1. SCOPE
This document describes the configuration procedure of SmartScan50 unit for volume measurement
and for flow measurement in custom flumes. The document should be read jointl with the user manual
of SmartScan s stems.
2. OBJECTIVES
Familiarize the user of SmartScan50 with:
•Configuration methods for making volume and flow measurements.
•Configuring volume measurements using manual insertion of strapping tables.
•Configuring volume measurements using semi-automatic insertion of strapping tables.
•Setting 4-20mA configurations for volume and for custom flow measurements.
•Weight calculations using the “K factor”.
3. METHOD FOR MEASURING VO UME
Ultrasonic level sensors measure DISTANCE between the sensor and surface of the target. If distance
between sensor and bottom of tank is known (TOTAL HEIGHT), SmartScan50 can also calculate LEVEL.
For VOLUME, the user should configure SmartScan50 to map between LEVEL and VOLUME.
SmartScan50 provides for a mapping table (also known as strapping table) of up to 24 points. The user
enters a minimum of 8 points and for each point the user defines LEVEL and corresponding VOLUME.
The drawing below illustrates the insertion of LEVEL points into the strapping table:
TOTAL HEIGHT
10 meter
P8 Level = 8 meter Volume = 9600 Liter
P7 Level = 7 meter Volume = 8400 Liter
P6 Level = 6 meter Volume = 7200 Liter
P5 Level = 5 meter Volume = 6000 Liter
P4 Level = 4 meter Volume = 4800 Liter
P3 Level = 3 meter Volume = 3600 Liter
P2 Level = 2 meter Volume = 2400 Liter
P1 Level = 1 meter Volume = 1200

1. Values are entered as LEVEL not DISTANCE.
2. First point indicates bottom of the vessel with minimum volume. As ou add more points to the
strapping table, the level increases corresponding to increasing volume.
3. No need to add a point with a LEVEL zero to represent the bottom of vessel with zero volume.
4. It is forbidden enter an zero value of volume, the first volume value should be greater than zero.
5. It is forbidden to enter a level value which is greater than TOTAL HEIGHT.
6. The thickness of the “slices” does not need to be equal. On the contrar , for different vessel shapes it
is reasonable to define thinner slices where the volume does not increase linearl .
7. Minimum of 8 strapping points is required.

Setting SmartScan50 to VOLUME measurement:
From the main configuration menu set the following parameters:
• T pe of application – Set to Level.
• Units – Set our own units (i.e. meter, inch, feet, etc.).
• Tank height – Set vessel height bottom to sensor.
Do not define the 4-20mA current values et.
From the “additional configuration” menu set the following parameters:
• Pr.0 – Set Ind1 for volume measurement.
• Pr.1 or Pr.2 – Define strapping table.
With SmartScan it is possible to define the strapping table in two methods:
•Manual insertion of strapping table: The user enters both LEVEL and VOLUME values.
•Semi-automatic insertion of strapping table: SmartScan measures LEVEL and the user onl
enters the corresponding VOLUME value.
Loop current values 4-20mA are set after strapping table is configured. SmartScan50 is read for volume
measurement after exiting the configuration menu.
4. MANUA INSERTION OF STRAPPING TAB E
Use “manual insertion of strapping table” when:
•There is a fixed known ratio between LEVEL and VOLUME for our vessel.
•The vessel is of standard shape such as c linder or cone or and it is eas to map LEVEL to VOLUME.
Refer to appendix A for some examples.
•It is not possible to use the semi-automatic mode.
Manual insertion of strapping table is performed with the additional menu configuration - Pr.1.

When entering Pr.1, SmartScan50 will prompt with the first point, P1. For each point the user should
define the required LEVEL and corresponding VOLUME.
For example, for the vessel discussed above:
P1 <Ent>
evel:
Volume, first screen:
Volume, second screen:
001.000 <Ent>
001200 <Ent>
200.000 <Ent>
P2 <Ent>
evel:
Volume, first screen:
Volume, second screen:

P8 <Ent>
evel:
Volume, first screen:
Volume, second screen:
008.000 <Ent>
009600 <Ent>
600.000 <Esc>
Pressing <Esc> after the eighth point, indicates that this point is the last of the table.
5. SEMI-AUTOMATIC INSERTION OF THE STRAPPING TAB E
Use “semi-automatic insertion of strapping table” when:
•The ratio between LEVEL and VOLUME for our vessel is not known.
•The vessel is of unique shape and it is complicated or impossible to map between LEVEL and
VOLUME.

Semi-automatic insertion of strapping table involves a calibration phase using a controlled filling process
and should be performed after interferences were identified and mapped using the “Scan Distance”
technique.
The procedure for semi-automatic insertion of mapping table is as follows:
1. Start with an almost empt vessel or at the first point where the contained volume is known.
2. In semi-automatic mode, the level is measured and calculated automaticall b SmartScan50. Accept
the displa level b pressing <Ent>.
The level measurement ma be incorrect. If so, press <Next> to search for a next level target.
3. Enter the volume value for this level.
4. Fill the tank with known volume value. As a result the level of the material within the vessel will be
increased.
5. For a new point, the unit will calculate the new level.
6. For the new point enter the new volume value.
7. Repeat steps 4 through 6 until the last point is entered.
This method provides more accurate volume calculations when compared with the manual method, but
entails slower calibration due to the need for filling the vessel with known quantit per each point.
This method is activated from Pr.2 of the “Additional menu”.
For example, for the same vessel discussed above, the process is as following:
Important n
ote
:
It is recommended that strapping table points will
not overlap scan distance points
.
Keep a gap of at least 40 cm between the nearest strapping table point and interference. For
example: if there is an interfering echo at 2meter level, use “semi-automatic” level points at 1.6
meter and/or 2.4 meter.

6. OOP-CURRENT CONFIGURATION FOR VO UME
Once the user configures SmartScan50 to volume and sets the strapping table points, it is possible to
configure 4mA and 20mA parameters to represent volume values.
The default value of volume is set automaticall based on the strapping table. The 4mA indication will be
set to the first point (minimum value) and the 20mA indication will be set to the last point (maximum
value).

For example, based on the strapping table of the previous examples, 4mA and 20mA will automaticall
be configured as follows:
• 4mA – 001200
• 20mA – 009600
7. CONFIGURING SPECIA VESSE SHAPES
For vessels which are of odd shapes, VOLUME is not alwa s linear related with LEVEL. The user should
define the “slices” of the strapping tables unevenl and include at least one point for each irregular
mapping.
An example of such “slicing” is illustrated in the next figure.
In this drawing, one can see that a fixed deviation in LEVEL at the vessel bottom, will map to unequal
VOLUME deviations. At higher levels of the vessel the ratio between level and volume is fixed.
In this case, it is better to define more “slices” at the bottom of the vessel. The same guidelines as
defined in previous sections appl to this case as well.
8. WEIGHT CA CU ATIONS
Important n
ote
:
It is recommended to use all 24 strapping t
able points for better accurac .

In some applications the user would like to have the WEIGHT value of the vessel content instead of
VOLUME. Weight can be calculated if both VOLUME and specific gravit densit of the material are
known.
Let the measured volume be “Y” and the material gravit densit be ‘K’, then the weight “X” can be
calculated as follows:
Weight = Specific Gravit Densit * Volume
X = K * Y
The “K Factor” is defined Pr.3 of the “additional menu”. The default value of “K Factor” is 001.000.
9. F OW MEASUREMENT OF CUSTOM F UME
When custom flume measurements are required, the user should configure SmartScan50 to map
between FLOW and corresponding LEVEL.
SmartScan50 provides for a 24 point mapping table (also known as strapping table). For each point the
user should define the level and the corresponding flow for this level. The drawing below illustrates the
LEVEL to FLOW mapping.

increases and so is the flow.
3. The first point can be an value greater than zero.
4. Thickness of strapping table “slices” does not need to be even. For var ing flume shapes it is
reasonable to define thinner slices where the flow does not increase linearl .

Setting SmartScan50 for custom flume measurements:
From the main configuration menu set the following parameters:
• T pe of application – set to Flow.
• Units – choose our own units (i.e. M3/h, GPM).
• Tank height – set to distance from sensor face to bottom of flume
Do not define 4-20mA current values et.
From the “Main menu” set the following parameters:
• PARSH.FLUM
• For custom flume use 0.E01 (for additional information please check SmartScan User Manual)
After defining a strapping table in one of the methods mentioned above, set 4mA and 20mA values as
described in the user manual.
The device is read for custom flume measurement after exit from the configuration menu.
10. OOP-CURRENT CONFIGURATION FOR CUSTOM F UMES
Once the user configures the SmartScan50 to custom flume and sets the strapping table points, it is
possible to configure 4mA and 20mA parameters for FLOW values.
The value of FLOW should be entered manuall according to the strapping table. The 4mA indication
should be configured at the first point (minimum value) and the 20mA indication should be configured
at the last point (maximum value).
For example base on the strapping table in the table above, 4mA and 20mA should be configured as
following:
• 4mA – 000120
• 20mA – 000960

APPENDIX A: VO UME CA CU ATIONS
When the vessel has a c lindrical or conical standard shape, it is eas to calculate the volume of the
vessel with mathematical volume equations. The following figure illustrates c lindrical and conical vessel
volume calculations.
Using the equations, it is eas to calculate the height-to-volume mapping. For example, assume a
c linder shaped vessel with 2-meter radius and 8 meter height. The following table defines the height-
to-volume mapping:
