5.1 Installation conditions
5.1.1 Installation instructions
For a 3-A compliant installation, the following must be noted:
After the instrument is installed its hygienic integrity shall be maintained. The
instrument shall be installed with the leakage detection at the lowest point of the
assembly. Furthermore all process connections must be 3-A compliant.
Orientations
The sensor must be completely immersed in the medium. Avoid air bubbles in the area of the
sensor.
> 1 m (3.3 ft)
A0017691
 2 Orientation of conductivity sensors
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.

Installation Smartec CLD18
12 Endress+Hauser
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.
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 can be disregarded (f = 1.00) if the
distance to the wall is sufficient (a > 20 mm, from DN 60).
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 following diagram.

5.2 Mounting the compact device
Choose the installation depth of the sensor in the medium such that the coil body is
completely immersed in the medium.
Pay attention to the information on wall clearance in the "Installation conditions" section.
Mount the compact device directly on a pipe nozzle or tank nozzle via the process connection.
For the 1½" threaded connection, use a Teflon tape to seal the connection and an adjustable
pin wrench DIN 1810, flat face, size 45 to 50 mm, to tighten it.
1. When installing, align the compact device in such a way that the medium flows through
the flow opening of the sensor in the direction of medium flow. Use the arrow on the
nameplate to help you align the device.
2. Tighten the flange.
5.3 Post-installation check
• After installation, check the compact device for damage.
• Ensure that the compact device is protected against direct sunlight.
