2.1.Description of the System
This manual describes the function of the instruments:
AMI Powercon specific
AMI Powercon acid
Both instruments are applicable for the measurement of conductivity in power cycles.
The AMI Powercon specific measures the specific (total) conductivity of a sample.
The AMI Powercon acid measures the acid (cation) conductivity of
a sample. It is therefore delivered with a cation exchanger bottle.
The transmitter can be used with a two-electrode conductivity sensor with an integrated Pt1000 temperature sensor, e.g. Swansensor UP-Con1000.
Application

The conductivity is a parameter for the total quantity of ions present
in the solution. It can be used for the controlling of:

ductivity (Acid
Conductivity):
Tem per atu re
compensation
Standard
Tem per atu re
When a voltage is set between two electrodes in an electrolyte solution, the result is an electric field which exerts force on the
charged ions: the positively charged cations move towards the negative electrode (cathode) and the negatively charged anions towards the positive electrode (anode). The ions, by way of capture
or release of electrons at the electrodes, are discharged and so a
current I flows through this cycle and the Ohms law V = I×R applies. From the total resistance R of the current loop, only the resistance of the electrolyte solution, respectively its conductivity
of interest.
The cell constant of the sensor is determined by the manufacturer
and is printed on the sensor label. If the cell constant has been programmed in the transmitter, the instrument measures correctly. No
calibration is must be done, the sensor is factory calibrated. Measuring unit is S/cm or S/m.
Conductivity from all ions in the sample, mainly the alkalization
agent. The contribution of impurities is masked by the alkalization
agent.
Only with AMI Powercon acid.
The alkalization agent is removed in the cation column. All cationic
ions are exchanged with H+, all anionic impurities (ions with negative charge) pass through the column unchanged.
The mobility of ions in water increase with higher temperature
which enlarges the conductivity. Therefore, the temperature is measured simultaneous by an integrated Pt1000 temperature sensor
and the conductivity is compensated to 25 °C. Several temperature
compensation curves, designed for different water compositions,
can be chosen.
After cation exchanger (cation conductivity), the temperature compensation curve strong acids has to be set.

Conductivity, PPChem (2012)

The conductivity sensor [A] with integrated temperature sensor is
screwed into the flow cell block [B].
The sample flows via the sample inlet [F] through the flow regulating valve [E], where the flow rate can be adjusted, into the flow cell
block [B], were the specific conductivity of the sample is measured.
The sample leaves the flow cell block via flow meter [C] through the

Option
The sample flows via the sample inlet [G] through the flow regulating valve [C], where the flow rate can be adjusted, into the flow cell
block [B].
The sample is led through the cation exchanger bottle [M] where all
alkalization agent is eliminated. Afterwards the cation conductivity
of the sample is measured with the conductivity sensor [H].
The sample leaves the measuring cell through the flow meter and
the sample collector [J] and flows into the pressure-free sample
outlet.
Temperature is measured with the temperature sensor integrated
the conductivity sensor.
The AMI Deltacon Power with pre-rinse option allows fast replacement of the cation exchanger because the resin is pre-rinsed. Prerinsing has the effect to remove disturbing contaminations contained in the resin, which may cause incorrect measuring values.
The two resin bottles are vented via small tubes connected to the
sample collector [J].
If the pre-rinse option is installed, the sample flows via flow meter
through the per-rinse inlet [D] into the second cation exchanger bottle [F] and from there via pre-rinse outlet [E] through the sample
collector [J] into the waste funnel.
The cation exchanger bottles are vented via two small tubes which
are connected to the flanges [K] and [L].

6.4.Changing the Ion Exchanger
The resin of the ion exchanger changes its color from dark violet to
brown if the capacity is exhausted. The resin should be changed
before no violet resin is left or the cation conductivity rises above
the normal value. At a concentration of 1 ppm alcalizing reagent,
one resin filling will last for roughly 4 months if sample flow is 10 l/h,
or 5 months if sample flow is 5 l/h.

6.8.Quality Assurance of the Instrument
Every SWAN on-line instrument is equipped with integrated, autonom quality assurance functions to survey the plausibility of each
measurement.
For AMI Powercon Specific and AMI Powercon Acid these are:
continuous monitoring of sample flow
continuous monitoring of the temperature inside the transmit-
periodic accuracy test with ultra high precision resistors
Further a manual, menu driven inspection procedure can be carried
out using a certified reference instrument. Running at the same
sampling point as an inspection equipment, the AMI Inspector Conductivity, verifies the measuring results. After enabling the quality
assurance procedure, by defining the quality assurance level, the
instrument reminds the user periodically to run the procedure and
results are stored in a history for review.
Quality
assurance
level
Central feature of the quality assurance function is the assignment
of the monitored process to a Quality assurance level.
There are three predefined levels plus a user level. Hereby the inspection interval, the deviation limits of temperature and measuring
result between the inspection equipment and the monitoring instrument are defined.
Level 1: Trend; Measurement used as an additional informa-

6.8.3Connecting sample lines
See corresponding chapter in the manual of the process monitor
which shall be checked with a reference instrument.
The choice of sampling depends strongly on local conditions on
site. Possible sampling:
via sample point,
via T-fitting or
via piggyback/downstream
– Check certificate; reference instrument certificate not older
then one year.
– Check battery; Battery of the AMI INSPECTOR
Conductivity should be completely charged. Remaining
operating time on display minimum 20 hours.
– Make sure, that both instruments are set to the same
temperature compensation.
– Sensor is in working condition
– the cell constant [ZK] and the temperature correction [DT]
written on the sensor is set in menu 5.1.2.1
– Good order and condition; Flow cell free of particles,
Sensor surface free of deposits.
– Check message list; Review the message list in menu 1.3
and check for frequently alarms (as for example flow
alarms). If alarms occur frequently remove cause before
starting the procedure.
Note:
• avoid ingress of air, use screwed fitting,
• sample as near as possible to the process monitor,
• wait approx. 10 minutes, whilst measurement is running, until
measurement value and temperature are stabilized.
ExampleAs an example following picture shows the connection of the refer-
ence instrument via T-fitting to the process monitor.

output
Signal outputs can be used for driving control units. We distinguish
different kinds of controls:
P-controller: The controller action is proportional to the devia-
tion from the setpoint. The controller is characterized by the
P-Band. In the steady-state, the setpoint will never be
reached. The deviation is called steady-state error.
Parameters: setpoint, P-Band
PI-controller: The combination of a P-controller with an
I-controller will minimize the steady-state error. If the reset
time is set to zero, the I-controller is switched off.
Parameters: setpoint, P-Band, reset time.
PD-controller: The combination of a P-controller with a
D-controller will minimize the response time to a fast change
of the process value. If the derivative time is set to zero, the
D-controller is switched off.
Parameters: setpoint, P-Band, derivative time.
PID-controller: The combination of a P-, an I - and a D-con-
troller allows a proper control of the process.
Parameters: setpoint, P-Band, reset time, derivative time.
