1. General information
1.1. Applications
The main application of SMART EBULLIOMETER is for volume content measurement of ethyl alcohol in
wine but it is possible to be used for volume content measurement of ethyl alcohol in other low alcohol
content liquids - for example beer.
1.2. Working principle
The ebulliometer working principle is based on calculation of volume content of ethyl alcohol as a function
of difference between distilled water boiling temperature and sample boiling temperature at the one and same
atmospheric pressure.
A = f(dT), [%]
where:
A- volume content of ethyl alcohol [ % ]
dT = Tw - Ts
Tw - distilled water boiling temperature.
The distilled water boiling temperature depends on atmospheric pressure.
Ts - sample boiling temperature.
The sample boiling temperature depends on the atmospheric pressure at the time of measurement, on
the alcohol content and also on the content of the other components included in the sample.
1.3. Working using classic ebulliometer
When working with a classic ebulliometer the laboratory assistant must :
1) To measure distilled water boiling temperature Tw
2) To measure sample boiling temperature Ts
3) To calculate temperature difference dT
4) To determine volume content of ethyl alcohol Afrom the ebulliometric table depending on dT.
1.4. Working using SMART EBULLIOMETER
When working with SMART EBULLIOMETER the laboratory assistant must :
1) To start sample measurement.
All other activities are fully automated as:
- Distilled water boiling temperature Tw is calculated, based on measured atmospheric pressure from the
embedded precise atmospheric pressure sensor.
- Sample boiling temperature Ts is measured from the precise temperature sensor immersed in the boiling
sample and the built-in boiling temperature determination algorithm.
- Temperature difference dT is automatically calculated.
- Volume content of ethyl alcohol A is automatically calculated based on calculated dT and the built-in
ebulliometric table

4. Installing and preparation for work
Place the meter in vertical position on a smooth and level surface (table, writing desk, etc.).
Connect the cooling water to water supply network or another source of cooling water as shown in
Fig. 3.
The source of cooling water shall meet the following requirements:
- Temperature - not higher than 25°C
- Flow rate - from 0.5 to 1.0 L/min.
Put both Vinyl hoses 8mm x 1.5 m and tighten the fixing clamps at the inlet and outlet of the
cooling system.
Connect the cooling system inlet to a water supply network or another source of cooling water as
shown in Fig. 3. Consult a technician for supplying of suitable part.

Water at the device cooling system outlet is taken away to the sewerage network by gravity.
Turn on cooling water, adjust the flow rate from 0.5 to 1.0 L/min (using tap) and check for leaks at
connection points.
Attention: Make sure the output hose of cooling system is not blocked (folded, pressed, squeezed etc.).
The output hose blockage leads to flooding of measuring system and serious damage of the device
Remove the polyethylene bag covering the inlet of the measuring system.
Put the free end of the 3 mm x 1.5 m vinyl hose connected to the discharge valve (Fig. 2) into a suitable
vessel for collection of samples measured or directly to the sewerage.
Connect the power cable to the meter.
Connect the power cable to a mains supply source of nominal voltage in accordance with the nameplate at
the rear panel of the device.
Attention: Power device from 3-prong grounded schuko plug only
5. Working with the device
5.1. Starting up
After the connecting the power cable to the electrical network and turning the power on using <On/OFF>
switch ( see Fig. 5) the device start its work with a procedure that checks all critical components ( power
block, sensors etc.) and also deleting of obsolete files from the build-in SD card - data collection files, error
log files and diagnostic files ( see items 5.4.7.1, 5.4.7.2 and 5.4.7.3 ).
During the components checking procedure is in progress, the current software version is displayed
at the bottom of the display (for example "Firmware version: ET01.01B")
In case of a fault is detected in some of the components, the corresponding error message appears
on the display.
After a checking procedure completes, the device beeps.
Note: Please see chapter 5.4.5.6 about enabling and disabling the buzzer.
5.2. Home screen
The Home screen appears after the Starting Up procedure complete.

From this screen you may select the icon "Measurement" or "Settings" using the buttons <Left
arrow> / <Right arrow>.
5.3. "Measurement" mode
"Measurement" mode is designed to determine the boiling point of the sample(wine) and calculating the
volume percentage of ethyl alcohol.
Attention: During this procedure tap water must flow through the cooling system ( see point 4).
Before starting "Measurement" mode the measuring system should be flush with wine to be measured.
Close the discharge valve (see Fig. 2), and fill the measuring system to the top with wine to be measured
(about 100 ml). Then open the discharge valve to evacuate the measuring system. This way the measuring
system will be flushed and prepared for measurement.
Close the discharge valve, measure another 50 mL from the sample and pour it into the inlet of the
measuring system.
Adjust the wine volume to the printed mark ( see Fig. 6 ) on the reactor by opening the valve to drain the
excess wine. During the volume adjustment, the mark should be at your eye level.
Fig. 6

Attention: The precise wine volume is very important for the accuracy of ebulliometer!
After the starting of "Measurement" mode ( see item 5.3.) the user should select the wine type that
will be measured - Dry, semi-dry, semi-sweet, sweet, User type 1, User type 2, ... User type 10.
Note: The following parameters can be entered for each of the above types of wines:
- Sugar content
- Alcohol correction
- Note
For more details about how to edit the parameters of the wine types, see item 5.4.2. - Wine type settings
To select the wine type you will measure, use buttons <Arrow up> / <Arrow down> and then confirm with
button <OK>.
Below is shown an example of the panel with started measurement process:
Wine type - the selected wine type
Note - note for the selected wine type
Sugar content - sugar content for the selected wine type
Alcohol correction - alcohol correction for the selected wine type
Current temperature - currently measured temperature value of the sample (wine)
Atmospheric pressure - currently measured atmospheric pressure value
Time - the elapsed time since the start of the measurement process

The measurement process is fully automated and no need any actions from the user.
If the user wants to break the measurement process this can be done using the buttons <MODE> or
<HOME>.
5.3.1. Automatic reading of the boiling point and the percentage of alcohol
In the device is embedded a boiling temperature determination algorithm based on multiple criteria.
After all criteria are met the measurement process is stopped, volume content of ethyl alcohol is
calculated and the results are shown as shown below:
Wine type - the selected wine type
Note - note for the selected wine type
Sugar content - sugar content for the selected wine type
Alcohol correction - alcohol correction for the selected wine type
Alcohol content - Calculated sample (wine) alcohol content
Atmospheric pressure - measured atmospheric pressure
Sample boiling temperature - measured sample (wine) boiling temperature
Note:
Depending on the type and amount of additional substances (except ethyl alcohol and water) in the
measured wine, the boiling process may be uneven, which leads to cyclical fluctuations in the measured
temperature and the inability to automatically read the boiling temperature. In such cases, the user can
manually read the boiling temperature of the wine (see item 5.3.2.).
5.3.2. Manual reading of the boiling point and the percentage of alcohol
Once the measurement process reaches a relatively stable sample temperature, an icon appears in
the upper right corner of the screen indicating that the user can perform a manual reading by
pressing the <OK> button.

This way, the temperature displayed on the screen at the time of pressing the button <OK> is taken as the
boiling temperature of the sample and is used to calculate the percentage of alcohol in the sample.
In this case, the results are displayed as follows :
Manually read value - An icon indicating that the calculated result for alcohol content is made on the basis of
a manually read sample (wine) boiling temperature.
Wine type - the selected wine type
Note - note for the selected wine type
Sugar content - sugar content for the selected wine type
Alcohol correction - alcohol correction for the selected wine type
Alcohol content - The calculated sample (wine) alcohol content
Atmospheric pressure - measured atmospheric pressure
Sample boiling temperature - measured sample (wine) boiling temperature
After the measurement completion open the discharge valve to evacuate the measuring system.

In case you have a printer connected to the device and it is selected ( see item 5.4.6.5. ) the measurement
results will be printed out automatically.
Example of printout in case of automatic reading of the boiling temperature:
Example of printout in case of manual reading of the boiling temperature:
If you want to print the results again, press the <PRINT> button located on the front panel of the device or
use the F6 key from the USB keyboard.
Notes:
1. Please ignore the measurement result of the first measurement done after measuring the water boiling
temperature determination. Repeat the measurement with a new sample from the same wine.
2. Please be aware the residual sugar in the wine affects the measurement result accuracy. For achieving
best results it is recommended the meter to be calibrated with wines with known alcohol content and sugar

content. That differs from the sugar content of the tested samples with no more than ±5%. The calibration
value can be entered as a acohol correction for the corresponding wine type. To enter this value use
"Alcohol content correction"( see item 5.4.2.2. ).
3. In case the atmospheric pressure sensor is disabled (see item 5.4.6.4.) and you have not performed
water measurement in "Water" mode in the previous 24 hours, a warning message will appear on the
