2. Product Description

This chapter contains technical data, requirements and performance data.

2.1. Description of the System

The portable AMI INSPECTOR instrument is a complete monitoring system mounted on a small panel with supporting stand and a rechargeable battery for stand-alone operation (>24h), designed as an inspection equipment for quality assurance of online process monitors.

pH Measuring

Principle

(simplified)

The pH measurement is based on a voltage measurement. A voltage can only be measured between two different potentials, therefore, the pH measuring chain contains a measuring electrode and a reference electrode. The reference electrode maintains a constant potential whereas the potential of the measuring electrode changes with the pH value. The voltage which results from this potential difference is measured and displayed on the transmitter as pH value. The measuring chain is designed so that the voltage is zero at pH 7.

pH Electrode The Swansensor pH SI is a combined electrode with liquid electro-

lyte (KCl) for the measurement of pH.

Features General Features of AMI INSPECTORs are:

 Battery life after full charge:

– >24h at full load (use of 3 relays, USB, signal output, logger) – >36h at minimum load (use of logger only)

 Charging time: approx. 6 hours  Controlled shut-down if battery is empty.  Display of remaining battery life in hours.  For longer battery life the back light of the LC Display is dis-

abled.

 Continuous operation using power adapter. The battery

should be discharged at least once a month (normal usage until the monitor automatically shuts down).

Battery The Li-Ion battery is located in the housing of the AMI transmitter.

See chapter Power Supply, S. 19 regarding power supply and charging of the battery.

Fluidics The flow cell (QV-Flow) consists of the flow cell block [E] and the

vessel [G]. The pH sensor [A] and the temperature sensor [B] are screwed into

the flow cell block [E]. The sample enters at the sample inlet [C]. It flows through the flow

regulating valve [D], where the flow rate can be adjusted. Then the sample flows via the flow sensor [F] and the flow cell block [E] into the vessel [G], were the pH of the sample is measured. The pH value depends on the sample temperature. The measuring value of the temperature sensor [B] is used to recalculate the pH measuring value to a predefined average sample temperature.

The sample leaves the vessel via flow cell block through the sample outlet [H] and flows into the drain [I].

6.4. Calibration

Process

pH Calibration

The process calibration is based on a comparative measurement of the on-line instrument with a calibrated comparative electrode. Perform a valid manual measurement with the calibrated comparative electrode. Then compare the measuring value with the on-line instrument and if necessary, enter the correct measuring value in the menu <Maintenance/ Electrode 1/2 /Process Cal.> of the on-line instrument. The deviation of the measuring values is shown as offset in mV. Select <Save> and press <Enter> to save the correct measuring value.

Standard

pH Calibration

The ideal pH electrode has an offset of 0 mV at pH 7 and a slope of

59.16 mV/pH unit. Real electrodes differ from this ideal. Therefore, pH electrodes are calibrated with two buffer solutions, of different pH values.

6.5. Quality Assurance of the Instrument

Every SWAN on-line instrument is equipped with integrated, autonomous quality assurance functions to survey the plausibility of each measurement.

For AMI pH-Redox these are:

 continuous monitoring of sample flow  continuous monitoring of the temperature inside the transmit-

ter case

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 pH 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 assur-

ance 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-

tion to follow the process indicating trends.

 Level 2: Standard; Monitoring of several parameters of a pro-

cess (e.g. oxygen, hydrazine and pH in feedwater). In case of instrument 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.

6.5.2 Pre-test

 Reference instrument: AMI INSPECTOR pH:

– Check certificate; reference instrument certificate not older

then one year.

– Check battery; Battery of the AMI INSPECTOR pH should

be completely charged. Remaining operating time on display minimum 20 hours.

– Disable temperature compensation (set to “none”)

 On-line instrument: Monitor AMI pH/Redox:

– 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.

6.5.3 Connect instruments

The AMI Inspector pH sample inlet is equipped with a serto fitting for stainless steel pipes. To connect the sample stream to the AMI Inspector pH proceed according to chapter Serto Fitting Stainless

Steel, S. 32. The choice of sampling depends strongly on local con-

ditions on site. Possible sampling:

 via Sample point,  via T-fitting or  as piggyback / downstream

NOTICE: Important for correct measurements are in any case:

• 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:

Sampling via

T-fitting

The reference instrument, AMI Inspector pH, is connected parallel to the Monitor AMI pH-Redox by installing a T-Fitting at the sample inlet tube and dividing the sample stream to each instrument.

5 Installation

5.1 Sensors

5.1.1 Flow

5.1.1.1 Flow measurement: Select the type of flow sensor if a flow sensor

is installed. Possible flow sensors: None; Q-Flow; deltaT

5.1.2 Parameters:

5.1.2.1 Type of Sensor: Set the type of installed sensor.

Possible types: pH or Redox

5.1.2.2 Sensor Check: Not yet implemented. Set to off.

5.1.3 Temperature:

5.1.3.1 Temp. Sensor: The pH measurement is temperature dependent

therefore it is possible to install a temperature sensor. Possible settings: Temp. Sensor; <yes>, <no>

If <no> is set the measuring value is compensated with the default temperature.

5.1.3.21 Default Temp.: If no temperature sensor is installed, set the default

temperature to the assumed average temperature of the sample. The measuring value is then compensated with this value.

5.1.3.3 Temp. Compensation (only available for pH measurement)

5.1.3.3.1 Comp.: Choose the compensation model which fits best to your application.

Available compensation models: Nernst, non-linear, coefficient. We recommend: Nernst compensation for potable water, waste wa-

ter, swimming pools, non-linear or coefficient for high purity water.

5.1.40 Standards: A temperature curve is programmed for SWAN standard 1, pH 7 and SWAN standard 2, pH 9. If you want to use your own standards you can readjust the temperature curve according to your standards.

5.1.5.1 Standard 1: Assign the measured pH value to the according tem-

perature from 0–50 °C in steps of 5 °C.

5.1.5.2 Standard 2: Assign the measured pH value to the according tem-

perature from 0–50 °C in steps of 5 °C.

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 programming details. Choose control upwards or downwards.

5.3.4 Input: The functions of the relays and signal outputs can be defined depending on the position of the input contact, i.e. no function, closed or open.

5.3.4.1 Active: Define when the input should be active:

5.3.4.2 Signal Outputs: Select the operation mode of the signal outputs

when the relay is active:

5.3.4.3 Output/Control: (relay or signal output):

5.3.4.4 Fault:

5.3.4.5 Delay: Time which the instrument waits, after the input is

deactivated, before returning to normal operation. Range: 0–6‘000 Sec

5.3.2.1

Function = Fieldbus:

No: Input is never active.

When closed Input is active if the input relay is closed

When open: Input is active if the input relay is open

Cont.: Signal outputs continue to issue the measured

value.

Hold: Signal outputs issue the last valid measured value.

Measurement is interrupted. Errors, except fatal errors, are not issued.

Off: Set to 0 or 4 mA respectively. Errors, except fatal

errors, are not issued.

Cont.: Controller continues normally.

Hold: Controller continues on the last valid value.

Off: Controller is switched off.

No: No message is issued in pending error list and the

alarm relay does not close when input is active.

Yes: Message E024 is issued and stored in the mes-

sage list. The Alarm relay closes when input is active.
