3.2 Incoming acceptance, transport, storage
• Make sure the packaging is undamaged!
Inform the supplier about damage to the packaging. Keep the damaged packaging until the matter
has been settled.
• Make sure the contents are undamaged!
Inform the supplier about damage to the delivery contents. Keep the damaged products until the
matter has been settled.
• Check that the scope of delivery is complete and agrees with your order and the shipping
documents.
• The packaging material used to store or to transport the product must provide shock protection
and humidity protection. The original packaging offers the best protection. Also, keep to the
approved ambient conditions (see "Technical data").
• If you have any questions, please contact your supplier or your sales center responsible.
3.3 Installation conditions
3.3.1 Notes on installation
Installation positions
The sensor has to be immersed completely into the media. Avoid bubbles in the area of the sensor.
!Note!
For use in hygienic applications only use materials that comply with 3-A standards 74-03 and the
FDA requirements. The cleanability of a sensor also depends on the way of installation. To install
the sensor in a pipe system use the appropriate and EHEDG certified flow assembly for the
respective process connection.
a0005442
Fig. 3: Installation positions of conductivity sensors
A Not for hygienic applications
Air set
Perform an air set before sensor installation (see chapter "Calibration"). Make sure that the
instrument is ready for operation, i.e. mains and sensor are connected.

Wall distance
The sensor’s distance from the pipe wall affects the measuring accuracy (see Fig. 5).
a0005441
Fig. 5: Relationship between installation factor and distance from wall a
1 Electrically conductive pipe wall
2 Insulating pipe wall
In narrow installation conditions, the ion flow
in the medium is affected by the pipe walls.
This effect is compensated by the so-called
installation factor.
When the distance from the wall is sufficient,
i.e. a > 15 mm / 0.59", the installation factor
can be ignored (f = 1.00). When the wall
distance is lower, the installation factor
increases in the case of electrically insulating
pipes (f > 1) while it decreases for electrically
conductive pipes (f < 1); see Fig. 5.
The determination of the installation factor is
described in the chapter "Calibration".
