Ethanol (Ethyl Alcohol) is a colorless liquid, which is miscible with water when heat is applied to it. Alcohol has traditionally been manufactured by the fermentation of biomass containing starch and sugars.
Vaisala K-PATENTS® Process Refractometer PR-43-G is used to control and measure the concentration of alcohol in water. The refractometer provides Ethernet and 4-20 mA output signals that can be used as feedback to control the valves in order to achieve always the desired concentration.
