Product Description A-96.250.611 / 120617 9 Measuring Principle The conductivity of high purity water is determined with a sensor consisting of two metal electrodes. The characteristics of each sen- sor is expressed as cell constant. An alternating voltage (to mini- mize polarization effects) is applied to two electrodes. Depending on the concentration of ions in the sample, a signal results between the electrodes which is proportional to the conductivity of the water. The measuring result is indicated as conductivity. Temperature compensation The mobility of ions in water increase with higher temperature which enlarges the conductivity. Therefore, the temperature is mea- sured 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 com- pensation curve strong acids has to be set. For more information see: Influence of Temperature on Electrical Conductivity, PPChem (2012) Standard Temperature The displayed conductivity value is compensated to 25 °C standard temperature.

AMI INSPECTOR Conductivity Product Description Fluidics The flow cell QV-Flow UP-Con SL consists of the flow cell block [B], the flow sensor [C] and the flow regulating valve [E]. The Swansensor UP-Con1000 SL [A] with integrated temperature sensor is inserted into the flow cell block [B]. The sample enters at the sample inlet [F]. It flows through the flow regulating valve [E], where the flow rate can be adjusted. Then the sample flows through the flow cell block were the conductivity and temperature of the sample is measured. The sample leaves the flow cell block via flow meter through the sample outlet [D].

Maintenance A-96.250.611 / 120617 29 6.4. Quality Assurance of the Instrument Every SWAN on-line instrument is equipped with integrated, auton- omous 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- ter case  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 Con- ductivity, 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 in- spection interval, the deviation limits of temperature and measuring result between the inspection equipment and the monitoring instru- ment are defined.  Level 1: Trend; Measurement used as an additional informa- tion to follow the process indicating trends.  Level 2: Standard; Monitoring of conductivity. In case of in- strument failure, other parameters can be used for process monitoring.  Level 3: Crucial; Monitoring of critical processes, value is used for control of another part or subsystem (valve, dosing unit, etc.). Additional level:  Quality level 4: User; User defined inspection interval, maxi- mal deviation of temperature and measuring result.

Maintenance A-96.250.611 / 120617 31 6.4.2 Pre-test  Reference instrument: AMI INSPECTOR Conductivity – Check certificate; reference instrument certificate not older than one year. – Check battery; Battery of the AMI INSPECTOR Conductivity should be completely charged. Remaining operating time on display minimum 20 hours. – Disable temperature compensation (set to “none”)  On-line instrument: Monitor AMI Powercon: – 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 occurring alarms (as for example flow alarms). If alarms occur frequently remove cause before starting the procedure. 6.4.3 Connecting 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 NOTICE: • 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. Example As an example following picture shows the connection of the refer- ence instrument via T-fitting to the process monitor.

Program List and Explanations A-96.250.611 / 120617 53 As control 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. Ziegler-Nichols method for the optimization of a PID controller: Parameters: Setpoint, P-Band, Reset time, Derivative time The point of intersection of the tangent with the respective axis will result in the parameters a and L. Consult the manual of the control unit for connecting and program- ming details. Choose control upwards or downwards.
