2 Orientation of conductivity sensors. Engineering unit: m (ft)
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.
In confined installation conditions, the walls affect the ionic
current in the liquid. This effect is offset 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.

8.4.1 Installation factor
In confined installation conditions, the conductivity measurement in the liquid is affected by
the pipe walls. This effect is offset by the installation factor. 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 sensor's distance to the wall.
The installation factor f (f = 1.00) can be disregarded if the distance to the wall is sufficient
(a>20 mm (0.79 in), from DN60).
If the distance to the wall is small, 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 determined from the
following diagram.

8.4.2 Temperature compensation
The conductivity of a liquid depends heavily on the temperature, as the mobility of the ions
and the number of dissociated molecules are temperature-dependent. In order to compare
measured values, they must be referenced to a defined temperature. The reference
temperature is 25 °C (77 °F).
The temperature is always specified when the conductivity is specified. k(T0) represents the
conductivity measured at 25 °C (77 °F) or referenced back to 25 °C (77 °F).
The temperature coefficient α represents the percentage change in the conductivity per degree
of temperature change. The conductivity k at the process temperature is calculated as follows:
A0009163
Where
k(T) = conductivity at process temperature T
k(T0) = conductivity at process temperature T
0
The temperature coefficient depends on both the chemical composition of the solution and on
the temperature, and is between 1 and 5 % per °C. The electrical conductivity of the majority
of diluted saline solutions and natural waters changes in a close-to-linear fashion.
Typical values for the temperature coefficient α:
Natural waters
Approx. 2 %/K
Salts (e.g. NaCl) Approx. 2.1 %/K
Alkali (e.g. NaOH) Approx. 1.9 %/K
Acids (e.g. HNO3) Approx. 1.3 %/K

8.4.3 Measuring range switch (MRS)
Measuring range switching involves a parameter set changeover for two substances:
• in order to cover a large measuring range
• in order to adjust temperature compensation in the event of a product change
The two analog outputs can each be configured with two parameter sets.
• Parameter set 1:
• The parameters for the current outputs and the damping can be set Setup in the menu.
• The alpha coefficient for temperature compensation can be set Setup/Extended setup/
Input in the menu.
• Parameter set 1 is active if the "MRS" binary input is Low .
• Parameter set 2:
• The parameters for the current outputs, the damping and the alpha coefficient for
temperature compensation can be configured Setup/Extended setup/Remote switch in
the menu.
• Parameter set 2 is active if the "MRS" binary input High is .
The settings for parameter set 1 are also listed in Extended setup/Analog output the
menu.

8.5 Calibration (Calibration menu)
In the case of the Smartec CLD 18, the air set and the correct cell constant have already been
configured at the factory. A sensor calibration is not necessary during commissioning.
8.5.1 Types of calibration
The following types of calibration are possible:
• Cell constant with calibration solution
• Air set (residual coupling)
8.5.2 Cell constant
General
The calibration of a conductivity measuring system is always performed in such a way that the
suitable calibration solutions determine or verify the exact cell constant. This process is
described in the standards EN 7888 and ASTM D 1125, for example, and the method for
producing a number of calibration solutions is explained.

Calibrating the cell constant
With this type of calibration, enter a reference value for the conductivity.
‣
In the result, the device calculates a new cell constant for the sensor.
First switch off the temperature compensation:
1. Select the menu Setup/Extended setup/Input/Temp. comp. .
2. Off Select .
3. Return to the menu Setup .
Perform the calculation of the cell constant as follows:
1. Select the menu Calibration/Cell const. .
2. Cond. ref. Select and enter the value of the standard solution.
3. Place the sensor in the medium.
4. Start the calibration.
"Wait calib." - wait for calibration to end. The new value is displayed after the
calibration.
5. Press the Plus key.
"Save calib data?"
6. Yes Select .
"Calib successful"
7. Switch the temperature compensation back on.

Smartec CLD18 Commissioning
8.5.3 Air set (residual coupling)
For physical reasons, the calibration line goes through zero in the case of conductive sensors
(a current flow of 0 corresponds to a conductivity of 0). When working with inductive sensors,
the residual coupling between the primary coil (transmitter coil) and secondary coil (receiver
coil) must be taken into account or compensated for. The residual coupling is not only caused
by the direct magnetic coupling of the coils but also by crosstalk in the supply cables.
As is the case with the sensors, the cell constant is then determined using a precise calibration
solution.
To perform an airset, the sensor must be dry.
Perform an airset as follows:
1. Calibration/Airset Select .
The current value is displayed.
2. Press the Plus key.
"Keep sensor in air"
3. Keep the dried sensor in air and press the Plus key.
"Wait calib." - wait for calibration to end. The new value is displayed after the
calibration.
4. Press the Plus key.
"Save calib data?"
5. Yes Select .
"Calib successful"
6. Press the Plus key.
The device switches back to the measuring mode.
