2.3 Sensor installation
Preparation.
It is important that the sensor is installed in a straight pipe run, preferably with minimally 5
diameters of straight pipe run upstream, and 3 pipe diameters of straight pipe run
downstream.
In addition, the probe must be installed in a vertical pipe, or sidewise in a horizontal pipe.
This implies that the probe must not be installed on top of the pipe, nor on the bottom, as
eventual gas bubbles may accumulate on the sensor surface(s). Installation on a vertical
pipe section is preferred, as gas bubbles are always able to escape.
Summary:
•Install the probe or spool section with 5xD length of straight pipe length upstream and 3xD
of straight pipe length downstream.
•Avoid installation near dosing valves.
•Vertical pipe installation is preferred.
•Horizontal pipe installation: Sensors must be installed sidewise.
2.4 Installing the cables
Refer to the figures below for general mounting overview of the cables.

3. Configuration.
Configuration can be done through the
configuration menu, by pressing the exit icon on
the main measurement screen:
Figure 9: MAIN MENU page
NOTE: The shown icons depend on your access
level.
3.1 Introduction
Once you have chosen the configuration mode, you will be able to establish specific
operating parameters of the analyzer. These parameters include:
1. Sensors, including parameters of the probe
2. 4~20 mA output, including scaling, source choice and error handling
3. 4~20 mA input, for external compensation, i.e. CO2 compensation.
4. Display, i.e. choice of results to be displayed
5. Alarm output setting, i.e. type, trip points, and choice of source
3.1.1 Touch Screen Functions
NOTE: The backlight will automatically turn off after 30 minutes. To turn it on back again,
simply touch the screen at any location.
The touch screen display has the following functions:
•to display measurement results in values or graphics
•to change parameters and/or sources, like for instance the selected liquid
The LED located at the bottom side of the display area lights if the display is powered up.
At the right side of the display six buttons are located with the following functions:
•[SYSTEM] : NA
•[F1] : changes the access level to access level 1 and changes the page to
the first measurement page
•[F2] : turns the backlight OFF (touching the screen will turn the backlight on)
•[F3], [F4] : NA
•[F5] : saves the current page of the display to the USB stick
3.1.2 Preparations
Before attempting to configure the transmitter, define the following:
The desired output settings for the 2 4~20mA outputs, i.e.
•What measured value you wish to transmit through the 2 pcs 4~20 mA outputs.
•The scaling of these parameters.
•What to do when the system detects problems, i.e. gas bubbles.
Consider which parameters you wish to be viewed during normal operation.
•I.e. Concentration for 1st parameter shown
•I.e. Temperature for 2nd parameter shown
Consider which parameters need to be monitored by the alarms.

Software Version: 2.2.7 Date: 8 December, 2009 Page 13/46
•What measured value (i.e. concentration) you wish to check.
•Whether you wish to use 2 alarms for hi-hi lo-lo configuration.
•If the analyzer is used for several different products: alarm trip points for each
product.
3.2 Analog Output configuration
This section describes how you can configure your 4~20mA outputs:
With these settings, you can set the following:
•To choose the result to transmit through the 4~20 mA outputs.
•The scaling of these parameters.
•What the system should do when the system detects problems, i.e. gas bubbles.
Access level 2 is required (supervisor).
The access code is 7410.
3.2.1 Procedure
Through the main menu, chose configure, then
outputs.
Both outputs can be configured, as per below.
Figure 10: 4-20 mA OUT 1 page
3.2.2 Output source
►From the Configuration menu, press [4-20 mA
OUT ]
►Choose [Configuration] and [4-20 mA OUT 1
or 2]
►On the 4-20 mA OUT # menu, press [Source OUT # name] to go the Assignment page 1
menu
►Here you can choose between the Calculated polynomial (the concentration) and one of
the measured value’s
If you choose for Calculated Polynom:
►Press [Polynom 1 or 2 calculated]
You will be returned to the 4-20 mA OUT # menu.
If you chose for one of the Measured values:
►Press the button [More settings]
►Press the button of the desired value
You will be returned to the 4-20 mA OUT # menu.
Figure 11: ASSIGNMENT PAGE 1 page
3.2.3 Output Scaling
The analog output is of the 4~20 mA type.
When you wish to scale your output to a range of 10 to 15 wt%, the procedure is as follows:
►Press [4 mA Equals]
►Enter the value 10 (wt%), the lowest value, corresponding to 4 mA
►Press [Enter] (automatic return to the 4~20 mA OUT1 or 2 page)
►Press [20 mA Equals]
►Enter the value 15 (wt%), the highest value, corresponding to 20 mA
►Press [Enter] (automatic return to the 4~20 mA OUT 1 or 2 page)

Software Version: 2.2.7 Date: 8 December, 2009 Page 14/46
CAUTION:
Scaling the output to a high range, i.e. 0~100 wt%, results in loss of accuracy. The accuracy
of the output is 0,05 % of scale. Choosing a smaller range (difference between low and high
value) results in a better resolution. In the above example, the accuracy of the output is 0,1%
of (15-10), which equals 0,0025 wt%.
3.2.4 Error communication through analog outputs
During an inline analysis, conditions may not always be perfect to perform a correct
measurement. The analyzer automatically detects when the liquid is not homogeneous, or
when gas bubbles are present, generates errors and initially holds its last valid reading.
In most processes, upset conditions may occur incidentally, due to not completely dissolved
gases. The analyzer freezes the measurement during these conditions.
Too long freezing may lead to a constant output, which in turn may lead to the conclusion
that the process is perfect. To signal a too long duration of upset process conditions, the
analyzer can react to these errors in four different modes.
•Force Low: force output to 3mA after XXX seconds
•Force High: force output to 20mA after XXX seconds
•Force Update: force output to maintain measurement (only for Temp and Gain)
•Hold last: Hold last correct measured value
Determine first:
•How long do I allow the system not to signal any upset process conditions?
•What milli-Amp value do I wish to receive when erratic conditions continue for a too
long period of time?
From the analog output menu, press Error Mode
Figure 12: ERROR MODE OUT 1 page
Example: The output should force low when 120
seconds of continuous loss of signal occurs.
►Press [Error Mode] on the 4~20 mA output 1 or
2 menu.
►On the Error mode OUT 1 page, press the
button of your choice:
►Press the [Force Low]
►Enter “120” (via pop up keypad)
►Press [Enter]
►Press [Accept]
After the specified number of seconds, the 4~20 mA OUT will be forced to the specified level
(Low level is 3 mA, High level is 21 mA).
Repeat this procedure for 4~20 mA OUT 2
NOTE
When you wish to output temperature, set to “Force update” (no time can be set).
3.2.5 Decay time
Smoothing is strongly recommended, since it gives you more accuracy. In addition, rapid
changes in concentration are being smoothed, hence the output value more represents the

Software Version: 2.2.7 Date: 8 December, 2009 Page 15/46
“bulk” value of the liquid. When fast response is not required, we strongly recommend setting
the τ63 time between 5 and 20 seconds. Since smoothing affects the response time, the best
setting is a trade-off between accuracy and response time.
A decay rate of 5 seconds is recommended for most applications.
Figure 13: DECAY TIME page
3.3 Display configuration
Purpose:
•Define the parameters you wish to be viewed
during normal operation.
•Define damping.
•Define the resolution on the display.
3.3.1 Selecting the results
Normally, you wish to view the concentration as main parameter, and the temperature as
second parameter (shown small). Should your analyzer be capable of measuring more
chemical components, you may wish to select another component. In addition, it is possible
to view other, secondary parameters, such as sound speed or Ultrasonic attenuation, for
specific evaluations.
The procedure is as follows:
Example: Concentration, i.e. Original Extract in ºP must be the primary measurement result.
The temperature should be shown in smaller numbers, as secondary result.
NOTE: This procedure does not affect the output and alarm configurations.
►From the Configuration menu, press [Display]
►On the Display configuration menu, press [Source 1 name] to go the the Source 1 menu
►Here you can choose between the Calculated polynomial (the concentration) and one of
the measured value’s
If you choose for Calculated Polynom:
►Press [Polynom 1 or 2 calculated]
You will be returned to the Display configure menu.
If you chose for one of the Measured values:
►Press the button [More settings]
►Press the button of the desired value
You will be returned to the Display configure menu.
Figure 14: DISPLAY CONFIGURE page
NOTE: The same steps have to be followed to set Source 2
3.3.2 Setting the display resolution
This menu allows you to toggle between 2 digits and 3 digits resolution. This setting does not
affect the output resolution. The 3-digit resolution may be selected when additional readout
accuracy is required, which is useful during field calibrations. For additional readout
accuracy, it is recommended to apply some display smoothing too. See next section for
details.
►On the Display configuration menu, press [Resolution]

Software Version: 2.2.7 Date: 8 December, 2009 Page 16/46
►Press [2Digits] or [3 Digits] on the Resolution page (automatic return to the Display
configuration page)
3.3.3 Display smoothing
This setting is the same as the decay time for the analog outputs. The result is that
concentration values are smoothened before they are sent to the output.
A decay rate of 5 seconds is recommended for most applications.
3.3.4 Graph scaling
Purpose:
During normal operation of the analyzer, you can activate additional screens, such as the
graphs, allowing you to see the trend of the results as configured in the previous section. The
graphs show the trend of the results over the last 15 minutes of operation.
The scaling of the graph is done in this section.
•Define the scales of the 2 graphs (Y-axis starting and ending points).
•The plotted results are those which were configured in the display menu.
Once you have reached the menu through Configuration – Display:
►Press [Trend configuration]
►Press [Min/Max value y-axis 1/2]
Now you can enter the values that should
correspond to minimum and maximum of the y-axis
1 and y-axis 2 (via pop-up keypad)
►Press [Trendline sampling time]
Now you can enter the time that should correspond
to the time a trend value is written on the graph.
NOTE: The graph will plot the results which are
monitored by the display. Should you wish to plot
other results, then this is only possible by changing
the display source value.
Figure 15: DISPLAY CONFIGURATION GRAPH 1 page
3.3.5 Backlight turn off time
This setting allows you to set the time that the backlight has to be turned OFF automatically.
If the backlight doesn’t have to be turned OFF, enter 0 minutes. Touching the screen will turn
the backlight ON. The set time has a fixed cycle
and starts when the display is powered ON, so it
can happen that if you touched the screen the
backlight is turned OFF within the set time.

When replacing a probe, it is necessary to enter
the probe constants as supplied on the Probe
Calibration Data Sheet (PCDS).
Figure 16: SENSOR page
3.4.2 Procedure
•Obtain the Probe Calibration Data Sheet. The serial number of the probe is indicated
on the sheet.

Software Version: 2.2.7 Date: 8 December, 2009 Page 17/46
•From the main menu, choose Configuration – Sensor – US sensor
•Check or modify the data as indicated on the data sheet
NOTE: If a probe is replaced, the previous data sheet is no longer valid.
3.4.3 Instructions:
►On the Configuration menu, press [Sensor]
►On the Sensor menu Press [Ultrasonic]
The following menu appears:
►Enter the appropriate values and confirm with
[Enter] to return to this page.
►Press [Auto Dead time Cal.] to choose ON or

3.4.4 Auto dead time
3.4.4.1 Introduction
The auto dead time function takes care of variations in the “dead time”, a probe-specific
variable which is determined in the factory and is used to measure precisely the actual transit
time in the liquid. The dead time is an important value and may change in time.
The instrument has a built-in feature that performs this vital calibration automatically during
normal process conditions, carefully checking that the necessary circumstances are meeting
the same conditions as in the factory, during the final calibration and quality control
procedure.
When leaving the “Ultrasonic Probe Configuration” page the setting of the auto dead time is
automatically set to “OFF”.
3.4.4.2 Advantages.
The Auto-dead-time enhances the reliability of the measurement, as it continuously checks
and adapts the dead time value without operator attention and the need to return the probe
to the factory for recalibration. When the Ultrasonic connecting cable is replaced with the
same, a longer or a shorter cable, there is no need to manually adjust the dead time.
3.4.4.3 Procedure.
►With the sensor in water, free of gas bubbles, with a low concentration solids and
dissolved components.
►Press Auto Dead Time and select ON.
When the probe is installed in a filled pipe line, and process conditions are considered to be
stable, which is determined by the analyzer, it will perform continuous measurement of the
system dead time. You are still able to enter a number in the Dead Time field, however the
instrument will automatically correct the entered value to the correct value. The Auto Dead
Time is only working if the “Ultrasonic Probe Configuration” page is displayed.
►When the number in the field is giving a stable value (normally between 1100 and 1200),
Press Auto Dead Time and select OFF or leave the page.
3.5 Alarm configuration.
3.5.1 Introduction
Alarm relays are provided for monitoring specific measured concentrations. The analyzer
allows you to define which parameters are monitored, and at what values the relays should

Software Version: 2.2.7 Date: 8 December, 2009 Page 18/46
be possible. In addition, you may select whether the alarms are activated during fault
conditions (Normal) or activated when no alarm is present (inverted operation).
3.5.2 Preparation.
•Determine which value you wish to monitor with each alarm.
•Determine whether you wish the alarm relay contacts to be activated during normal
operation (no alarm) or during a fault condition. This decision has consequence for
the alarm wiring, as a Normally Open (NO) contact will be closed when the value falls
within the low and high limit.
•Determine high and low trip points for each alarm.
NOTE
The analyzer has a database with specific set points for each individual beer type. As the
adjustment of the set points is liquid type dependant, the procedure for changing the set
points is covered in chapter “Liquid selection and editing”, paragraph “Editing liquids”.
3.5.3 Procedure
►Through the Configuration menu, press [Alarm]
►After choosing Alarm 1 or Alarm2, press [Alarm 1/2 name/unit] to choose the parameter
to be monitored.
►Here you can choose between the Calculated polynomial (the concentration) and one of
the measured value’s
If you choose for Calculated Polynom:
►Press [Polynom 1/2 calculated]
You will be returned to the Alarm 1 or 2 menu.
If you chose for one of the Measured values:
►Press the button [More settings]
►Press the button of the desired value
You will be returned to the Alarm 1 or 2 menu.
Figure 18: ALARM 1 page
NOTE: Usually this would be the main parameter, i.e. concentration in %w/w.
►Press [Low Alarm]
►Enter the value that should correspond to low alarm (via pop up keypad)
►Press [Enter] (automatic return to the Alarm 1 page)
►Press [High Alarm]
►Enter the value that should correspond to high alarm (via pop up keypad)
►Press [Enter] (automatic return to the Alarm 1 page)
►Press [Accept] (after pressing Accept it may take up to 10 seconds to return to the Alarm
configuration page)
Repeat these steps for Alarm 2 if desired.
IMPORTANT:
Changes made to the alarm settings of an individual liquid will remain valid until the alarm
settings for this liquid are changed again.
3.6 Trouble shooting
3.6.1 Preparation.
•For trouble shooting, it is important to record as much data as possible

Software Version: 2.2.7 Date: 8 December, 2009 Page 19/46
•Use of the memory stick feature allows you to log measurement data
•The memory stick can be used to download all settings of the analyzer
•The memory stick can be used to download a typical waveform, which can be useful
for trouble shooting
•Record other observations, i.e. pipe full/empty and/or laboratory gathered samples
with results and time tag, in order to compare with the analyzer results
•For factory back-up, you can send stored files with your comments, facilitating fast
response from the factory
3.6.2 Memory Stick Logging
XSlide the empty USB memory stick in the U-A connector of the display
XCheck that the USB memory stick flashes, indicating write/read actions
XWait until the continuous flashing stops (the display is making folders on the USB
stick, this should take about 5 minutes)
XOpen “Logging” in the Information /
Diagnostics menu
XEnter the log sampling time
XPress “Start logging”. The main
measurement page should indicate that the
logging process is active.
All main data, detail data, and a time tag is
recorded in a temporary file on the memory
stick.
Figure 19: LOGGING page
IMPORTANT
Never take out the memory stick without stopping the log process first
ALWAYS wait until the memory stick stops flashing (may take several minutes)
The data will be stored in the following folder: RHO\SAMPLE\. In this folder, you will find
folders, indicating the day in the format YYMMDD. After day, the last data is assembled in a
.CSV file, and a new folder is created for the next day of logging.
The .CSV files can be easily opened with Excel. The stored .BIN files are temporary files and
cannot be opened, converted or used otherwise.
3.6.3 Procedure to stop logging on USB memory stick
XPress “Stop & Save Log to USB”
XWait until the page “Saving data to USB” is disappeared from the screen, this may
take up to 5 minutes
XRemove USB stick and check the log data with Excel
