4.1 Installation conditions
4.1.1 Orientation
The sensor must be completely immersed in the medium. Avoid air bubbles in the area of the
sensor.

Installation Indumax CLS54
12 Endress+Hauser
> 1 m (3.3 ft)
A0017691
 1 Installation positions of the conductivity sensor
If the flow direction changes (after pipe bends), turbulence in the medium can result.
Install the sensor at a distance of at least 1 m (3.3 ft) downstream from a pipe bend.
The product should flow along the hole of the sensor (see the arrows on the housing). The
symmetrical measuring channel allows flow in both directions.
For a 3-A compliant installation, the following must be noted:
After the instrument is installed its hygienic integrity shall be maintained. All process
connections must be 3-A compliant.

Indumax CLS54 Installation

4.1.2 Installation factor
The ionic current in the liquid is affected by the walls in
confined installation conditions. This effect is compensated
by what is referred to as the installation factor. The
installation factor can be entered in the transmitter for the
measurement or the cell constant is corrected by multiplying
by the installation factor.
The value of the installation factor depends on the diameter
and the conductivity of the pipe nozzle as well as the
distance a between the sensor and the wall.
The installation factor f (f = 1.00) can be disregarded if the
distance to the wall is sufficient (a > 15 mm, from DN 65).
If the distance to the wall is smaller, the installation factor
increases for electrically insulating pipes (f > 1), and
decreases for electrically conductive pipes (f < 1).
It can be measured using calibration solutions, or a close
approximation can be determined from the diagram below.

6 Maintenance
LCAUTION
Corrosive chemicals
Danger of chemical burns to the eyes and skin. Danger of damage to clothing and equipment
‣It is absolutely essential to protect the eyes and hands properly when working with acids,
bases and organic solvents!
‣Wear protective goggles and safety gloves.
‣Clean away splashes on clothes and other objects to prevent any damage.
‣Pay particular attention to the information provided in the safety data sheets for the
chemicals used.
As there is no galvanic contact with the medium, inductive sensors are considerably less
sensitive to dirt and fouling than conventional conductive sensors.
However, dirt can clog the measuring channel which, in turn, can alter the cell constant. In
such cases, an inductive sensor also needs to be cleaned.
Clean away fouling on the sensor as follows depending on the type of fouling:
• Oily and greasy films:
Clean with grease remover, e.g. alcohol, acetone, possibly hot water and dishwashing
detergent.
• Lime and metal hydroxide buildup:
Dissolve buildup with diluted hydrochloric acid (3 %) and then rinse thoroughly with plenty
of clear water.
• Sulfidic buildup (from flue gas desulfurization or sewage treatment plants):
Use a mixture of hydrochloric acid (3 %) and thiocarbamide (commercially available) and
then rinse thoroughly with plenty of clear water.
• Buildup containing proteins (e.g. food industry):
Use a mixture of hydrochloric acid (0.5 %) and pepsin (commercially available) and then
rinse thoroughly with plenty of clear water.
