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 A from 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
