-life IR radiation source (LED) ensures that costs are minimised.

ULTRATURB sc turbidity sensors are designed in accordance with
DIN EN ISO 7027 and are permanently calibrated before leaving the factory. All
key data is set to practical standard values.

The instruments are immediately ready for use after connection to the power
supply and the supply of sample water. The measuring range and all data outputs
are modified to suit requirements using menus on the controller.

All optical and electronic assemblies are installed in housings that are physically
very strong and proof against water jets.

ULTRATURB sc turbidity sensors are available in the classic basic version, the
convenient plus version and the robust seawater version.

The measuring chambers of the ULTRATURB plus sc and of the
ULTRATURB seawater sc also have automatic wiper cleaning that reliably
prevents soiling of the optical systems as it starts to build up and significantly
reduces the user maintenance. Cleaning is performed at an interval set to suit
local requirements. The cleaning intervals are adjusted to suit the expected level
of soiling during commissioning. The user can straightforwardly change the
interval at a later date. The number of cleaning operations already performed can
be checked on the SENSOR SETUP menu using the COUNTER command.

2.3 Measuring principle

The nephelometric scattered light technique is a method for the determination of
the very low to medium turbidities in liquids that is comparable worldwide.

Using this method, the light scattered sideways by the turbidity particles is
measured over an angle of 90°. The low acquisition limit for this method makes it
possible to even reliably differentiate turbidity particles in distilled water. This
technique is defined in DIN EN ISO 7027. ULTRATURB sc sensors are designed
in accordance with the requirements in this standard.

2.4 Handling

The sensor contains high-quality optical and electronic assemblies. For this
reason attention is to be paid to ensuring that the sensor is not subjected to any
hard mechanical knocks. There are no components that can be maintained by the
user inside the sensor or the display unit – except the manual cleaning of the
measuring chamber and the replacement of the wiper profiles and the desiccant.

2.6 Function check

After unpacking, all components should be checked for any transport damage and
a short function check performed prior to installation.

For this purpose the sensor is connected to the display unit and the display unit
plugged into the mains. Shortly after the display unit is plugged in, the display is
activated and the instrument switches to the display of measurements. Here the
measured value taken in air is meaningless.

Note: It is only possible to check the operative zero point using very high purity water!

If no messages appear in the lower part of the display, the function check is then
complete.

Section 3 Installation

DANGER
Installation may only be carried out by qualified experts in accordance with
all local safety regulations.

3.1 Assembling

Select an appropriate installation location for the instrument to guarantee

• safe installation

• safe operation

• problem-free maintenance

Plan how to lay cables and hoses and their path in advance. Lay the hoses, data
cables and power cables without any bends. Only original replacement and
accessory parts recommended by the manufacturer may be used.

Make sure the mount has a sufficient bearing capacity. The dowels must be
selected and authorized according to the condition of the wall. The manufacturer
shall accept no liability if the instrument is installed incorrectly.

Install the instrument in a horizontal position.

Installation

3.1.1 Connectors

Important Note: The instrument can be damaged if the connectors and/or the
union nuts are attached too tightly. Only hand-tighten the union nuts for the hose
mounts. If necessary, hold the connectors with a tool (SW 22).

The measuring instrument can be integrated into the measurement and analysis
process using tubing (ID 13 mm) or a fixed connection (PVC system component
pipework, compatible with 1" union nut).

3.1.1.1 Selection of diaphragm plate

With samples that tend to emit gases, bubbles may form in the measuring
chamber. This causes extremely strongly fluctuating measurement values. In the
event of strongly fluctuating measurement values, replace the diaphragm plate in
the drain connector.

Note: Observe the flow quantity and flow direction of the sample provided in the technical
data.

Section 5 Maintenance

It has been possible to reduce the scope of the maintenance to be performed by
the user to only a few actions. Clearly summarised in a table and described in
detail in the following sections, these actions can be quickly and straightforwardly
performed by qualified personnel.

5.1 Maintenance schedule

5.2 Cleaning measuring chamber

The cleanliness of the measuring chamber is crucial for correct measured results.
This cylindrical optical measuring chamber has a rotating wiper with three wiper
profiles (only on plus and seawater version); these prevent normal soiling of the
optical system as it starts to build up. With very stubborn deposits, manual
cleaning with a suitable cleaning agent (e.g. citric acid) is recommended.

CAUTION
Observe safety regulations and wear safety clothing!

• Safety glasses

• Gloves

An automatic wipe is performed.

5.3 Replacing wiper profiles (only plus and seawater version)

The life of the wiper profiles is, on the one hand, dependent on the number of
cleaning actions performed, and on the other hand is also dependent on the type
of deposits to be removed. Thus the life of the wiper profiles varies from case to
case.

The wiper profiles supplied with the instrument are sufficient to the cover
requirements for an average year.

5.4 Replacing desiccant

The ULTRATURB sc turbidity sensor is continuously subject to a wet environment.
To provide protection against the moisture, there are 2 generously sized desiccant
bags close to the optical and electronic components. To maintain this protection,
the manufacturer recommends replacement or regeneration every 2 years.

To replace the desiccant, open the housing and replace the two desiccant bags,
4 units (see Figure 6, item 1) and 0.5 units (see Figure 6, item 2) as per the figure.

Maintenance

5.5 Monitoring test equipment

As part of a quality assurance system for test equipment monitoring, it is
necessary to check the instrument calibration; this can be performed using a
formazine standard series in accordance with DIN EN ISO 7027.

You can either make up the formazine solution yourself as per the instructions that
follow 5.5.1 Preparing formazine solution in accordance with DIN EN ISO 7027 or
procure it from the manufacturer (LCW 813 or Stabl Cal).

1. To check the instrument calibration, first thoroughly rinse out the measuring
chamber using distilled water.

2. Prepare a turbidity series using formazine reference solutions as per DIN EN
ISO 7027; the measuring series should correspond to the measuring range
selected. For example, in the measuring range FNU 0–5.0 chose reference
solutions with FNU 0.5–1.0–2.0–3.0–4.0.

Note: If there are any variations in the measurements, it is recommendable to measure a
new standard preparation prior to changing the instrument calibration! Experience has
shown that the variation in the formazine preparation can be greater than the possible drift
in the ULTRATURB instrument.

When checking the instruments as per EN 450901 or GLP we therefore
recommend recording the date in an instrument log and checking for any long­term drift. Checks on the operation of the ULTRATURB can in practice also be
made by means of parallel measurements with turbidity photometers designed in
accordance with DIN and ISO.

5.5.1 Preparing formazine solution in accordance with DIN EN ISO 7027

Chemicals

Chemicals of "analysis" purity are used. The chemicals must be stored in hard
glass bottles.

Water

• Place a membrane filter, pore size 0.1 µm (for bacteriological

experiments), for 1 hour in 100 mL of distilled water.

• Filter 250 mL water through this filter and discard the water.

• Then filter 500 mL of distilled water twice through the same filter and use

this water for making up the standard solution.

Formazine (C

2H4N2

) parent solution

CAUTION
Hydrazine sulphate is toxic and possibly carcinogenic

• Dissolve 10.0 g of hexamethylentetramine (C

6H12N4

) in water and top up

to 100 mL (solution A).

• Dissolve 1 g of hydrazine sulphate (N

2H6SO4

) in water and top up to

100 mL (solution B).

• Mix 5 mL of solution A with 5 mL of solution B.

• After 24 hours at 25° C (±3 °C) (77 °F (± 5.4 °F)) top up this solution with

water to 100 mL.

Maintenance

25

The turbidity of this parent solution is 400, stated in Formazine Attenuation Units
(FAU) or Formazine Nephelometric Units (FNU). This solution can be stored in a
dark place at 25 °C (±3 °C) (77 °F (± 5.4 °F)) for around 4 weeks.

Formazine reference solution

Dilute the parent solution with the aid of pipettes and measuring flasks to produce
reference solutions in the required range. These solutions can only be stored for a
very limited period.
